BEGINNING THE WIRING PROCESS
WARNING: FAILURE TO PROPERLY GROUND THE EQUIPMENT CAN CAUSE INJURY OR DAMAGE TO THE EQUIPMENT
AND WILL VOID THE BENNETT LIMITED WARRANTY
.
WARNING: DO NOT TERMINATE THE GROUND AT THE NEUTRAL BAR OF A SUB-PANEL OR RELY ON METAL CONDUIT
FOR THIS GROUND CONNECTION. EACH SITE MASTER’S GROUNDING POST MUST BE WITHIN 1-OHM
RESISTANCE TO EARTH GROUND POTENTIAL. DO NOT USE WIRE NUTS ON GROUND CIRCUITS, USE ONLY
COMPRESSION TYPE CONNECTORS. THIS IS REQUIRED TO INITIATE BENNETT’S LIMITED WARRANTY.
CAUTION: 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.
CAUTION: Electronic power must be connected to a dedicated 15 Amp neutral breaking circuit breaker. The Site
Master is factory wired for 115/120V 50/60hz operation and must not be changed in the field. If this has
been changed in the field, the warranty is voided.
1. Remove the lower rear panel of the pedestal and locate the inlet wiring electrical conduit.
2. Remove the cover from the Power Supply by removing the lower two screws and loosening the two screws on the top backside of
the cover.
3. Place covers and screws in a location that will remind you to replace the cover once the wiring has been completed.
4. Pull the Site Master’s wires through the underground conduit and into the electronic enclosure.
5. Connect a Green Earth Ground 12-gauge (minimum), green stranded wire to the grounding lug near the Power Distribution Board.
Terminate the other end at the main electrical service panel ground bar.
Note: Use 15 Amp neutral breaking circuit breakers, which
are supplied by the customer.
6. Connect AC Power
a. Connect the neutral white 14-gauge wire to position 2 of the terminal strip.
b. Connect the hot black 14-gauge wire to position 1 of the terminal strip for electronic power. Note: 120 VAC installations L1 is
hot and L2 is Neutral.
7. Connect Data Communication Wires through ¾” conduit.
a. Connect 1 Violet 18ga. (+ positive) wire to position 3 of the terminal strip. Connect the other end to the Interconnection Box (+
positive).
b. Connect 1 White 18ga. (common) wire to position 4 of the terminal strip. Connect the other end to the Interconnection Box
(common).

INSTALLING CONDUIT AT THE SITE MASTER
WARNING: Per NFPA 70, a listed seal must be provided in each conduit run entering or leaving a Site Master. The
sealing fitting shall be the first fitting after the conduit emerges from the earth or concrete.
NOTES:

All material (fittings, conductors, U-bolts, pipe clamps, etc.) running through the hydraulics must be provided by the installer
upon installation.

Check with Federal, State, and Local Codes for conduit use in your area.

Do not use PVC conduit. Use only Rigid metal conduit.

Make sure that each Site Master has its own electrical underground conduit.

Wiring from multiple Site Masters in a single conduit is not allowed.

Make sure that vapor “seal offs” are properly installed on all conduits at and from each Site Master.

Do not put non-pump related wires, such as price signs or speakers, in the same conduit as pump wiring.

All conduit between the building and each Site Master should be a separate conduit run.
For field installations, only one
¾”
Female NPT Electrical Conduit is opening is available. Refer to the Site Master SP Footprint for
measurements.
