Running Conduit/Wiring for WPLLD System
WPLLD Controller Module
PUMP POWER WIRING
1. Turn Off, tag, and lockout all AC power to the console, dispensers and submersible pumps.
2. Run conduit from the Power Bay of the console to the main power panel.
3. For each line to be monitored, pull two #14 AWG wires (one black and one white wire are recommended) between
the 15 A circuit breaker on the main power panel and the Power bay of the console. Or you may pull two #14 AWG
wires (one black and one white) from the 15 A circuit breaker on the main power panel to the Power bay of the
console, and jumper to these wires using approved wire nuts for each WPLLD Controller Module.
PUMP CONTROL WIRING
1. Run conduit from the Power Bay of the console to the submersible pump relay control box. The conduit must be
large enough to fit
two #14
AWG wires for each pump control leg you are installing.
IMPORTANT! There are knockouts for ¾-inch, 1-inch or 1¼-inch conduit in the console. When deciding on the size
and number of conduits required, consider the number of wires entering the console and code requirements.
2. Pull two #14 AWG color-coded or marked wires for each Wireless PLLD Module between the Power bay of the
console and the submersible pump relay control box.
IMPORTANT! Since wiring for multiple pump controls may be entering the console through the same conduit open-
ing, be sure to color code or mark each wire to identify its source!
WPLLD AC Interface Module
1. Turn Off, tag, and lockout all AC power to the console, dispensers and submersible pumps.
2. Run conduit from the Power bay of the console to the 240 Vac source supplying the STPs. Verify submersible pumps
are using the same phase of 240 Vac power. If necessary, rewire them to the same phase.
3. Connect two non-isolated (i.e. not separated from main power by a transformer or other device) 240 Vac lines to the
“L1” and “L2” terminals on the “AC” plug on the Wireless PLLD AC Interface Module in the Power bay of the
console as shown in Figure 3-1. Note that the unlabeled terminal on the far right is not used. (Affix the warning label
provided in the Installation Kit onto the circuit breaker panel to indicate that WPLLD is using this circuit.)
WARNING
TURN OFF, TAG, AND LOCKOUT POWER TO THE CONSOLE AND SUBMERSIBLE
PUMPS WHILE INSTALLING THE WPLLD SYSTEM.
Use only supplied service parts to avoid compromising safety.
Do not allow WPLLD pump control wires to share conduit with wires from intrinsically safe de-
vices such as probes and sensors.
Ensure that any assembled conduit only enters the console through the properly designated
knockouts.
Wiring must comply with all applicable requirements of the National Electrical Code; federal,
state, and local codes; and any other safety codes.
