6.0 Terminal Grounding

Fasten a #6 AWG wire to the ground bar which is
located on the front of the unit.  Connect other end
of ground wire to local ground per company
standards.

Note:

Failure to properly bond and ground the
terminal per N.E.C. or local equivalent codes
may render protection arrestors useless.

3.0 Protector Specifications

To maintain UL Listing, only five pin protectors
that are UL Recognized or Listed can be used.

2.0 Accessories

2.01 Protective Covers  -  These hinged cover kits

provide mechanical protection of the protector
receptacle field, modular hardwire and Self Strip
blocks.  A hasp is included if a padlock is
employed for added security.  Models available
are:  4372-25; 4372-50; 4372-100; 4373-25;
4373-50; 4373-100.

2.02 4187 Extension Stubs  -  The extension stub is

a 25' (7.6 m) 26 AWG Alvyn cable,
preconnectorized on one end with a modular
connector base.  The stub can be crimped to the
preconnectorized short stub to provide an
extension to the entrance cable.  They are
available in 25, 50 and 100-pair sizes.

2.03 4327 SS Pair Probe  -  The 4327 SS Pair Probe

provides electrical access to a pair of 4320 Self
Strip contacts.

2.04 4347 Pair Test Clip  -  The 4347 Pair Test Clip

allows for test connections to be made to both Tip
and Ring binding post screw washers
simultaneously on all types of 3M brand Modular
Hardwire Blocks.

5.0 Terminal Locations

5.01 Locate terminal according to standard operating

procedures.  Consider the following points as
much as possible:

a. Locate terminal inside building as close as

possible to cable entrance.

b. Locate terminal on a firm mounting surface

where it will be accessible to the technicians at
all times; where it can be reached without a
ladder; and where it will not project in a
hazardous manner.

CAUTION: Avoid locations near flammable

materials, ignitable gases, dust,
moisture, temperature extremes,
moving machinery, electric light and
power circuits, and electrical equipment.

c. Observe caution when exposing terminal to

chemicals in liquid or vapor form as they may
damage the plastic components.

5.02 Open the splicing chamber by removing the two screws

on the right-hand side of chamber door.  Reinsert
screws in tapped holes to avoid losing screws.

5.03 Pull the preterminated short stub, insulated ground

wire, and accessories out of the splicing chamber.

5.04 Tape the mounting template to the designated

position and mark screw locations (3).  Remove
mounting template.

5.05 Mount the terminal in designated position with the

three mounting screws provided.

5.06 Remove jumper wire retaining rings from poly bag

and install in face plate.
