Field Wiring

12.0 FIELD WIRING
All wiring must be in accordance with the Canadian Electrical code, CSA C22.2 and any applicable local codes.
Ensure that the wiring complies with this manual. The boiler must be electrically grounded in accordance with
the National Electrical Code ANSI/NFPA 70, local codes, and/or the Canadian Electrical Code CSA C22.1.
Avoid Shocks - To Avoid Electrical Shock, turn off electrical power to the boiler prior to
opening any electrical box within the unit. Ensure the power remains off while any
wiring connections are being made. Failure to follow these instructions may result in component failure, serious
injury or death.
Field Wiring - Wire grommets must be used to secure wiring and prevent chafing when
passing wiring through the cabinet wall. Failure to follow instructions may damage unit.

Wiring Connections

Electrical rating for the Trinity Tx is 120V / 1 Phase / 60 Hz / 12A. All wiring connections to the Trinity Tx are
made at the junction box, located behind the control panel at the bottom of the boiler cabinet, see Figure 12-1.
Field wiring enters the cabinet through holes located on the bottom (underside) of the boiler cabinet; use suitable
strain-relief grommets to protect the wires. Field wiring connections are to be installed in accordance with
instructions provided in Figure 12-2 and Table 12-1.
Fuse (120VAC) - The Trinity Tx is equipped with a 3.15 Amp fuse located at "F1" on the boiler controller at the
top left; the fuse protects all 120VAC circuits within the boiler, as well as any circulators connected to it. A
spare fuse is located directly below the operating fuse in an open holder.

Wire Protection - When passing any wiring through the cabinet of the boiler, the
installer must use wire grommets suitable for securing the wiring and preventing chafing.
Failure to follow instructions may result in component failure, serious injury or death.
Power Supply - The Trinity Tx is designed to be powered using a single phase 120VAC
power supply that is fused (or protected via a circuit breaker) to allow a maximum of 15
Amps. Failure to follow instructions may result in component failure, serious injury or death.
