Electrical connection
■ The system must be well earthed.
If necessary more than once.
The earth cable(s) are to be insu-
lated.
■ When installing the units on
flat roofs, a lightning conductor
must be installed.
■ All electrical connections such
as network supply, cable remote
control etc. must be from the
main control cabinet.
■ The cables to be installed are to
be fed into the switch cabinet
through the cable conduits.
■ An electrician must determine
the sizing and selection of the
fuses and the size of cable to
be used. Note that starting the
current may be up to 10 times
nominal current.
The following electrical connec-
tions must be provided:
■ Connection to the power supply.
■ Possible enabling contact for
the unit off or stand by.
■ Possible operating mode con-
tact for cooling or heating mode
(units with HP-function).
■ Connection for cabled remote
controll (accessories).
All electrical installation work
is to be carried out only by
authorised personnel. Discon-
nect the power supply when
connecting the electrical
terminals.
! CAUTION
■ The power supply is connected
at the system; a control cable to
the interior unit is not
necessary.
■ A three phase main switch,
must be installed in the power
supply, outside of the unit.
■ Electric connections must be
installed permanently in
accordance with the
regulations.
■ Check all terminals for stability.
■ The power supply line must be
adequately insulated on-site
and the voltage drop may not
exceed permissible values.
■ Make sure that the power sup-
ply and current Is adequate for
the operation of the system and
any other equipment in use in
the area.
■ Before installation it should be
determined weather the con-
nection to the system are the
correct specifications for the
system’s rated requirements.

Cumulative ice formation in the
lower part of the finned heated
exchanger can develop under
certain weather conditions.
To prevent this ice formation,
we recommend keeping the
heat exchanger frost free on
both sides using a heating band
for example.
NOTE
Ensured discharge in the event of
leakage
Local regulations or environmen-
tal laws, for example the German
Water Resource Law (WHG), can
require suitable precautions to pro-
tect against uncontrolled draining
in case of leakage to provide for
safe disposal of escaping refrigera-
tor oil or hazardous media.
