The indicated cross-sections are suitable for a wiring
length of up to 5 metres.
ATTENTION ELECTRIC DANGER
Before making electrical connections, turn off
the main switch of the system.
WARNING
WRITE DOWN THE SPECIFICATIONS OF THE
FUSES.
The air conditioner board (PCB) is equipped
with a fuse for overcurrent protection. Fuse
specifications are printed on the circuit board,
for example:
Indoor unit: T5A/250VAC - T10A/250 VAC
NOTE: The fuse is ceramic.
1 Prepare the cable for connection:
– Using a wire stripper, strip the rubber sheath at
both ends of the cable and expose approximately
15 cm of the internal conductors.
– Strip the insulation sheath at the ends of the
conductors.
– Using a crimping tool, crimp U-type wire terminals
to the ends of the conductors.
CAUTION
When crimping, clearly identify live cables ("L")
and other cables.
2 Take the cover off the indoor unit's electrical panel.
3 Take the cover off the indoor unit's electrical panel
with a screwdriver. This will give you access to the
terminal block.

WARNING
All connections must be made exactly as
shown in the wiring diagram on the inside of
the terminal block cover of the indoor unit.
4 Pass the power cable and the signal cable through
the cable outlet.
5 Connect the U-shaped wire terminal to the terminals.
Match the colours/labels of the cables to the labels
on the terminal block, then screw the U-shaped wire
2
terminal of each cable firmly to the corresponding
terminal block. Refer to the serial number and wiring

6 Looking at the front side of the unit, match the colours
of the cables to the labels on the terminal block,
connect the U-shaped terminals and screw each
cable securely to the corresponding terminal.
CAUTION DANGER
– DO NOT SWITCH LIVE AND NEUTRAL
CABLES. Such a configuration is dangerous
and may cause the air conditioner to
malfunction.
– The refrigerant circuit can get very hot. Keep
the interconnection cable away from the
copper pipe.
7 Secure the cables with the corresponding cable ties.
The cable must not be slack and must not pull the
U-shaped wire terminal.
8 Refit the cover on the electrical panel.
