Instructions for Earth Grounding the Equipment
WARNING:
Failure to properly ground the equipment can cause injury or damage to the
equipment and will void the Bennett limited warranty.
This product must be properly grounded. Each dispenser requires a 12-gauge earth ground wire.
Grounding provides a path of least resistance for electric current to reduce the risk of electric shock.
Grounding is also required to protect the dispenser's computer from external electrical noise generating
devices. The ground wire connection must provide 1 ohm (or less) resistance to earth ground. To
establish a good earth ground, follow this procedure:
1. Connect a 12-gauge (minimum), green stranded wire to the grounding terminal near the terminal
block in the electronic head and to the ground on the power supply ground terminal number 1.
2. Pull the wire through the rigid metal conduit and connect it directly to the ground bar of the MAIN
electrical service panel, not a sub-panel. Do NOT rely on the metal conduit as a ground.
DO NOT USE WIRE NUTS ON GROUND WIRES. USE COMPRESSION CONNECTORS ONLY.
3. Do not daisy-chain ground wires. All ground circuits must be dedicated wires connected directly to
the ground bar in the main electrical panel. A direct connection to the site's ground rod must be
connected to the ground bar in the main electrical panel.
4. Ensure that a 14-guage minimum ground wire is connected between the dispenser ground lug and
the power board terminal 1. This wire must be connected for proper operation to occur.
AC POWER INSTALLATION
Each remote dispenser uses one 115V, 50/60 Hz or 230V, 50/60 Hz circuit for dispenser power. Make
sure the power source has the correct frequency and voltage. Connect the electrical circuit to the
terminal strip on the power supply board.
All references to 115VAC in this manual can also be identified as 230VAC if the dispenser ordered is for
230 VAC. Note: 115VAC installations: L1 is hot and L2 is Neutral. In 230VAC installations: L1 is hot
and L2 is the other phase hot.
Electronic Power Connections:
1. Connect the White 14ga. wire in 115V circuits or the Red 14ga. wire in 230V circuits to the power
board terminal 2.
2. Connect the Black 14ga. wire to the power board terminal 3.
3. Electronic power must be connected to a dedicated 15 amp. circuit breaker. The dispenser is
factory wired for 115V or 230V operation and may not be changed in the field. (If this is done, the
warranty is voided.) Electronic power for all dispensers at an installation must be wired to the same
AC line phase or damage from cross phasing will result in the remote sub-pump relay control
circuits.
Rules to ensure proper operation:
1. Each remote dispenser uses one 115V, 50/60 Hz or 230V, 50/60 Hz circuit for dispenser power. Put
no more than two (2) Horizon dispensers on a circuit breaker (for Electronic Power).
2. Do not connect any other devices or motors to these circuits.
3. Put the pump wiring in a separate conduit. Do not put non-pump related wires, such as price signs
or intercoms, in the same conduit as pump wiring.
4. Use only 14-gauge stranded gas and oil resistant THHN wire.
5. Do not use wire nuts within the dispenser or the wire run from the breaker panel to the dispenser.
WARNING: All Dispenser AC Power circuits (for Remotes only) must be on the same phase or
damage will result to the dispenser power board or the sub-pump relay box.
