4. Plug the power transformer output connectors into
the P19 and P20 connectors on the backplane and
latch them.
CAUTION
The power cord contains a
3-wire grounding-type plug
which has a grounding pin.
This is a safety feature.
Grounding of the carrier is
vital to ensure safe operation.
Do not defeat the purpose of
the grounding plug by
modifying it or by using an
adapter.
Prior to installation, use an
outlet tester or voltmeter to
check the ac receptacle for
earth ground. If the power
source does not provide a
ground connection, consult an
electrician to determine
another method of grounding
the carrier before proceeding
with the installation.
