WIRING INSTRUCTIONS
GENERAL WIRING INSTRUCTIONS
WARNING: THESE NOTES ARE “MUST DO” REQUIREMENTS TO ENSURE A SUCCESSFUL INSTALLATION THAT MEETS BENNETT’S
LIMITED WARRANTY REQUIREMENTS.
1. Electrical wiring and equipment must be in accordance with Article 500 of NFPA Code 70 and Class 1, Division 2, Group B (hydrogen),
NFPA Code 2 Hydrogen Technologies Code, state, and local electrical codes.
2. Check with Federal, State, and Local Codes for conduit use in your area. Bennett recommends rigid metal conduit.
3. Do not use PVC conduit. Use only Rigid metal conduit.
4. All wiring gauges is minimum required, stranded wire with THHN insulation must be used. Do NOT use wire smaller than listed on the
Bennett wiring diagrams. For long runs increase wire size accordingly.
5. Do not reuse old wire from an existing installation.
6. Do not use wire nuts on data communication wires. Do not splice data communication wires they must be direct runs.
7. Do not use wire nuts on ground circuits, use only compression type connectors.
8. 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 819 Power Board. The wire separator is needed to properly seal the conduit in the last step of installation.
9. Electronic power must be on a dedicated circuit breaker. The dispenser is factory wired to accept AC voltages ranging from 100 to 250
volts AC for its operation.
10. Electronic power for all dispensers at the installation must be wired to the same AC line phase or damage will result to the dispensers.
This will avoid a cross phase condition on the remote relay control wires.
11. Use 15 AMP neutral breaking circuit breakers, which are supplied by the customer. The maximum distance from the breaker panel to
the dispenser is 500 feet (150m).
