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.
