POWER CABLE

TM 11-5820-917-13

WARNING

A three-wire (line, neutral, and safety ground) AC line power connection

is required when operating the equipment. If a 3-wire safety grounded

AC power receptacle is not available, a separate ground wire must be

installed from the chassis ground to an earth ground. Without an adequate

ground, the equipment chassis and frame will float to a dangerously high

potential.

NOTE

Before connecting AC power to unit, be sure the correct fuse is installed

(4A for 115V, and 2.OA for 230V), and toggle switch (as marked on 4028

chassis) is in correct position.

2-16. POWER CABLE. The receiver is provided with a detachable line cord (10 feet

long) having a standard EIA 5-15P, 15-ampere plug (2 blades with round grounding

pin) at the supply end. Exposed portions of the equipment are grounded through

the round pin of the plug for safety. A non-grounding two blade receptacle should

not be used without use of a grounding type connector adaptor.

CABLES

AND

CONNECTORS

2-18. A list of cables used with the receiver are given in table 2-1. Connectors used

are given in table 2-2. All connections are made at the rear of both units and are

illustrated in figure 2-5.

2-19. Antenna connections to the RCS-4B (to either the 6043 power divider or

directly to the 4028 inputs) are type N coaxial connectors requiring a mating antenna

cable plug (type N) such as UG-21, UG-1185, or UG-536.

2-20. DATA I/O CONNECTOR. The remote data output connector J7 on the 6025

rear panel is a 12-pin circular connector (Amphenol 348-40E10-12S1) which mates with

an Amphenol 348-46E10-12P1 cable plug or a MIL-C-81511 plug part number M81511/

06EB01P1. Signals available on J7 allow data collection and processing of RCS-4B

sounder data by external equipment such as the BR Frequency Management Terminals

(FMT series) . For further information on the use of the remote data outputs contact

BR communications. The pin out connections of J7 are listed in table 2-3.

2-21. BATTERY INSTALLATION

2-22. Two different types of standby battery supplies are used in the RCS-4B .

Some receivers have a non-rechargeable battery supply (P/N 6025- 1008) that uses

standard D-cell batteries. Other receivers have a rechargeable supply (P/N 6025-

1018) that includes an integral charging circuit and uses sealed lead acid cells.

Refer to either paragraph 2-23 or 2-24 as applicable.
