Figure 12: Surge arrestor Neutral, for “4-wire + Ground” infrastructure

Attention: There is a surge arrestor at the rear of the UPS. It is normally hidden

by a large metal panel (see Figure 12).

When connecting the UPS to a “4-wire + Ground” infrastructure, disconnect the

blue wire from the grey terminal that is next to the surge arrestor, and connect

the wire to the Neutral point of the surge arrestor.
