For the 93PS product line, there are two different battery cabinets: EBC-S and
EBC-L. The 93PS 8-40 kW UPSs use 32 battery blocks per string.
If you connect the C-model 93PS UPS to an external battery cabinet, note
that you have to install supplementary fuses or a supplementary breaker in
addition to the internal battery breaker to ensure safe operation.
Note: Do not connect battery strings with different battery quantity and voltage
in parallel.
Power and control wiring for the EBC-S and EBC-L cabinets are supplied with
the cabinets. The battery cabinet can be located freely of the 93PS UPS
cabinet. All the wiring goes through the back wall of the UPS cabinet.
