5.336 – 24/30/36kVA

Ensure the AC supplies and load are switched OFF. Check that all the EDP70 PLUS UPS Switches (behind the front panel) are switched OFF, see figure 13.

The AC supply cables must be suitable for carrying the maximum supply demand. The voltage drop in the cable should be minimized to ensure the AC supply voltage at the EDP70 PLUS UPS terminals is within +/- 10% of nominal.

The EDP70 PLUS UPS should be connected to the main/reserve supplies and output load via a wall mounted junction box.

Installation and connection should only be carried out by qualified electrical personnel.
