Procedure

6-8

Connecting

the

Ethernet

cable

to

the

CSM

1

Cut

the

required

length

of

the

outdoor-rated

Category-5

Ethernet

cable

for

the

chosen

installation

site.

The

maximum

cable

length

is

100

m

(~330

ft).

2

T

erminate

the

cable

using

standard

RJ–45

connectors

using

the

procedure

as

shown

in

Figure

6-6

.

Use

dielectric

grease

(which

is

uniformly

non-conducting)

on

all

connections

and

in

all

RJ–45

Ethernet

connectors.

The

best

practice

is

to

use

enough

grease

to

fill

the

RJ–45

female

connector,

and

then

insert

the

RJ-45

male

connector

and

push

the

grease

further

into

the

unit

and

around

the

RJ–45

connector.

Excess

grease

can

be

wiped

over

the

connector

area

to

provide

some

resistance

to

water

ingress

around

the

connector.

3

W

rap

a

drip-loop

in

the

cable

at

any

point

where

the

cable

changes

direction.

4

Measure

the

cable

so

it

will

span

from

the

CSM

to

the

surge

suppressor

box.

5

F

asten

the

cable

to

the

building

according

to

local

building

codes.

NOTE

Cables

that

move

in

the

wind

can

be

damaged,

impart

vibrations

to

the

connected

device,

or

both.

A

t

installation

time,

prevent

these

problems

by

securing

all

cables

with

cable

ties,

cleats,

or

weather

resistant

tape.

The

cable

can

be

a

path

for

water

to

follow

to

enter

the

cable

connector

or

even

the

module.

Prevent

this

problem

by

including

and

securing

a

drip

loop

where

the

cable

enters

the

building.
