Circuit Breaker
If the current draw of the equipment connected to the surge suppressor exceeds 15 amps
for longer than a few seconds, the circuit breaker will open (trip) to prevent any possible
damage. When the circuit breaker trips, the plunger will be extended. Remove the overload
and allow the breaker to cool for one minute before depressing the plunger to reset.
Static Discharge
It is recommended that you touch your Under-Monitor Surge Suppressor before starting work
at your computer. This will safely dissipate static that can damage sensitive electronic cir-
cuitry. Follow the simple procedure outlined below for your model:
( ( T T o o u u c c h h M M a a s s t t e e r r , , T T o o u u c c h h M M a a s s t t e e r r P P L L U U S S ) ) : touch the shiny metal plate on the right side of the
front panel.
( ( P P o o w w e e r r C C e e n n t t e e r r , , C C o o m m m m a a n n d d C C o o n n s s o o l l e e , , C C o o m m m m a a n n d d C C o o n n s s o o l l e e P P L L U U S S ) ) : touch any metal part of
the cabinet.
Diagnostic Indicator Lights
There are up to four LEDs on the front panel that indicate various operating parameters
when the unit is plugged into a live 120V AC/60 Hz outlet.
• • PROTECTION PRESENT (Green Indicator Light) (all models)
Indicates the surge suppression components are intact and providing full protection
against spikes and surges. This LED should be illuminated anytime the MASTER switch
is turned ON and power is present as indicated by one of the following:
(T T o o u u c c h h M M a a s s t t e e r r , , T T o o u u c c h h M M a a s s t t e e r r P P L L U U S S ): Green Indicator Light above the MASTER switch is
illuminated.
(C C o o m m m m a a n n d d C C o o n n s s o o l l e e , , C C o o m m m m a a n n d d C C o o n n s s o o l l e e P P L L U U S S , , P P o o w w e e r r C C e e n n t t e e r r ): MASTER switch is illuminated.
(C C o o m m m m a a n n d d C C o o n n s s o o l l e e C C o o m m p p a a c c t t ): Red Indicator Light below MASTER switch is illuminated.
If the Protection Present LED does not illuminate, then some of the surge suppression
components are not functioning, and the unit should be returned for repair. You may still
use the unit. However, connected equipment will be protected from spikes and surges
at a lesser level than normal.
• • LINE FAULT (Red Indicator Light) (all models except Power Center)
Indicates a wiring fault has been detected. If this LED illuminates at anytime the unit is
plugged in, the fault should be repaired by a qualified electrician as soon as possible. This
LED indicates that phases are reversed, ground is missing or some other sort of wiring
error exists in the circuit the Under-Monitor Surge Suppressor is plugged into. The Line
Fault detector circuitry will identify most common wiring faults, but will not necessarily
detect every possible type of fault.
