8 Electrical wiring
8.1 General information
A protected power supply cable is to be connected
to the outdoor unit and 4-core control line is to be
connected to the indoor unit respectively.
DANGER!
All electrical installation work is to be per-
formed by specialist companies. Disconnect
the power supply when connecting the elec-
trical 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.
n We recommend installing a main / repair switch
on the building close to the unit. This is the
responsibility of the customer.
n The terminal blocks for making the connections
are located at the rear 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 in con-
junction with the unit, it may be necessary to
install an additional relay with a higher contact
rating after the switch-off contact on the pump
to switch off the compressor.
The control line to the outdoor unit contains a data
cable which serves to realise communication
between the indoor unit and the outdoor unit. This
is used for controlling the cooling and heating
capacity and for forwarding malfunction codes to
the indoor unit. If the length is insufficient, you can
extend the control lines on the indoor unit.
Make the connection as follows:
1. Open the air inlet grill.
2. Remove the covers on the right-hand side
(Fig. 30).
3. Connect the customer-laid control line to the
terminals (Fig. 30).
4. Join the customer-laid control line to the sup-
plied control line in a professional manner.
5. Insert the control line plug into the corre-
sponding socket on the outdoor unit.
6. Re-assemble the unit.
