6.9.1 MAIN AC POWER CONNECTIONS:
4. Route the power supply cable to the “AC IN” location of the control box and secure with the
appropriate strain relief for cable or conduit. See Figure 19.
5. Attach the ring terminal on the green/yellow ground wire of the power supply cable to the
grounding (earthing) stud (labeled PE) inside the control box using one of the screws
provided.
6. Strip 3/8” [10mm] of insulation from the ends of the AC power wires.
7. Connect the incoming AC power conductors to JP1 terminals L-IN (L1) and N-IN (L2). Refer
to the table below and Figure 19.
6.9.2 BLOWER CONNECTIONS:
8. Route the blower cable into the control box (see Figure 19).
9. Connect the blower’s green and yellow ground wire to a grounding (earthing) stud inside
the control box using one of the screws provided.
10. Connect the blue blower wire to terminal Blower-N on JP2 and the brown blower wire to
terminal Blower-L on JP2.
6.9.3 LIFT MOTOR CONNECTIONS:
11. Route the motor cable to the lift motor location on the controller enclosure. Pass the cable
through the cable restraint, but do not tighten the cable restraint. See Figure 19.
12. Connect the motor’s ring terminal to the ground stud.
13. Connect the conductors per wire color to terminal JP3 as shown in Figure 19. Connection
information is also shown on the exterior of the motor. Verify the connections are correct
for the line voltage (115 or 230) used.
14. Position the motor cable in the cable restraint so that there is no tension on the conductors’
connections to JP3 and tighten the cable restraint.
