Electrical installation
General
ACVM 270 must be installed via a circuit breaker with a
minimum breaking gap of 3mm.
Other electrical equipment, except the outdoor sensors,
current sensors and outdoor module AMS 10 is already
connected at the factory.
Disconnect the indoor module ACVM 270 and outdoor
module AMS 10 before insulation testing the house
wiring.
For fuse ratings, see technical data, “Fuse protection”.
If the building is equipped with an earth-fault breaker,
ACVM 270 should be equipped with a separate one.
Connection must not be carried out without the permis-
sion of the electricity supplier and under the supervision
of a qualified electrician.
5x2.5 mm

cable must be used for the connection
between ACVM 270 and AMS 10.
Cables must be routed so that they are not damaged by
metal edges or trapped by panels.

This means that phase L3 is loaded with up to 15 A dur-
ing compressor operation.

Electrical installation and service must be carried out
under the supervision of a qualified electrician. Elec-
trical installation and wiring must be carried out in
accordance with the stipulations in force.
