1 Safety Precautions
• For all electrical work,
follow all local and
national wiring standards,
regulations, and the
Installation Manual.
Connect cables tightly,
and clamp them securely
to prevent external
forces from damaging
the terminal. Improper
electrical connections
can overheat and cause
fire, and may also cause
shock. All electrical
connections must be
made according to the
Electrical connection
diagram located on the
panels of the indoor and
outdoor units.
• All wiring must be
properly arranged to
ensure that the control
board cover can close
properly. If the control
board cover is not closed
properly, it can lead to
corrosion and cause the
connection points on the
terminal to heat up, catch
8 / EN
fire, or cause electrical
shock.
• If connecting power to
fixed wiring, an all-pole
disconnection device
which has at least 3mm
clearances in all poles,
and have a leakage
current that may exceed
10mA, the residual
current device (RCD)
having a rated residual
operating current not
exceeding 30mA, and
disconnection must be
incorporated in the fixed
wiring in accordance with
the wiring rules.
Take note of fuse
specifications
The air conditioner's circuit
board (PCB) is designed
with a fuse to provide
overcurrent protection. The
specifications of the fuse
are printed on the circuit
board, such as:
T20A/250VAC (for
<24000Btu/h unit),
T30A/250VAC (for
