Relay Board Installation
Opening the Indicator Housing
• Unfasten the 4 side screws of the Indicator housing, pull the front housing
section forward.
WARNING: ELECTRICAL SHOCK HAZARD EXISTS WITHIN THE HOUSING. THE
HOUSING SHOULD ONLY BE OPENED BY AUTHORIZED AND QUALIFIED
PERSONNEL. REMOVE ALL POWER CONNECTIONS TO THE UNIT BEFORE
OPENING. IF THE UNIT CONTAINS AN OPTIONAL RELAY CONTROL BOARD,
ADDITIONAL AC OR DC POWER CONNECTIONS MAY EXIST WITHIN THE HOUSING.
• Mount the PC board to the rear plate as shown in Figure 1 using 4
of the small screws supplied.

Cable Installation

• Connect the long cable supplied with the kit to connector J10 on the main PC
board. Connect the other end of the cable to either connector at the top of the
Relay Board. (See Figure 1). Using the cable tie supplied, attach the cable
to the plastic mount at the bottom of the housing. (Other cables may already
be attached to this same mount.) If the optional RS422/485 board has been
previously installed, do not use the long cable, instead use the short cable
supplied in the kit to connect the Relay Board to the similar connector on the
RS485 board.
