All Exhaust/Supply Fan Starters Provided in Make-Up Air Unit (MUA)

1. Wire 115 VAC power from non-shunted breaker to terminal blocks H1 (hot) and N1 (neutral) in temperature
interlock panel.
2. Wire fan switch (either provided in field, shipped loose for remote install, or provided on hood/hood utility cabinet)
to terminal blocks S1H and S1 in temperature interlock panel.
3. Wire common (C) of dedicated fire system microswitch to terminal block CP2.
4. Wire normally open (NO) of fire system microswitch mentioned in item 3 above to terminal block CP1.
5. Run three (3) low voltage wires (18 gauge) from MUA unit control center down to temperature interlock panel.
a. Terminal block R in MUA connects to terminal block CP1 in temperature interlock panel.
b. Terminal block H in MUA connects to terminal block CP2 in temperature interlock panel.
c. Terminal block G in MUA connects to the normally closed (NC) of dedicated fire system microswitch.
6. Wire the thermostats in parallel and connect between terminal blocks T1-A and T1-B (see Thermostat(s) Sensors
section for details).

Unless already done by the factory, wire all thermostats in a parallel back to terminal blocks T1-A and T1-B in
temperature interlock panel using 14 gauge 90°C minimum conductors.
Do not connect temperature sensor in series with fan
power. Depending on motor amperage, this can cause
damage to the thermostat and potentially the fan motor.
