Electrical Connection
The room air conditioners are designed for
operation with 230 V AC. The electrical safety of
the device is ensured only if it is properly grounded
in compliance with current electrical safety
regulations. The local utility company’s technical
connection conditions must be observed. The
current circuit must be protected by a separate
fuse. See Technical Data for electrical protection.
The room air conditioner may only be connected or
repaired by an electrician or refrigeration technician
approved by the utility company responsible. Poorly
carried out repairs can endanger the safety of the
user.
This product complies with the valid safety
regulations for electrical devices.
Supply connection
Supply connection is to the indoor unit. The indoor
unit has a mains power connection which may have
to be extended.
Connecting the indoor and outdoor units
The indoor and outdoor units are connected by the
control line and mains cable (must be connected to
both units) provided with the device. (See also

Connecting the mains cable:
Open the plastic cover (ventilation grid) of the
indoor unit and remove the cover of the electrical
connection. Pull the mains cable from the back of
the indoor unit to the electrical connections and
connect it as shown in the circuit diagram.
At the outdoor unit, remove the side cover (KSS
2504A and 3204A) or front cover (KSS 4504C and
KSS 6004C) – the main cable is led in from the side
here too, through the rectangular opening – (using
the rectangular cable feed-through enclosed) – and
connect the mains cable according to the circuit
diagram.
Connecting the control line:
Connect the cable to the plugs in the outdoor and
indoor units.
Use the clamps provided to relieve the strain on
