Figure 2.6e2: UPS terminal block in three phase/single phase configuration (Whit input and reserve
separate).
If not required, the UPS is supplied with mains and reserve line in parallel (Fig.2.6c). It is possible to
separate them by removing the connecting bars.
Before connecting the UPS it is necessary to:
- make sure that the mains voltage and frequency match those indicated on the adhesive plate located on
the rear side of the UPS (input voltage, operating frequency, etc.);
- make sure that the earth connection of the system fully complies with the requirements of IEC standards
or local laws.
After that install four pole circuit breakers upstream and downstream from the UPS with the following
specifications:
- rating equal or greater than what is indicated on the label on the UPS rear (kVA);
- specifications in compliance with IEC standards or local laws for “Curve C” circuit breakers.
