6.3. EMC compatibility
Some remarks regarding problems with EMC: Elec-
tromagnetic compatibility requires all manufactures
and operators of modern electrical engineering and
electronics to invest higher amounts of money and
more know-how from year to year.
As the number of electronic devices in use is con-
tinuously rising, the number of potential disturbance
sources also rises. Together with the lines of the
energy supply companies, of transmission equipment
and other communication facilities §electromagnetic
pollution" that is invisible for us is created.
These disturbances have an e
ff
ect on all systems, not
only on biological (on creatures), but also on electro-
technical systems. They lead to undesired error
fl
ows
which can have diverse e
ff
ects.
The e
ff
ects on biological systems are extremely di
ffi
-
cult to fathom, the e
ff
ects on electrotechnical systems
are, however, measurable, and in the most unfavor-
able case also visible.
The disturbances can have various e
ff
ects:
- Short-term measurement errors
- Long-term measurement errors
- Short-term interruption of data connections
- Long-term interruption of data connections
- Data loss
- Damage to the equipment
In principle, all electrotechnical systems can repre-
sent possible sources of interference, e.g. contactors,
electric motors, transmitters, line voltage or high
voltage lines, etc. whereby the in
fl
uence of the equip-
ment can take place on the various coupling paths
(galvanic, inductive, capacitive, by radiation).
We have undertaken everything possible to make the
navigator regulation as fail-safe as possible (hard-
ware design, EMC--proof control panel, network
fi
lter
etc). It now lies within the
fi
eld of responsibility of the
electrician in setting up the electronic installation to
avoid possible coupling paths.
6.4. Lightning protection and potential compensation
An 11 mm bore is found on the base plate of the
refrigeration part at the opening for the hydraulic
feedthrough. If required, lightning protection or equi-
potential bonding can be connected here.
If a heating element is used as a bivalent
system, the supply line must be laid by
the customer. The supply of the heating
element is not carried out via the electri-
cal cabinet.
