AC-8CX does not power-up.
There is no power to the
connected equipment.
The GROUND OK light on the
front panel of the AC-8CX does
not light up.
The LINE OK indicator on the
front panel of the AC-8CX does
not light up.
•Check that the unit is plugged in and that there is power at the
outlet.
•Check the AC-8CX’s circuit breaker located by the power cord
and reset if necessary.
•This indicates that the wall outlet is not properly grounded or
possibly another type of line problem. Without a proper
ground, your AC-8CX will not provide power protection.
1. STOP YOUR INSTALLATION. Check the AC connection
and make sure that the AC-8CX is plugged in properly.
If the GROUND OK light still fails to illuminate, have the
AC outlet in the house checked by an electrician to diag-
nose the problem.
2. DO NOT operate your AC-8CX without a proper ground.
•This indicates that the wall outlet has a line problem such as
polarity inversion. This is common, especially in older homes.
DO NOT operate the AC-8CX with a line problem. Call your
electrician to have the line repaired.
