EOS 90401-A-PHY-0006-PDU Basic Power On

6. Configure the primary voltages for the isolation transformer

a. There are 3 different sets of jumpers
included with the isolation transformer.
Which set will be used, is based on the

existing Mains power supplied in the
country/region where the equipment is
being installed. There is one “jumper” per
electrical phase which will need to be
configured at the primary side of the

transformer labelled: U1, W1 or V1.

Before starting this part,
ensure that cables are de-
energised. POWER OFF!

b. Here are the 3 different types of

Connecting Comb (Jumper links) for the
primary of isolation transformer. Each
represents a different power level: 380V, Figure 1 - Isolation Transformer
400V and 480V (see picture).
