2 Installation
The battery system provides emergency short-term backup power to safeguard operation during
brownouts, blackouts, and other power interruptions. By default, 93PM and 93E UPSs are
configured to use valve-regulated lead-acid (VRLA) batteries. For the battery specification, see
UPS User’s and Installation Guide. Should there be a need to connect other type of batteries or
other energy storage means, a certified service technician should be consulted prior to
proceeding with installation.
For the 93PM and 93E product lines, there are two different battery cabinets: Small and Large
Battery Cabinet. The battery block configuration in the chosen battery cabinet must always match
the UPS requirement. Used battery configuration must be inserted into UPS settings during
commissioning or start-up. Refer to UPS installation and operation manual for UPS configuration.
The allowed battery block configurations for 93PM and 93E UPSs are presented in table 2-1.
