Field Wiring - NTI Matrix Installation And Operation Instructions Manual

Matrix

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.
Line Voltage Connections
The Matrix line voltage junction box is located on the right-hand side of the boiler cabinet. Each unit is
provided with three knockouts for routing field wiring into the line voltage junction box. Line voltage field
connections are to be installed in accordance with Figure 12-1 and Table 12-1.
Fuse (120 VAC) – The Matrix Sentry controller is equipped with one 15 Amp fuse to protect the 120VAC pump
output. The fuse is located under the cover of the Sentry 2100 control (red control).
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 Matrix is designed to be powered using a single phase 120 VAC
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 120 VAC to ground; neutral must measure zero.
Failure to follow instructions may damage the unit.
