Phone Line Installation
®
(Isotel
Connect a phone cord directly from
1
the telephone jack to the "IN" jack of
your surge suppressor.
Your surge suppressor must be the first item in line from the
telephone jack for it to protect against surges on the phone line.
Your surge suppressor can only protect against phone line
surges if its power cord is correctly connected to a grounded,
3-wire AC outlet. It is not intended for use with network data lines.
Connect a phone cord from the device to be protected
2
to the "OUT" jack of your surge suppressor.
Select models protect TWO lines on one cable simultaneously (see specs.) If you have one of these
models and want to protect two lines that do NOT travel through one cable, you must use "Y"
splitters appropriate to your application to adapt them to your surge suppressor.
Troubleshooting
PROBLEM
Your circuit breaker trips.
Your Isobar is overloaded.
The green "Protection Present" and/
or "Line OK" LED(s) do not light.
Your equipment is not fully protected
against surges or there is a wiring
fault in your wall outlet.
The red "Fault" LED lights when you
first plug in your Isobar.
There is a wiring fault in your wall
outlet. (Phases are reversed, ground
is missing, etc.)
The red "Fault" LED lights after
continued use of your Isobar.
Your Isobar may have been damaged
by a surge.
Equipment plugged into the Isobar
exhibits audio static or video "snow".

SOLUTION
Unplug some equipment. Wait one minute
while your Isobar cools, then push the
circuit breaker button back in. (See Fig. 1)
Make sure that power is available at the
wall outlet, the power switch is on and lit,
and the Isobar is completely plugged in.
Have a qualified electrician fix the fault
immediately. NOTE: A loose wall outlet may
cause the "FAULT" LED to light. Your Isobar
will identify most wiring faults, but may not
identify every possible type of fault.
Have a qualified electrician examine your
outlet to determine if a fault has developed.
If no fault exists, contact Tripp Lite for
service.
Plug your equipment into outlets not directly
across from each other (see Fig. 2,) and
plug equipment with heavy power draws
(such as printers) into outlets away from
monitors and AV equipment.
