Electrical Connections
Make wiring connections to the unit as indicated on enclosed wiring diagram. This modular blower shall be connected into a permanently live
electric circuit. It is recommended that modular blower be provided with a separate "circuit protection device" electric circuit. The modular
blower must be electrically grounded in accordance with local codes or in the absence of local codes with the National Electrical Code, ANSI/NFPA
70, if an external electrical source is utilized. The integrated modular blower control is polarity sensitive. The hot leg of the 120V power
supply must be connected to the black power lead as indicated on the wiring diagram.
Refer to the Wiring Diagram section in this document and unit wiring diagram attached to modular blower.

NOTES:
1) HP = Wiring used for Heat Pump systems
2) Remove Y1 - O jumper on IFC for HP systems.
3) Y1 and/or Y2 must connect from the thermostat to the
IFC for proper airflow.
4) For PWM (BK) enabled thermostats, cut the BK jumper
on the IFC and connect wiring.
