Wiring Notes: These notes are must do requirements to ensure a successful installation that
meets Bennett's limited warranty requirements.
1. Check with Federal, State and Local Codes for conduit use in your area. Bennett recommends rigid
metal conduit.
2. Use only stranded wire with listed gas and oil resistant insulation. Do not use wire smaller than
listed on the Bennett wiring diagrams. For long runs increase wire size accordingly.
3. DO NOT USE WIRE NUTS ON DATA LINES. DO NOT SPLICE DATA WIRES THEY MUST BE
DIRECT RUNS.
4. When the dispenser wires are pulled though the underground conduit leave at least 72" higher than
the base of the dispenser to allow enough length to reach the dispenser terminal strip.
5. The wire separator (supplied with the pump) must be installed on the wires as they exit the pump
conduit before the wires are terminated to the power board. The wire separator is needed to
properly seal the conduit in the last step of installation.
6. Electronic power must be on a separate dedicated circuit breaker. Do not put submerged pump or
self-contained pump power on this circuit breaker. Up to two dispenser may be placed on (1) 15
amp circuit breaker.
7. WARNING: DO NOT CROSS PHASE THE DISPENSERS OR DAMAGE WILL OCCUR. When
installing more than one dispenser the remote sub-pump relay control wires must be on the same
phase or cross phasing will occur at the sub-pump relay. This means that the electronic power for
all dispensers at the site must be on the same phase.
8. Bennett requires the installation of RC networks across the coil and contact of the sub-pump relays
for proper operation of the dispenser. Failure to install the RC networks will void Bennett's limited
warranty.
9. The power for the motors in self-contained pumps must be located on the opposite phase from the
dispenser electronic power or be connected at 230V. This is necessary to limit the electronic noise
from feeding back into the dispenser's electronic power. Failure to observe this will create problems
with the operation of the dispenser's computers. Note: if 230v motor power is used be sure to set
the motors to the high voltage setting by moving the switch on the motor next to the pulley to the
high position.
10. The maximum distance from the breaker panel to the dispenser is 500 feet. For self-contained
units, increase the motor wire size from 14Ga to 12Ga for runs over 50ft. and to 10Ga. for runs over
100ft.
Beginning the Wiring Process
Open the pump and locate the inlet wiring electrical conduit.
distribution board by removing the lower two screws and loosening the two screws on the top back side
of the cover. Place cover and screws in a location that will remind you to replace the cover once the
wiring has been completed. Pull the dispenser wires through the underground conduit and into the
electronic enclosure.
Installing the Wire Separator
A safe installation requires that a wire separator be installed
on the wires as you rout then through the conduit and into
the dispenser's electronic enclosure. The wire separator
holds the wires apart to ensure that the seal off compound
fully seals around each wire . You will apply the seal off
compound during the last step of installation.
prevent gasoline fumes from working their way into the
electronic enclosure. The wire separator is supplied in the
plastic bag located inside the electronic enclosure attached
to the side wall.
