Installing touch guards and closing covers

All modules of the application inverter are equipped with touch guards [1] and the first and last modules of the axis system have closing covers [2]; see the following figure. If the axis system contains a master module, the closing cover [2] must be attached only to the final module in the axis system.

For the MDP92A-.. power supply module, connector X1 and for the DC/DC converter MDE90A-.., connector X12 must always be plugged in and screwed tightly. These connectors are part of the protection against accidental contact that is necessary to achieve IP20 degree of protection.
