Observe

caution

when

drilling

through

the

Ensure

that

there

are

no

power

lines,

Surge

suppressor

installation

and

cable

connections

1

A

ttach

the

surge

suppressor

to

the

communication

hut

near

the

cable

access

point

to

the

inside

of

the

communications

hut

using

two

screws.

2

Remove

the

surge

suppressor

front

cover

to

access

the

Ethernet

RJ-45

jacks.

3

Connect

the

Ethernet

cable

from

the

CMM4

to

the

Ethernet

port

on

the

surge

suppressor

port.

CAUT

I

ON

Follow

local

building

codes

for

penetrating

buildings.

Observe

caution

when

drilling

through

the

wall

of

the

building.

Ensure

that

there

are

no

power

lines,

gas

lines,

water

lines,

or

data

lines

in

the

wall

at

the

desired

location.

Drill

a

3/4

inch

(18

mm)

hole

through

the

wall

of

the

communications

hut

at

the

desired

location.

5

Connect

the

Ethernet

cable

from

the

network

or

switch

router

from

the

communications

hut

to

the

Ethernet

port

on

the

600S

SD

surge

suppressor

.

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.

7

Ground

the

surge

suppressor

to

Earth

Ground.

8

Install

the

surge

suppressor

front

cover

to

the

base

of

the

unit

ensuring

that

the

cables

are

all

routed

through

the

cable

slots.
