12. Wiring the RSCB
Once the control valves, pulser, and ETVC kit (if so equipped) have been mechanically
installed, they need to be wired to the RSCB. The RSCB has seven ½” NPT ports to
accommodate the wires and cables that enter it. Typically, the ports in the back are
used for the signal cables that run to the truck cab and for the optional three-way
solenoid. The installer must choose the ports that best fit the requirements of a particular
installation.
q
Remove the 12 bolts that secure the cover of the RSCB.
q
Gently lift the cover off of the RSCB until the black coiled wire is accessible.
q
Remove the telephone style connector from socket J8 on the RSCB terminal board.
q
Place the top cover assembly out of the way.
The wires from the valve, ETVC kit, and pulser need to be routed through suitable
conduit to the RSCB.
The type of conduit used depends on the physical constraints of the installation and the
safety rating required.
Thin wall conduit, Liquid-Tight, and Synflex are among the choices.
The conduit hubs on the RSCB, solenoids, and pulser are all ½ "-14 NPT.
The conduit/cable entrances must be sealed inside and out using appropriate cable
glands to prevent moisture from accumulating in the RSCB.
Avoid chaffing or nicking the cables when pulling them through conduit or compression
fittings.
When routing the conduit, allow ample clearance for service access to the meter and
strainer.
If the system is installed inside a meter box, make sure that there is enough clearance to
close the door.
The RSCB terminal board has six removable terminal blocks (J1-J6) for ease of field
wiring.
Once the wires have been routed into the RSCB, they should be connected to the
appropriate terminal block.
When routing wires to respective terminal block, cut wire to length (always leave 1”-2”
extra length).
When attaching wires to the terminal blocks, remove the terminal block by pulling it
straight up from the circuit board.
q
Use a 1/8-inch screwdriver to back off the screw at the desired terminal block
location.
q
Strip 7/32” inch of the insulation from the end of the wire and insert the wire into the
desired location on the terminal block.
q
Retighten the screw and check to make sure that the wire is fully inserted and that
none of the strands are loose.
q
Insert the terminal block onto corresponding mating connector on the RSCB terminal
board.
