Niles Audio AC-8CX - Manual (Page 10)

When illuminated, the Ground OK LED on the AC-8CX indicates that the house wiring is proper-
ly grounded. If the LED does not illuminate, there is a line problem. Without a proper ground, your
AC-8CX will not be able to provide protection from electrical surges and spikes. DO NOT OPER-
ATE YOUR AC-8CX WITHOUT A PROPER GROUND. IF THE GROUND OK LED DOES NOT
ILLUMINATE, DISCONNECT THE UNIT IMMEDIATELY.
When illuminated, the LINE OK LED on the AC-8CX indicates that the wall outlet does not have a
line problem such as polarity inversion. If the LED does not illuminate, there is a line problem. This
is common, especially in older homes. Call your electrician to have the line repaired. DO NOT
OPERATE YOUR AC-8CX WITH A LINE PROBLEM. IF THE LINE OK LED DOES NOT
ILLUMINATE, DISCONNECT THE UNIT IMMEDIATELY.
The Switched LED on the AC-8CX illuminates when the Power Button is activated indicating that the
Switched outlets are ON. When the Power Button is not initiated, the Switched LED does not illumi-
nate, indicating that there is no power at the Switched Outlets.
