Optional Equipment Installation

Galvanic Isolation Transformer

The galvanic isolation transformer can be delivered for one- or two-phase connection. When connecting a Smart-UPS DP and galvanic isolation transformer, the AC bus and the wires for the thermo switch must be mounted. Please follow the instructions below.

Note:

If the cables in the galvanic isolation transformer have 4 wires, the wire marked no. 3 must be cut off.

Galvanic Isolation Transformer Connections

The AC bus from the galvanic isolation transformer must be mounted.

Note:

If the galvanic isolation module is installed it must be secured so that the neutral is grounded according to local regulations.

This is done in the galvanic isolation transformer with a wire between terminal 5 (PE) and 9 (neutral).

This wire is already mounted from the factory. If the Smart-UPS DP has to be grounded to a separate EDP earth, this is done

to terminal 9, after having removed the wire between terminals 5 and 9.
