WIRING CONNECTIONS
on the back of the unit. When wiring the unit, use the label to identify the wire
position with the proper function. All conductors should meet voltage and
current ratings for each terminal. Also cabling should conform to appropriate
standards of good installation, local codes and regulations. It is recommended
that power supplied to the unit (AC or DC) be protected by a fuse or circuit
breaker. Strip the wire, leaving approximately 1/4" bare wire exposed (stranded
wires should be tinned with solder). Insert the wire into the screw-clamp
terminal and tighten down the screw until the wire is clamped tightly. Each
terminal can accept up to two #14 AWG wires.
Note: The Reflective CUB4 will NOT have a screw terminal installed at the V+
