SPECIAL CONSIDERATIONS FOR 1-PHASE OUTPUT

This section discusses some special considerations for Power+ UPS System single-phase
output (3/1 and 1/1 configuration).
4.5.1

DIP-SWITCH SETTINGS ON THE MODULES

1. On the left side of each module, close to the front panel is a small window with access to
three dip-switches.
2. For standard three-phase input and output (3/3 configuration) dip-switch no. 3 is set to
ON(LEFT) position.
3. For single-phase output (3/1 or 1/1 configuration) set the dip-switch no. 3 to OFF(RIGHT)
position on all of the modules of the System.
4.5.2

WIRING OF INPUT AND OUTPUT TERMINALS

1. For 3/1 configuration (Three phase input and single-phase output) the Bypass AC input
terminals R,S&T must be shorted between them with 35mm² wiring and so must be the
AC output terminals R,S&T.
2. For 1/1 configuration (Single-phase input & output) The UPS (Rectifier) AC input
terminals R, S & T must also be shorted between them.
3. Illustrations of 3/3 3/1 and 1/1 External wiring configurations are presented in attached
files.
