General
All internal electrical equipment is connected at the
factory. External connections have to be connected ac-
cording to the applicable unit specification.
■
Disconnect the air treatment unit before insulation
testing the house wiring.
■
If the building is equipped with an earth-fault breaker,
GreenMaster-HP should be equipped with a separate
one.
■
If a miniature circuit breaker is used, this has to have
at least motor characteristic “C”. See the enclosed unit
specification for fuse size.
■
Communication and sensor cables to external connec-
tions must not be laid close to high current cables.
■
The minimum area of communication and sensor
cables to external connections must be 0.5 mm² up to
50 m, for example EKKX or LiYY or equivalent.
■
When routing a cable in GreenMaster-HP, cable
grommets must be used. Secure the cables in the
grooves in the bottom section of the distribution box.
NOTE
The switch (SF1) must not be set to " " or "
"
until the heating medium circuit has been
filled. Components in the product could be
damaged.
NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician. Cut the current with the circuit
breaker before carrying out any servicing.
Electrical installation and wiring must be car-
ried out in accordance with the stipulations in
force.
NOTE
Check the connections, main voltage and phase
voltage before the machine is started, to pre-
vent damage to the air treatment unit’s elec-
tronics.
Miniature circuit-breaker
The air treatment unit’s operating circuit and some of
its internal components are fused internally by a mini-
ature circuit breaker (FC1).
Accessibility, electrical connection
The plastic cap of the electrical boxes is opened using a
screwdriver.
NOTE
The cover for the input card is opened without
