Electrical Installation Guidelines
Power Line Connections
Refer to Table 3-1. This unit is designed to
accommodate a broad range of power line voltages
for both 50 and 60 Hz found around the world. The
power line input is three phase, and the
transformer taps must be changed to select the
operating voltage range. The power supplies are
designed to operate at
+

-
10% of the normal
voltage for a given tap setting. Only the taps on the
two identical power transformers need to be
changed.

Power Source
The customer power source must be wired in
accordance with either the National Electric Code,
Part I or the Canadian Electrical Code, Part I, or
local codes.
Connector P1 on the power supply is for
three-phase input power. A 600 Vac, 30 Amp twist
lock connector is supplied with the system for the
power input.
Measure the incoming power source voltage from
the main power supply. Make sure that the power
source voltage matches the transformer tap
settings.
