CAUTION
The power cord and ac
transformer have a 3-wire
grounding-type plug with a
grounding pin. This is a safety
feature. Grounding of the unit 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 unit before
proceeding with the installation.
