Important Wiring Considerations
Please read carefully and apply the following information when
wiring the
MODGAS-X Controller. The MODGAS-X Controller
requires the following electrical connections:
1. 18 gauge minimum wire unless otherwise noted.
2. 24 VAC power connection with an appropriate VA rating.
3. Supply Air Temperature Sensor and Heat Enable must have
24 gauge minimum wire.
4. All 24 VAC wiring must be connected so that all ground
wires remain common. Failure to follow this procedure can
result in damage to the module and connected devices.
5. All wiring is to be in accordance with local and
national electrical codes and specifi cations.
6. Check all wiring leads at the terminal block for tightness.
Be sure that wire strands do not stick out and touch
adjacent terminals. Confi rm that all transducers required for
your system are mounted in the appropriate location and
wired into the correct terminals.
WARNING: Do Not Connect Power To VOUT/Ground
Terminal Block!
WARNING: Observe polarity! All boards must be wired
GND-to-GND and 24 VAC-to-VAC. Failure
to observe polarity could result in damage to
the board.
