The safety earth cable must be connected to the earth bus bar and bonded to each cabinet in the system.
All cabinets should be earthed in accordance with local regulations.
The UPS itself has no effect on the earthing quality i.e. it doesn’t change the unwanted voltage difference
between the earth and neutral lines.
Once the equipment has been finally positioned and secured, connect the power cables as described in
the following section.
It is recommended that the UPS should be connected to the line voltage protected by a circuit breaker.
