SYSTEM WIRING
Before connecting the field wiring, check the wiring for opens, shorts, grounds and stray
voltages.
WARNING
Damage may result if a high voltage insulation tester is used on wiring while connected to the control unit.
Terminate the field wiring to the main board in accordance with the diagrams in System Wiring
Section and the system design documents.
All wiring must be in accordance with local codes and the National Electrical Code. Use only
wire as described in Article 760 of the National Electric Code.
AC Supply Connection
Wire the AC supply to terminal block TB1 on the main board. The supply should originate from
a separate, fused circuit. It should be provided with a breaker or other means of isolation.
(Refer to Primary and Secondary Wiring Section for connection diagram.)
Observe the wiring order — the bottom terminal is ground and must be wired back to the
electrical panel ground (earth) bonding point or another good ground acceptable to the
authority having jurisdiction and the electrical inspector. The neutral wire must be taken back
to the electrical panel neutral distribution bar and must not be grounded.
Dangerous voltages will be present on this terminal block and on other components
surrounding it and the transformer when the AC supply is turned on. Do not touch.
