STEP 7
- Connect Belimo actuator, LF24-SR (item 1) with label 'RA' , which is now located at the assembly damper on the
indoor base panel to terminal block with label 'RA' inside the junction box.
- There are four wires on the actuator with different colours (black, red, green and white colours). Connect the
wires as below:
Black colour wire - connect to first pole of
terminal block with label 'GND' .
Red colour wire - connect to second pole of
terminal block with label
'+24V' .
Green colour wire - connect to third pole of
terminal block with label 'DCV' .
White colour wire - connect to fourth pole of
terminal block with label 'FB' .
(You may refer to sticker wiring diagram which is
located on the front cover of junction box.)
Wrong wiring connection may cause the malfunction on actuator or economizer controller board or both. Tie the wires
with releasable cable ties under the junction box.
- Then, connect Belimo actuator, LF24-SR (item 1) with label 'OA' , which is now located at the assembly damper
on the side panel to terminal block with label 'OA' inside the same junction box. Follow the same method used
for wiring connection between actuator 'RA' and terminal block 'RA' . Next, attach the side panel to the unit. You
may need to do proper arrangement on the actuator wires by using cable ties (field supply) before attach the
side panel to the unit.
