MODES OF OPERATION
The S5K Modular UPS is designed to operate as a true on-line system in the following modes:
Normal Mode
The Power Module rectifiers derive power from a
utility AC source and supply regulated DC power to
the inverter. The module’s inverter regenerates
precise AC power to supply the connected
equipment. The battery charger maintains a float-
charge on the battery.
Backup Mode
When AC utility fails, the connected equipment is
supplied power by the inverter, which obtains
energy from the Battery Modules. The output
power equipment will not be interrupted during the
failure or restoration of the AC utility source.
Auto Restart Mode
After a power outage and complete battery
discharge, once AC utility is restored, the UPS will
automatically restart and resume supplying power to
connected equipment. This feature is enabled at the
factory, but can be disabled by the user. The user
can also program two auto restart delay settings:
1. Battery capacity level (%)
2. Countdown timer
Recharge Mode
When AC utility is restored, the unit will
automatically recharge the Battery Modules until
they are fully charged.
Bypass Mode
The bypass provides an alternate path for power to
the connected equipment and operates in the
following manner:
• Automatic
In the event of an internal fault or should the
inverter overload capacity be exceeded, the
UPS performs an automatic transfer of the
connected equipment from the inverter to the
bypass source.
• Manual
Should the UPS need to be taken out of ser-
vice for limited maintenance or repair, manual
activation of the bypass will cause an immedi-
ate transfer of the equipment from the inverter
to the bypass source.
