INSTALLATION NOTE

1. GENERAL

The TII 126 and 127 Series Station Protectors

modules may be installed in a wide variety of station

protector and network interface housings. They may

also be used as indoor station protectors when

attached to a TII B1 Mounting Adapter.

The modules are self clearing and generally require no

maintenance. Because the wiring terminals are an

integral part of the protector module, the entire self-

contained unit must be removed and replaced when it

reaches its “end of life” condition

It is possible that successive operations or the

cumulative effect of heat may cause failure of the gas

tube. In case of trouble, the entire protector module

should be replaced with a new module.

National Electric Code Requirement. The protector

shall be installed per National Electric Code

ANSI/NFPA 70, Article 800, Section C, and shall meet

all applicable local safety codes.

These modules shall be installed in NID

enclosures evaluated to the requirement of UL497.

2. INSTALLATION – Station Protector or NID

Loosen the nut on the appropriate ground stud.

Slide the surge protector ground clip of under the nut

and washer. Tighten down the nut (Figure 1).

Ground the module using a No. 6 AWG solid copper

insulated ground wire. Connect one end of the ground

conductor to the appropriate ground stud and the other

end to an appropriate ground source (Figure 1).

Terminate the Telco Side cable (i.e., aerial or buried

drop) in between the bottom set of washers and

bottom nut of the appropriate stud (one conductor to

Tip and one to Ring). Tighten down the nut (Figure 2).

Terminate the Customer Side cable under the top set

of washers and the top nut of the appropriate stud

(one conductor to Tip and one to Ring). Tighten down

the nut (Figure 2).

Loop back unused station wire conductors and coil

around the station wire jacket or store in such a

manner as to prevent them from coming in contact

with protector terminals or bare wires.

When more than one cable is placed under a nut, use

washers between the wires.

Use caution when terminating small gauge Customer

Side cable on the protector module terminals, as the

wires may catch in the threads of the terminal and be

cut or broken when nuts are tightened.

Check all nuts to make sure they are tight.

3. PRECAUTIONS

When clearing trouble on a line that contains gas tube

protector modules, and when the test board has

indicated that there may still be a power contact,

inspect the non-cable portion of the line from the

ground for any power contacts or evidence of damage

from power contacts.

Special care should be taken in making the

inspections where the line runs through trees or where

visibility is limited.

If a power contact is found, notify the proper authority

so it may be corrected.

Do not work on the line until the power contact has

been cleared.

If no contact is found but the test board still have

indications of a power contact, wear insulating gloves

while working with the test board to clear the line.
