Step
Ensure that wiring to the
2
Power Supply is
disconnected from the site
source, and then connect
AC wiring to the power
supply as shown at right.
Note: The Yellow/Green
wire is supplied with the
power supply. The nuts
(w/star washers) for the
grounding stud are on the
stud. The power supply
has an internal fuse that is
not replaceable. A second
external fuse may be
added if desired. For P01
power supply use 3.0A,
slow-blow for 115VAC
operation; 2.5A, slow-blow
for 230VAC operation. For
P02 power supply, use
2.5A, slow-blow for
115VAC operation; 2.0A,
slow-blow for 230VAC
operation. For P24 power
supply use 7.0A slow-
blow.
CAUTION
The P24 is a +24V DC
Power supply. Do not
apply AC voltages of any
kind to this power
supply or you will
destroy it.
Apply power. For P01
only, test voltages at the
test points provided on the
face of the Power Supply.
Note: Test-points are
electrically connected to
the backplane of the rack.
If the power supply is not
properly seated in the
backplane connectors, no
voltage will be measured
at the test points.
