WARNING
Improper connection of the grounding
conductor can result in the risk of electrical
shock. The following must be observed:
• Never use a ground adapter plug to
connect the terminal to a power source
which does not have a ground
connection.
• Never attempt any maintenance function
which is not specifically called out in the
service procedures.
• Never remove any covers which are
fastened with screws, unless so
instructed in the service procedures.
CAUTION
If any of the voltage measurements are not as
specified in the following steps, the cause
must be corrected. Caution the customer not
to connect the terminal to the wall outlet.
Advise the customer that a licensed electrician
must correct the wiring. Do not attempt to
correct the wiring yourself. If you later find
the condition has not been corrected, inform
your manager in writing of the improper
wiring.
