Wiring connection
NOTE: Before performing any electrical work, turn
off the main power to the system.
CAUTIONS
• Do not touch the capacitor even if you have
disconnected the power for there is still high
voltage power on it, or electric shock hazard may
occur. For your safety, you should start repairing at
least 5 minutes later after the power is
disconnected.
• The power is supplied from the Outdoor Unit. The
Indoor Units are connected with signal wires or
power cords are connected reliably and correctly,
or the air conditioner could not run normally.
NOTE:
The cable size and the current of the fuse or switch
are determined by the maximum current indicated on
the name plate which located on the side panel of the
unit. Please refer to the nameplate before selecting
the cable, fuse and switch. Please refering to the
above tables and choosing the proper wire size under
the local electrical requirements.
Connect the cable to the outdoor unit
1. Remove the electrical control board cover from the
outdoor unit by loosening the screw as shown in
Fig.61
2. Connect the connective cables to the terminals as
identified with their respective matched
numbers on the terminal block of indoor and
outdoor units.
3. Secure the cable on to the control board with the
cord clamp.
4. To prevent the ingress of water, from a loop of the
connective cable as illustrated in the installation
diagram of indoor and outdoor units.
5. Insulate unused cords(conductors)with PVC-tape.
Process them so they do not touch any electrical or
metal parts.
CAUTIONS
Make sure to connect the indoor unit (A,B, C, D, E) to
the Hi and Lo valve and terminals of signal wires(A, B,
C, D, E) of outdoor unit as identified with their
respective matched connection. Wrong wiring
connections may cause some electrical parts to
malfunction.
