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 water heater 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 water heater
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.
Line Voltage Connections
Electrical rating for the Trinity Lx is 120V
/
1 Phase
/
60 Hz
/
12A. The Trinity Lx line voltage junction box is
located in the lower right corner of the water heater cabinet on Lx200WH models and can be accessed by
removing the front door of the water heater, followed by the removal of the line voltage junction box cover. On
Lx300WH & Lx400WH models, the line voltage junction box is located at the top of the water heater cabinet on
the right hand side and can be accessed by removing the top front cover of the water heater. On Lx500WH-
Lx800WH models, the line voltage junction box is located at the back of the water heater cabinet on the power
switch side. Remove the top back cover of the water heater to access the three holes / knockouts needed for
routing field wiring into the line voltage junction box. Line voltage field connections are to be installed in
accordance with Figures and Tables 12-1(a) and 12-1(b).
Fuses (120VAC)
– The Trinity Lx is equipped with either one or two 7 Amp fuses to protect 120VAC system
components. The fast-acting fuses are located on the front of the control panel box and can be easily
accessed from the outside of the control panel.
Lx200WH-Lx400WH Control Panel:
Fuse A: Protects the blower, spark generator and PUMP B output circuits.
Fuse B: Protects PUMP A and PUMP C output circuits.
Lx500WH-Lx800WH Control Panel:
Fuse A: Protects the 120VAC circuits within the water heater.
Pump Relays (Lx500WH-Lx800WH)
– In lieu of the 120VAC pump outputs, the Lx500WH-Lx800WH
incorporates three non-powered isolation relay contacts for switching high capacity pumps. Contact
Secondary Maximum rating is 1.5HP @ 120V, 3.0HP @ 240V, or 30A. Refer to Figure 12-2(b) for Field
Wiring requirements.
Wire Protection
- When passing any wiring through the cabinet of the water heater, 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 Lx 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.
Labeling
- Label all wires prior to disconnecting them when servicing controls. Wiring
errors can cause improper and dangerous operation. Failure to follow instructions may
result in property damage or personal injury.
Continuity
- Before connecting the line voltage wiring, perform a continuity check
between all wires and ground to make sure that there are no electrical leaks that could
blow a fuse or damage electrical components. Also check the polarity of the line and
neutral wires. Line must measure 120VAC to ground; neutral must measure zero.
Failure to follow instructions may damage the unit.
Max Load
– Lx200WH-Lx400WH circulator outputs are each limited to operating a
circulator with a maximum current load of 5 Amps or a maximum 2/5 hp motor. See
Table 12-1.
