General
AMS 10 and HBS 05 does not include an omnipolar circuit
breaker on the incoming power supply. Therefore, its
supply cables must each be connected to their own cir-
cuit breaker with a breaking gap of at least 3 mm. Incom-
ing supply must be 230V ~50Hz via electrical distribution
board with fuses.
■
Disconnect the SPLIT box HBS 05 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,
AMS 10 should be equipped with a separate one.
■
Connection must not be carried out without the per-
mission of the electricity supplier and under the super-
vision of a qualified electrician.
■
Cables must be routed so that they are not damaged
by metal edges or trapped by panels.
■
AMS 10 is equipped with a single phase compressor.
This means that one of the phases will be loaded with
a number of amperes (A) during compressor operation.
Check the maximum load in the table below.
Maximum current (A)Outdoor module
15AMS 10-6
16AMS 10-8
23AMS 10-12
25AMS 10-16
■
Maximum permitted phase loading can be restricted
to a lower maximum current in the indoor module or
control nodule.
NOTE
Electrical installation and any servicing must
be carried out under the supervision of a qual-
ified electrician. Disconnect the current with
the circuit breaker before carrying out any ser-
vicing. Electrical installation and wiring must
be carried out in accordance with the national
stipulations in force.
NOTE
Check the connections, main voltage and phase
voltage before the machine is started, to pre-
vent damage to the air/water heat pump
electronics.
NOTE
The live external control must be taken into
consideration when connecting.
NOTE
If the supply cable is damaged, only NIBE, its
service representative or similar authorised
person may replace it to prevent any danger
and damage.
