2. Important Safety Warnings
• When installing the unit, verify that any maintenance bypass panel used is configured correctly before applying power to the unit.
• Be sure to place a warning label on all primary power isolators installed remotely from the UPS area and on any external access points
between such isolators and the UPS. The warning label shall carry the following wording or equivalent.
Before working on this circuit
- Isolate Uninterruptible Power System (UPS)
- Then check for Hazardous Voltage between all terminals
including the protective earth.
Risk of Voltage Backfeed
2.8 Operation
Do not disconnect the earth conductor cable on the UPS or the building wiring terminals at any time, as this will cancel the protective
earth of the UPS system.
In order to fully disconnect the UPS system, first press the “OFF” button, then disconnect the mains.
Ensure no liquid or other foreign objects can enter into the UPS system.
