Electrical connections
Danger
Electromagnetic radiation near the wiring cham-
ber of the heat pump control unit can interfere
with electrical devices such as heart pacemak-
ers and defibrillators.
■ Wearers of heart pacemakers:
Avoid immediate proximity to the wiring cham-
ber of the heat pump control unit. If necessary,
consult a doctor beforehand.
■ Store and use defibrillators outside the area at
risk.
Danger
Incorrect electrical installations can lead to seri-
ous injury from electrical current and result in
appliance damage.
Connect the power supply and implement all
safety measures (e.g. RCD circuit) in accord-
ance with the following regulations:
■ IEC 60364-4-41
■ VDE regulations
■ TAR medium voltage VDE-AR-N-4110
Danger
Contact with live components can lead to seri-
ous injury from electric current. Some compo-
nents on PCBs remain live even after the power
supply has been switched off.
■ Switch off the power supply to the system (e.g.
at a separate fuse or mains isolator). Check
the system is isolated from the power supply
and safeguard against reconnection.
In addition to the control circuit there may be
several power circuits.
■ Prior to removing the heat pump covers, wait
at least 4 minutes until the voltage has drop-
ped out.
■ Never touch terminal areas of the heat pump
control unit or power connections (see
page 36).
Danger
The absence of component earthing can result
in serious injury from electrical current and in
component damage in the event of an electrical
fault.
■ Restore all protective conductor connections
of the heat pump.
■ The heat pump and pipework must be groun-
ded to the equipotential bonding of the build-
ing.
