Electrical wiring
8.1 General connection
and safety instructions
A protected power supply cable is to be connected
to the outdoor unit and a four-core control line with
a minimum cross-section of 1.5mm
2
. To avoid EMC
interference, only use shielded cable for this pur-
pose and connect the shielding on both sides.
DANGER!
All electrical installation work is to be performed
by specialist companies. Disconnect the power
supply when connecting the electrical terminals.
NOTICE!
The electrical connection for the units must be
made at a separate feedpoint with a residual
current device in accordance with local regula-
tions and should be laid out by an electrician.
We recommend using shielded wires for the
control lines.
n
We recommend that a mains/repair switch be
installed near the outdoor unit.
n
The terminal blocks for establishing the con-
nections are located on the side of the unit.
When the unit is installed, measurements can
be made from the front by removing the cover.
n
If an optional condensate pump is used as an
accessory in conjunction with the unit, it may
be necessary to install an additional relay with
a higher contact rating after the switch-off con-
tact on the pump to switch off the compressor.
n
The control lines used should comprise
shielded wire, if laid in areas exposed to strong
magnetic fields.
n
Details concerning the electrical protection of
the system are provided in the technical data.
8.2 Connecting the indoor unit
Make the connection as follows:
1.
Open the air inlet grill.
2.
Loosen the switch cabinet's cover (Fig. 46).
3.
Feed the voltage-free cable through the edge
protection rings on the control box and clamp
the cable in the strain relief.
4.
Then connect the cable in accordance with
the wiring diagram (see chapter “Electrical
wiring diagram”).
5.
Connect the electrical plugs on the cover to
the mating connectors on the cassette. It is
not possible to incorrectly connect these.
6.
Re-install all disassembled parts.
