Using EC Max to replace PSC (Permanent Split Capacitor) induction motors.

• Install motor in HVAC system using a belly band mount.

 •     Select the voltage plug that matches the voltage rating of the replaced motor. 

Install the voltage plug. Connect the harness plugs to the motor. 

White Voltage Plug

115vac Systems

Yellow Voltage Plug

230vac Systems

• HIGH VOLTAGE POWER CONNECTIONS

 

 Note: The Black and White HIGH VOLTAGE POWER wires are taped together and 

flagged for identification.

  Connect the Black HIGH VOLTAGE POWER wire to a L1 line voltage power 

source that is continuously powered when the unit disconnect is closed

  Connect the White HIGH VOLTAGE POWER wire to a Neutral (115vac    

systems) or L2 (230vac systems) that is continuously powered when the 

unit disconnect is closed.

• HIGH VOLTAGE SIGNAL CONNECTION

  

Note: The Black and Red HIGH VOLTAGE SIGNAL wires are taped together and flagged 

for identification.

  Connect the Black (HV1) HIGH VOLTAGE SIGNAL wire to all of the motor 

output terminals from the HVAC board (or fan relay) including Heat, Cool 

and Continuous Fan (if applicable) that were previously connected to the 

PSC motor. Use the supplied jumper wires and terminals or wire nut all 

together.

 Insulate the Red (HV2) HIGH VOLTAGE SIGNAL wire with a wire nut.

• LOW VOLTAGE SIGNAL CONNECTIONS

 

 Note: All LOW VOLTAGE SIGNAL wires are taped together and flagged for              

identification.

  Connect the Blue LOW VOLTAGE SIGNAL wire to the thermostat common 

terminal or directly to the common side of the 24vac transformer.

  Connect the speed desired for HEAT to thermostat (W) and the speed    

desired for COOL (including A/C or Heat Pump systems) to thermostat (Y).

• NOTE: 

  After completing all connections, the technician should operate the system in 

all demand modes measuring airflow using industry best practices. To adjust 

the airflow, change the speed selection connected to the appropriate thermostat 

terminal. 

  If the system has a Continuous Fan selection at the thermostat, this demand 

will energize the motor through the fan relays to energize the Black (HV1) HIGH 

VOLTAGE SIGNAL input which will operate the motor at the default continuous fan 

speed. This speed is approximately 200 rpm slower than the LOW speed from the 

LOW VOLTAGE SIGNAL CONNECTIONS. If a higher continuous fan speed is desired, 

connect any unused speed selection to thermostat terminal (G).
