TRANSMITTER

 

INSTALLATION

 

The

 

GTC116

 

transmitter

 

is

 

designed

 

for

 

use

 

in

 

an

 

environment

 

between

 ‐

20°

 

F

 

to

 

120°

 

F

 

(

28.8°

 

C

 

to

 

48.8°

 

C)

 

where

 

it

 

will

 

not

 

be

 

exposed

 

to

 

rain

 

or

 

snow.

 

Install

 

transmitter

 

upright

 

and

 

in

 

a

 

field

 

accessible

 

location.

 

The

 

enclosure

 

accepts

 

1/2

 

in.

 

(12.7

 

mm)

 

electrical

 

fittings

 

for

 

signal

 

and

 

power

 

wiring

 

at

 

both

 

sides

 

at

 

the

 

top

 

of

 

the

 

enclosure.

 

Locate

 

the

 

transmitter

 

so

 

that

 

the

 

connecting

 

cables

 

from

 

all

 

of

 

the

 

sensor

 

probes

 

will

 

reach

 

the

 

receptacles

 

on

 

the

 

bottom

 

of

 

the

 

transmitter

 

enclosure.

 

In

 

locations

 

exposed

 

to

 

direct

 

rain

 

and/or

 

snow,

 

the

 

transmitter

 

must

 

be

 

enclosed

 

in

 

a

 

NEMA4

 

enclosure.

 

Leave

 

unobstructed

 

space

 

of

 

at

 

least

 

9

 

in.

 

(228.6

 

mm)

 

above,

 

2

 

in.

 

(50.8

 

mm)

 

to

 

each

 

side

 

and

 

3.5

 

in.

 

(88.9

 

mm)

 

below

 

the

 

transmitter

 

to

 

allow

 

for

 

cover

 

removal,

 

sensor

 

connections

 

and

 

heat

 

dissipation.

 

Locate

 

the

 

transmitter

 

in

 

a

 

location

 

that

 

can

 

be

 

reached

 

by

 

all

 

connecting

 

cables

 

from

 

the

 

sensor

 

probes.

 

Do

 

not

 

drill

 

into

 

the

 

transmitter

 

enclosure

 

since

 

metal

 

shavings

 

could

 

damage

 

the

 

electronics.
