6 Electrical connection
6.1 Preparation
CAUTION!
Before starting any wiring, isolate the
heating system from the power
supply.
DANGER of electric shock
All electrical connection and
installation work must be carried out
according to the relevant national and
regional regulations.
Connection work may only be carried
out by an approved contractor
according to this manual!
The listed fuse protection ratings and cable cross-
sections are guideline values only! The electrician
connecting up the heat pump is responsible for
selecting the correct safety devices. Cables should
be selected by the electrician taking into account
the output and cable lengths.
WARNING
Before commissioning, the necessary
fault protection measures on the
system and the earth connection must be checked
by a certified electrician.
The main power circuit
for the compressor motor has no upstream
power contactor on the machine side.
Control
devices and equipment to disconnect and shut
down all supply voltages across all poles, which
must be provided on the system side, must meet
the technical safety requirements of
EN 60204-1
sections 5 and 13.4.5 , as well as the international
regulations in the IEC 60947 series.
During maintenance or service work, shut down all
heat pump supply voltages on the system side and
observe safety regulations to EN 50110-1.
Failure to observe the technical safety
requirements or precautions may result in serious
injury or death.
Checklist:
•
The specified voltage must be consistent with
the grid voltage. Pay attention to the
information on the type plate!
•
For connection of the appliance, approval
must be obtained from the relevant power
supply utility.
•
Fuse protection for the main power circuit
230 V/400 VAC should be provided via a
circuit breaker, which triggers a shutdown
across all poles in the event of a fault.
•
If RCDs (FI) are used, they must trigger an
AC/DC-sensitive shutdown.
•
The supply lines must be protected against
surges and short circuits.
•
It is essential that the regulations of the
responsible PSU (power supply utility) and
the applicable EN standards are observed.
