The opening 62 bends the two opposing side wall parts 63 and 64 to the shelf 60 side, and provides the side walls 63 and 64 with elongated holes 63a and 64a. The elongated holes 63a and 64a are provided with heights of the rising pieces 34 and 38, respectively. Plate-like projecting pieces 65 and 66 having rising portions 65a and 66a having the same height are locked by screws 65b and 66b. As shown in FIGS. 7C and 7D, the projecting pieces 65 and 66 are bent plate-like bodies having holes 65c and 66c to form rising portions 65a and 66a that project obliquely. Accordingly, as shown in FIG. 7A, the projecting pieces 65 and 66 are fixed on the shelf 60 side of the surface plate 61 by screws 65b and 66b. Further, at the edge of the opening 62, the first positioning portions 30A, 40A, 50A and the second positioning portions 30B, 40b with respect to the DC power supply panel 30, the AC power supply panel 40, and the FFTU power supply panel 50 are provided.

In addition, screw holes 67 and 68 for attaching the screws 30e and 30f are provided at the edge of the opening 62.

Next, the operation of the power supply device according to this embodiment configured as described above will be described.
First, a case where two DC power panels 30 and 30 are mounted on the shelf 60 will be described.
As shown in FIGS. 7A and 7B, the portions of the holes 65 c and 66 c of the projecting pieces 65 and 66 are located at the side walls 63 and 64 at the DC display position provided on the surface plate 61 of the shelf 60. And are fixed to the elongated holes 63a and 64a through the holes 65c and 66c with screws 65b and 66b. As a result, when the two DC power supply panels 30 and 30 are mounted on the shelf 60, the projecting pieces 65 and 66 have the notch portion 35 of the first positioning portion 30A and the notch portion 36 of the second positioning portion 30B. Protrusions that fit together.

  Next, one DC power supply panel 30 is inserted into one side (the left side in the drawing) of the opening 62 of the shelf 60. At this time, one DC system power panel 30 is allowed to be inserted so that the rising portion 65a of the protruding piece 65 fits into the cutout portion 36 on one side. Then, like the conventional DC system power supply panel (similar to the left side connection in FIG. 11), the connector 32 is engaged with the connector 64 of the shelf 60 and both are connected.

Next, the remaining DC power panel 30 is inserted into the other side (the right side in the drawing) of the opening 62 of the shelf 60. At this time, the remaining DC system power supply panel 30 is allowed to be inserted so that the rising portion 66a of the protruding piece 66 fits into the cutout portion 35 on one side. Then, like the conventional DC system power supply panel, the connector 32 meshes with the connector 64 of the shelf 60, and both are coupled.
As described above, the two DC power supply panels 30 and 30 are attached to the normal positions of the shelf 60 as shown in FIGS. 1, 2, 7, and 8.

Next, for example, a case where the DC power supply panel 30 on the right side of FIG.
Since the three types of shelves 60 are common, all of the DC power supply panel 30, the AC power supply panel 40, and the FFTU power supply panel 50 are attached to the power supply device.
However, if the AC power supply panel 40 or the FFTU power supply panel 50 is attached to the DC power supply panel 30, the power supply device will break down.

However, in the present embodiment, the power supply device is arranged so that the projecting pieces 65 and 66 are fitted into the cutout portion 35 of the first positioning portion 30A and the cutout portion 36 of the second positioning portion 30B. Therefore, only the DC power panel 30 can be attached.
Therefore, even if the remaining AC system power panel 40 or FFTU system power panel 50 is erroneously mounted, the rising portion 38 of the DC system power panel 30 is not connected to the AC system as shown in FIGS. It can hit against the surface plate 41 of the power supply panel 40 or the surface plate 51 of the FFTU power supply panel 50 to prevent insertion. At this time, the height h of the rising portion 38 is larger than the engagement depth between the connectors 32, 42, 52 and the connector 64, so that the connectors are not coupled to each other. Similarly, the protruding piece 66 provided on the surface plate 61 of the shelf 60 has the same height as the height h of the rising portion 38, so that the rising portion 38 of the DC power supply panel 30 is connected to the AC system. It hits the surface plate 41 of the power supply panel 40 or the surface plate 51 of the power supply panel 50 of the FFTU system to prevent the insertion.

Of course, erroneous replacement can be reliably prevented in the same manner when the DC power supply panel 30 on the right side of FIG. 1 is replaced.
By the way, when there is no projecting piece 65, 65, for example, it is possible to insert only the DC power supply panel 30 on the right side of FIG.
Therefore, in the present embodiment, the shape of the surface plate 31 of the DC power supply panel 30 is changed to the AC system in order to reliably prevent erroneous insertion other than the DC power supply panel 30 at the time of factory shipment or reconstruction. The positions of the DC power supply panel 30, the AC power supply panel 40, and the FFTU power supply panel 50 are not limited to the shapes of the surface plate 41 of the power supply panel 40 and the surface plate 51 of the FFTU power supply panel 50. Since the projecting pieces 65 and 66 of the shelf 60 that regulate the movement are arranged so as to fit into the notch portion 35 of the first positioning portion 30A for DC system and the notch portion 36 of the second positioning portion 30B, DC Only the power panel 30 of the system can be attached.

Next, a case where two AC power panels 40, 40 are mounted on the shelf 60 will be described.
As shown in FIG. 9, at the AC display position provided on the surface plate 61 of the shelf 60, the portions of the holes 65c and 66c of the projecting pieces 65 and 66 are arranged with the side walls 63 and 64 interposed therebetween, and screws 65b, 66b is fixed to the long holes 63a and 64a through the holes 65c and 66c. As a result, when the two AC power panels 40, 40 are mounted on the shelf 60, the projecting pieces 65, 66 have the notch portion 45 of the first positioning portion 40A and the notch portion 46 of the second positioning portion 40B. Protrusions that fit together.

Next, one AC power supply panel 40 is inserted into one side (left side in the drawing) of the opening 62 of the shelf 60. At this time, the insertion of one AC power supply panel 40 is allowed so that the rising portion 65a of the protruding piece 65 fits into the cutout portion 46 on one side. Then, like the conventional AC power supply panel, the connector 42 meshes with the connector 64 of the shelf 60, and both are coupled.
Next, the remaining AC power supply panel 40 is inserted into the other side (the right side of the drawing) of the opening 62 of the shelf 60. At this time, insertion of the remaining AC power supply panel 40 is allowed so that the rising portion 66a of the protruding piece 66 fits into the cutout portion 45 on one side. Then, like the conventional AC power supply panel, the connector 42 meshes with the connector 64 of the shelf 60, and both are coupled.

As described above, the two AC power supply panels 40 and 40 are attached to the normal position of the shelf 60 as shown in FIGS. 3, 4, 7, and 8.
Similarly to the DC power supply panel 30, the AC power supply panel 40 can reliably prevent erroneous insertion at the time of replacement.
Next, a case where two FFTU power panels 50 and 50 are mounted on the shelf 60 will be described.

  As shown in FIG. 10, the holes 65c and 66c of the projecting pieces 65 and 66 are arranged at the display positions of the FFTU system provided on the surface plate 61 of the shelf 60 with the side walls 63 and 64 interposed therebetween, and screws 65b, 66b is fixed to the long holes 63a and 64a through the holes 65c and 66c. As a result, when the two power supply panels 50, 50 of the FFTU system are mounted on the shelf 60, the projecting pieces 65, 66 have the notch portion 55 of the first positioning portion 50A and the notch portion 56 of the second positioning portion 50B. Protrusions that fit together.

  Next, one FFTU power panel 50 is inserted into one side (the left side in the drawing) of the opening 62 of the shelf 60. At this time, one FFTU-type power panel 50 is allowed to be inserted so that the rising portion 65 a of the protruding piece 65 is fitted into the cutout portion 56 on one side. The connector 52 meshes with the connector 64 of the shelf 60 and couples them together as in the conventional FFTU system power panel.

  Next, the remaining FFTU power board 50 is inserted into the other side of the opening 62 of the shelf 60 (the right side of the drawing). At this time, insertion of the remaining FFTU type power supply panel 50 is allowed such that the rising portion 66a of the protruding piece 66 is fitted into the cutout portion 55 on one side. The connector 52 meshes with the connector 64 of the shelf 60 and couples them together as in the conventional FFTU system power panel.

As described above, the two FFTU power panels 50 and 50 are attached to the normal positions of the shelf 60 as shown in FIGS. 5, 6, 7, and 8.
In the FFTU system power panel 50, similarly to the DC system power panel 30, erroneous insertion at the time of replacement can be reliably prevented.
In the above description, the replacement of the DC power supply panel 30, the AC power supply panel 40, and the FFTU power supply panel 50 has been described. However, the present embodiment is not limited to this, and for example, the DC power supply panel 30 When removing and replacing the AC system power panel 40 or FFTU system power panel 50, when removing the AC system power panel 40 and replacing it with the DC system power panel 30 or FFTU system power panel 50, the FFTU system The present invention can also be applied to the case where the power panel 50 is removed and replaced with the DC power panel 30 or the AC power panel 40. In these cases, the replacement work is performed by changing the positions of the projecting pieces 65 and 66. At this time, since the projecting pieces 65 and 66 can freely move through the long holes 63a and 64a, the projecting pieces 65 and 66 can be moved with the screws 65b and 66c of the projecting pieces 65 and 66 loosened. Since the projecting pieces 65 and 66 are screwed and the power supply panel is mounted, the fixing screws 65b and 66c of the projecting pieces 65 and 66 are not hidden and the projecting pieces 65 and 66 are not accidentally removed, which is safe. is there. In addition, when mounting power supplies with different specifications, the projecting pieces 65 and 66 can be simply slid to perform setting on the shelf side.
