2. Tighten the bolts to 2.4 ft-lb (3.2 Nm) using a torque screwdriver.
6.7 Connecting the RET cables
This section provides the procedure for connecting the RET cable to the RET
connector socket.
To connect RET cable:
1. Insert RET cable into keyed 8-pin RET socket on iRM4451nn00-2.
2. Twist the ferrule of the RET connector clockwise until it audibly ‘clicks’ into the
locked position.
NOTE
It is recommended that the RET connection be waterproofed using a self-fusing
tape made for that purpose. The application of the tape will vary by Installer, so
local practice will determine how the tape is applied.
