Power Module
The Power Module maintains the condition of
power in the S5K Modular UPS. Each module is
an independent 4 kVA unit, consisting of a power
factor corrected rectifier, battery charger and
inverter, with associated monitoring and control
circuitry. The modules are paralleled to provide
greater capacity and/or redundancy. Modules may
be added or replaced on-line with no interruption
or danger to the connected equipment.
Battery Module
The Battery Modules provide backup power in the
event of input utility failure. Each module contains
10 individual 12-volt, valve-regulated (VRLA)
battery blocks with associated monitoring and
controls to isolate the Battery Module in the event
of a battery failure. The modules are paralleled to
provide greater capacity, backup time and/or
redundancy. Modules may be added or replaced
on-line with no interruption or danger to the
connected equipment, provided that the UPS is
not operating on battery.
Under normal operation, the Status LED (green) will blink and the Fault LED (amber) will be off. For any
condition other than this, check the
Troubleshooting section starting on page 35.
