Features
Circuit Breaker (All Models)
If the current draw of the equipment connected to your model exceeds your model’s circuit breaker rating
(15 or 20 amps; see Specifications) 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 suppressor 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.
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. For service, call Tripp Lite Customer Support at (773) 869-1234. Fully
explain the perceived problem to the customer support person. They will either
remedy the problem over the phone or give you instructions about return, repair or
exchange.
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.
ISOLATED FILTER BANKS & CASCADE CIRCUITRY
(IBAR12 and ISOBAR12ULTRA Models Only)
Isolated Filter Banks prevent equipment plugged into each filter bank from interacting with equipment
plugged into the other filter bank. Cascade Circuitry provides different levels of protection between the
Isolated Filter Banks.
There are two Isolated Filter Banks on IBAR12 and ISOBAR12ULTRA models. Isolated Filter Bank #1
provides basic protection for less-sensitive or noise-producing equipment. Outlets protected on this bank
are black and can be found on the front and rear panels of these models. Isolated Filter Bank #2 provides
enhanced, or the highest level of protection for your most sensitive equipment. Outlets protected on this
bank are white and can be found on the rear panel of these models.
