Electrical wiring
8.1 General Information
A protected power supply cable is to be connected
to the outdoor unit and a five-core control line to
the indoor unit respectively.
DANGER!
All electrical installation work is to be performed
by specialist companies. Disconnect the power
supply when connecting the electrical terminals.
WARNING!
All electric lines are in accordance VDE regula-
tions to dimension and to lay.
NOTICE!
The electrical connection of the units must be
carried out in accordance with VDE regulations.
We recommend using an FI circuit breaker that
is sensitive to all currents, as increased leakage
currents can occur.
We recommend using shielded wires for the
control lines.
Check all plugged and clamped terminals to
verify that they are seated correctly and make
permanent contact. Tighten as required.
8.2 Connecting the indoor unit
n
We recommend that a mains/repair switch be
installed near the outdoor unit.
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 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.
The control line to the outdoor unit contains a data
cable which is used to establish communication
between the indoor unit and the outdoor unit. This
is used for controlling the cooling and heating
capacity and for forwarding alarm 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 panel of the unit.
2.
Remove the covers on the right-hand side
3.
Feed the control line through the opening on
the rear of the unit in the connection area.
4.
Connect the control line to the terminals
5.
Re-assemble the unit.
