Communication Cable Kit

A CAT 5 cable provides the RS 485

communications link between the SC 370

designated as System 1 and all subordinate

units installed in the system. Two

connections at J4 on PCB1 allow multiple

units to be daisy chained together. Either

port may be utilized as an input to or

output from PCB 1.

The required number of Communication

Cable Kits (P/N 4362039) is supplied with

each complete SC 370 system. Each kit

consists of a cable and two strain relief

connectors with inserts for the cable. One

strain relief is to be installed in System 1

and the other in System 2. Follow the

method below for routing the cable if

flexible conduit is not utilized for the

installation.

1. Install the ¾” cable strain relief on the

enclosure.

2. Slide the dome nut over the cable.

3. Install the connector insert over the

cable with tapered end facing away

from the connector.

4. Push the connector through the

housing from outside the enclosure.

5. Push the cable insert into the strain

relief housing.

6. Plug the cable into PCB1 and position

the cable, providing a small amount of

slack inside the cabinet to reduce stress

on the connector. Coil excess cable

equally between enclosures. Do not

cut and splice to remove excess cable.

7. Tighten the strain relief connector

dome nut.

8. Repeat steps 1-7 to connect additional

SC 370 units (3-6).

WiFi Option Antenna Installation

All internal components of the optional

WiFi access point are factory installed.

The antenna must be installed after the SC

370 is mounted. The following

instructions are provided to mount the

antenna to the SC 370 enclosure using the

supplied hardware kit. Figure 2-3

provides a pictorial of the installation.

Connection to the WiFi access point is

discussed in Section 4.

1. Locate the following items supplied

with the SC 370 system:

 WiFi Antenna (P/N 5905231)

 Shielded CAT 5 Cable 6’ (P/N

4362028)

 Antenna Mounting Kit (P/N 1370191)

o Conduit Hub with lock ring

o Conduit Nipple 0.75” x 12”

o Coupling

o Cable Strain Relief

o Custom Insert (Cable Strain

Relief)

o (2) Adjustable Clamp 1 1/16” – 2”

2. Attach the conduit hub to one end of

the 12” nipple and the coupling to the

other end.

3. Screw the strain relief into the

coupling.

4. Locate and remove the access cover

from the back of the WiFi antenna.

Remove the knockout that is located

below the ground terminal.

5. Center the WiFi antenna on the

conduit assembly and attach using the

two adjustable clamps. The top of the

WiFi antenna must be located nearest

the conduit hub.

6. Locate an available 0.88” hole on the

SC 370C unit and install the antenna

assembly. See Figure 2-8 for the SC

370 hole configuration.

7. Connect the CAT 5 cable to the RJ 45

connector located on the WiFi antenna.

Route the other end of the CAT 5

cable through the strain relief and into

the SC 370. Leave a small drip loop

between the antenna and the conduit

assembly.

8. Route the CAT 5 cable to the Power

Over Ethernet (POE) Injector and

connect to the terminal labeled “POE”.

9. Install a ground wire (8 AWG

recommended) from the antenna

ground terminal to the site ground.

10. Replace the access cover.
