4.5. Heat Source Pump Connection
The line cross section for the connection of the brine
circuit or ground water pump must be sized according
to technical data.
It is possible to connect both single-phase and three-
phase brine circuit or ground water pumps.
In the case of single-phase brine circuit or ground
water pumps, the terminals 7/L; 10/N; 11/Pe are used
for connection.
The motor protection for brine/ground water pump
must be carried out on-site.
4.6. EMC
Please take note of the following with regard to this is-
sue: Electro-Magnetic Compatibility (EMC) demands
additional work and expertise from all manufacturers
and operators of modern electrical technology and
electronics year on year.
As the number of electronic devices in use increases
continually, the number of potential sources of inter-
ference also increases. A combination of cables from
the power supply company, transmission stations and
other communications devices generate an invisible
“electrosmog".
This interference affects all systems, both biological
(us as living beings) as well as technical electrical
systems. They generate undesirable fault currents
which can have different effects.
The effects on biological systems can only be guessed
at currently, but the effects on technical electrical sys-
tems are measurable, and in the worst case, visible
as well.
The faults can have different effects:
- Short-term measurement faults
- Permanent measurement faults
- Short-term interruption in data connections
- Permanent interruption in data connections
- Data losses
- Damage to equipment
Potential sources of interference are essentially all
technical electrical systems, e.g. contactor coils,
electric motors, transmitters, mains and high-voltage
lines, etc., and the equipment can be affected via dif-
ferent coupling routes (galvanic, inductive, capacitive,
via radiation).
As far as we are concerned, everything has been
done to protect the Navigator Control from interfer-
ence (Hardware design, EMI-proof electrical panel,
network fi lter, etc.). In particular, it is the responsibility
of the electrician to prevent possible coupling paths
when setting up the electrical installation.
