Heat pump installation instructions
10 Electrical installation
Establish the electrical connection between
the heat pump module and the compact
module.
1. Route the two plug-in connections of the load and
bus cable from the compact module to the plug-in
points on the heat pump module.
2. Couple the connectors together.
3. Fit cover for plug-in connections.
Connect the electrical cables
ATTENTION
Irreparable damage to the compressor due to wrong
rotating field!
► Ensure that there is a clockwise rotating field for
the compressor load infeed.
Basic information on the electrical connection
●
The specifications of the local energy supply
company may apply to electrical connections.
●
Fit the power supply for the heat pump
with an all-pole miniature circuit-breaker
with at least 3
mm contact spacing (per
IEC 60947-2).
●
If required: Residual current circuit breaker type A
is sufficient.
●
Note the level of the tripping current
(
“Technical data/Scope of supply” on page
23).
●
Comply with the electromagnetic compatibility
regulations (EMC regulations).
●
Lay the control/sensor cables and unit supply
cable sufficiently far apart (> 100 mm).
●
Lay unshielded power supply cables and shielded
cables (bus cable) sufficiently far apart.
●
Do not lengthen the patch cable or the bus cable.
Bus cables up to 30 m long can be used if the
quality of the cable is the same as that of the
original cable.
Electrical connection
The electrical connection is established via the
compact module switch box.
Pull in the cables and conductors and make the
connections
1. Strip the sheathing of all cables to the external
loads before laying in the cable gland of the
control box.
2. Route the cable through the cable gland and into
the switch box.
NOTE
Cables must have adequate excess length.
