RL-854 Radio Control Unit

 

Type I, Style A

Installation

Installing Standard RL-854

3. Route power to the unit.

(contd.)

NOTE: This must meet the National Electric Code (NEC) and/or any

 

 

local codes. One of the two 1 in. (25.4 mm) bottom wire entrance holes

 

may be used for this purpose.

 

4. See Figure 2. Connect 120 V ac to terminal TB1 as follows:

 

a) Black wire to line (L) terminal

 

b) White wire to neutral (N) terminal

 

c) Green wire to ground (G) terminal

 

5. Connect the circuits to be controlled to terminal block TB2 terminal 1

 

through 6 (as required) as follows:

 

a) Terminal 1 connects to terminal 2 when 3-pulse relay is powered.

 

b) Terminal 3 connects to terminal 4 when 5-pulse relay is powered.

 

c) Terminal 5 connects to terminal 6 when 7-pulse relay is powered.

 

NOTE: These contacts have only a light-duty current-carrying

 

capacity.

 

6. Connect the antenna plug attached to the antenna lead-in wire to the

 

receptacle on the radio unit. Route the antenna cable to the antenna

 

location.

 

NOTE: Avoid sharp bends in the antenna cable, and leave a drip loop

 

anywhere the antenna lead-in wire changes from vertical to horizontal.

 

Be sure to secure the antenna lead-in cable so it does not move

 

excessively in the wind to prevent fatigue failure of the cable.

 

Assembling Antenna

 

To assemble the antenna, perform the following procedure:

 

1. Unpack the antenna and become familiar with the parts and hardware.

 

2. Loosen the mounting nut and assemble the radials as shown in

 

Figure 5. Tighten jam nuts against the hub to secure the radials.

 

Retighten the mounting nut.
