American Power Conversion PX user manual Redundant Intelligence Module Replacement

Chapter 8 - Module Replacement

Main Intelligence Module Replacement

1.Remove the grill cover from the top level of the Power Array. The intelligence module resides under the redundant intelligence module in the upper right corner of the frame.

Note: If a functioning RIM is installed, it will provide limited control of the SymmetraTM until the replacement MIM is installed. If a functioning RIM is not installed, either the SymmetraTM must be placed in manual bypass mode or the load equipment must be switched off. To place the SymmetraTM in manual bypass, switch the maintenance bypass switch to the “on” position.

Important: When the SymmetraTM is in bypass mode, the load equipment is unprotected from power failure.

2.Use a flathead screwdriver to release the flip latch.

3.Unscrew and release the retaining screws.

4.Slide the MIM out of the frame.

Installing the Replacement Main Intelligence Module

Refer to Chapter 5 for the MIM installation procedure.

Note: If SymmetraTM was placed in manual bypass in step 1 above, return to normal operation by switching the maintenance bypass switch back to the “off” position.
