In contrast, when dismounting, insert the screwdriver front end in hole that near the retainer of terminal board housing, is provided with or the ditch, the plastic deformation (elasticity) that utilizes the wall of terminal board housing is after the chimeric status of the retainer of removing a side, and disassembling section just finishes after the empty-handed releasing of the chimeric status of the opposing party's retainer.
So, because the fitting operation of this terminal lid cover is functional, need not special tool(s) and just can carry out disassembling section, we can say that its production is good self-evident, its service is also very excellent.
In addition; even because the lead that multiple Starting mode, multiple control mode is arranged on the terminal board connects with tenminal block not enough; owing to can directly connect the line on the tenminal block of starting drive or overload protection arrangement; with this lead by being arranged at after slotted hole on the terminal board is drawn out to the outside; utilize wire clamp to fix, so a power supply unit can corresponding all purposes.
As a result, there is no need to distinguish the power supply unit which kind of uses, both can prevent the production line confusion that the mistake assembling causes in advance, also can receive because of in rationalizing the effect that waits effect economically that the producibility raising is produced not count.
In addition, with the IEC conformance to standard, and when making device according to its application target become the device of cheapness of miniaturization and, can provide the device of reliability, excellent in safety simple and easyly.
