Circuit Breaker (All Models)
If the current draw of the equipment connected to your model exceeds your model’s circuit
breaker rating for longer than a few seconds, the circuit breaker will trip to prevent any
possible damage. When the circuit breaker trips, its plunger will be extended. Remove excess
equipment and allow the breaker to cool one minute before depressing its plunger to reset
the breaker.
Illuminated “On/Off” Switch (All Models)
When your model is plugged into an AC outlet providing power of appropriate voltage and
frequency (see Specifications), this switch will illuminate RED when moved to the “ON”
position. This indicates 120V AC power is present at the model’s AC receptacles.
Diagnostic Indicator Lights (ISOBAR Models Only)
When your surge protector is plugged into an AC outlet providing power of appropriate
voltage and frequency (see Specifications), the three LEDs on the front panel show current
power conditions as follows, from left to right across the front of the unit:
Line “OK” (Green LED): Indicates that nominal AC power is present with no wiring faults
detected. When this LED is illuminated, AC power is safe for connected equipment.
Line Fault (Red LED): Indicates a wiring fault has been detected. If this LED illuminates at
any time 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 ISOBAR is plugged into. The Line Fault
detector circuitry will identify most common wiring faults, but will not necessarily detect
every possible type of fault.
Features
If the Line Fault indicator light illuminates, carefully check the AC receptacle the
ISOBAR is plugged into. The receptacle must be tight and securely grounded. A
loose AC receptacle may cause the Line Fault LED to illuminate. It must be
understood that this Red LED indicates the presence of a wiring fault, but does
not indicate the exact nature of the fault. Therefore, a qualified electrician
should make necessary repairs.
If the Line Fault indicator light illuminates and power is not present at the
outlets, the ISOBAR’s surge-suppression components have been compromised as
a result of surge damage.
Protection Present (Green LED)*: Indicates the surge-suppression components are
intact and providing full protection against spikes and surges. This LED should be lit anytime
the ISOBAR “ON/OFF” switch is turned ON and power is present, as indicated by the lighted
power switch. If the Protection Present LED does not light, then some of the surge
suppression components are not functioning and the unit should be returned for repair as
soon as possible. You may still use the unit; however, connected equipment will be
protected from spikes and surges at a lesser level than normal.
* Feature also available on the DRS-1215 model.
