EASi 4.5m Antenna Installation Kit

EASi 4.5 Meter Antenna Installation Kit

1 Introduction

This document describes an installation kit that is used in conjunction with the RC2K90INT-2E interface

box which allows an RC2000 antenna controller to operate an EASi 4.5m meter antenna. Efficient Antenna

Systems inc. (EASi) may be contacted at WWW.EASiSat.COM . The EASi antenna uses 1 ½ HP 90 VDC

motors, so the larger version of the interface box is used. The heater option is normally included in this

version. The following issues are addressed in this paper:

• The AC power requirements of the interface box.

• Recommended types of cable that may be used to connect the RC2000 antenna controller to the

interface box.

• A controller - interface box - antenna wiring diagram.

• RC2000EASi software configuration parameters.

• A conduit/wiring schedule.

• A Bill of Materials.

2 AC Power

The interface box is housed in a NEMA 4 weatherproof enclosure. In the Standard configuration, 120 Volt

AC power must be provided at the antenna pad. All ungrounded AC line supply conductors must be fused

or protected with circuit breakers, do not fuse neutral or grounded conductors. A 25 or 30 amp circuit

breaker is sufficient. In addition, an AC emergency disconnect conforming to the NEC (National Electric

Code) and other applicable electrical codes must be provided at the antenna and be readily accessible to

personnel in the vicinity of the antenna.

The AC line input of the interface box will be pre-wired with 10 feet of 12/3 cable. The interface box has a

straight 1/2” conduit fitting appropriate for flexible steel reinforced liquid tight conduit of which 8 feet is

supplied. The user should make provisions to accept this type of conduit on the electrical box which houses

the emergency disconnect. Alternatively, the user can replace the liquid tight conduit fitting with a different

type of conduit fitting. The interface box is punched with a 7/8” diameter hole for the liquid tight conduit

fitting.

3 Antenna Controller to Interface Box Interconnect Cable

The user must supply the cable to connect the RC2000 to the interface box. On the interface box there is a

CN-GY-RB-3704 RACO 1 inch cable compression fitting reserved for mechanically connecting the

interconnect cable to the interface box. The conduit fitting has a 0.85” to 1.00” diameter opening which the

interconnect cable must pass through to enter the interface. Make sure that the interconnect cable(s)

selected will fit through the opening. Alternatively, the user can replace the liquid tight cable fitting with a

different type of conduit fitting. The interface box is punched with a 1.37” diameter hole for the cable

fitting. This hole is appropriate for 1 inch conduit.

The cable must have 2 pairs of 20 AWG (or heavier) conductors to carry the motor control signals (forward

- stop - reverse). Shielded conductors are not necessary for these signals but if shielded conductors are

available the shield can be used. For shielded motor control conductors, follow the rules given below for

the shielded sensor cables. In addition to the motor control signals a pair of individually shielded triples

with drain wires are necessary for the sensor connections.
