1.3.4 Repair Service
All warranty repairs are performed at no cost. Positron reserves the right to repair
or replace any equipment that has been found to be defective.
For information about out-of-warranty repairs, contact Positron’s Repair
Department. Due to the varied nature of repairs, no specific turnaround can be
guaranteed, but average turnaround time is 20 working days from date of receipt.
In emergency situations, special arrangements can be made. All repaired items
are warranted for a period of 90 days.
Before returning any items to Positron for repair, warranty repair or replacement,
call the Repair department to obtain a Return Material Authorization (RMA)
number. Parts returned without RMA numbers cannot be accepted. The RMA
number must always be clearly marked on all boxes, crates, and shipping
documents. Bulk repairs (more than five items) will require additional processing
time, so please take this into consideration when requesting an RMA number.
To accelerate the repair process, whenever possible, include a report detailing the
reason for return with the unit(s). Also, please include the name and phone
number of a person who can be contacted should our Repair department need
further information.
When packing items being returned for repair, please ensure they are properly
packed to avoid further damage. Plug-in cards should never be shipped while
installed in a shelf; this will cause damage that can extend the repair period.

Non-Fragmenting Lightning Arrestor Unit model 751126/1
2.1 Introduction
The Teleline Non-Fragmenting Lightning Arrestor Unit with See-Through Door
model 751126/1 guards against the very high potential difference that may
develop between a Central Office (CO) incoming cable sheath and station ground
due to a lightning strike or Ground Potential Rise (GPR). In the event of an over
voltage, the arrestor limits the voltage between the sheath and station ground to
its breakdown voltage.
The unit consists of the non-fragmenting lightning arrestor, in a small, compact
enclosure. The enclosure is molded from fiberglass, making it a lightweight, flame
retardant product of high dielectric strength. Its fiberglass body limits the
possibility of many kinds of infiltration (of dust, mist, and water from sprinklers)
while providing reliable isolation from external ground potentials.
The unit’s scratch-resistant polycarbonate window allows easy assessment of the
arrestor’s state. In the event of an arrestor failure, the core’s polymer housing
does not fragment as a porcelain housing would, resulting in less danger to
adjacent personnel and equipment.
The unit is lightweight, and installs easily between the CO incoming cable and a
Teleline Isolator shelf (or shelves).The unit is a 15 kV arrestor and is
recommended where the incoming cable is a Polyolefin Insulated Cable (PIC)
having a high breakdown voltage.
For a view of the Non-Fragmenting Lightning Arrestor Unit, refer to Figure 1 on
page 15.
QThe lightning arrestor unit is intended to complement the protection
provided by Teleline Isolator shelves by preventing surge voltages from
rising higher than the rated voltage of the Teleline modules. Positron
strongly recommends that a lightning arrestor be used on every
incoming CO cable.
