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

other
energy storage means, a
certified
service technician
should be
consulted

proceeding
with
installation.

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.
