Do not press any remote EPO button.

Operating Procedures

7.Press the EPO (Emergency Power Off) button at the UPS front panel of this UPS module only. This will disable further Rectifier, Inverter, Static Switch and Battery operation. This will not affect the manual maintenance bypass power switch.

NOTE

Do not press any remote EPO button.

8.Open the Rectifier input power switch Q1 and Static bypass input power switch Q2

9.When an external battery is connected, open external battery circuit breaker. This breaker is located inside the battery cabinet (if used) or is otherwise adjacent to the battery racks

All mimic panel LED indications and messages will extinguish as the mains driven internal power supplies decay.

The load is now powered from the maintenance bypass supply and the UPS is completely shut down.

! WARNING

Hazardous Voltage at UPS terminals

No operator-serviceable parts are located behind covers that require a tool for their removal. Only qualified service personnel are authorised to remove such covers.

The input and output AC and DC battery and connecting terminals remains energized at hazardous voltage levels at all times. The battery is located behind protective covers that require a tool for their removal. inside the UPS cabinet (30 and 40kVA models), inside a free- standing battery cabinet or on open racks inside a dedicated battery room that may be locked.
