Add, Remove, or Replace a Power Module

NOTE: The power module can be replaced when the UPS is in any operation mode.

NOTE: Install power modules starting with the bottom positions and upward.

WARNING
RISK OF EQUIPMENT DAMAGE Before installing a new power module, check the upstream and downstream protection configuration first. Make sure your UPS is configured correctly for the upgraded frame rating. For example, if your UPS is upgraded from 200 kW to 250 kW, the choice of breaker type must be based on the rating of 250 kW. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Only for UPSs with redundant intelligence module: From the main menu, select Maintenance > Redundant IM > PM/SBS removal request. Click OK on the confirmation screen.
Remove a power module:
1. Set the enable switch on the power module to the OFF position.
2. Remove the screws in the sides of the power module.
3. Pull the power module halfway out. A locking mechanism prevents the power module from being pulled all the way out. Release the lock by pressing the release button on the left side of the power module.
4. Remove the power module.
5. If no replacement power module will be installed: Install a filler plate in front of the empty power module slot.
6. From the main menu, select Status > Power modules. Tap the power module icon that corresponds to your removed power module and click Confirm disconnect.
  
  NOTE: This step is only required for removing a power module but not required for installing/adding a power module.

Install/Add a new power module:

Remove the filler plate from the empty power module slot. Save the filler plate for future use.
Push the power module into the slot.
Reinstall the screws in the sides of the power module.
