Install the Power Module(s)

NOTE: The power module must be in Off mode.

NOTE: One 50 kW power module is preinstalled in the UPS. Additional power modules are shipped separately for UPS ratings over 50 kW and must be installed to reach the correct UPS kW rating.

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.
