External Service Bypass Panel and Galvanic Isolation Transformer

If both the external service bypass panel and the galvanic isolation transformer are installed, the following connections must be made:

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

•If Smart-UPS DP has an ohm load, then it is necessary to ensure the system with 20A. In this case, an external manual bypass switch which is supplied with a 32A CEE plug, should be used. The switch can ensure both 20A and 32A fuses.
