9.2 Interferences

If errors cannot be corrected with the following instructions please contact the manufacturer (see last page).
NOTE
Device, connection cables and signal cables must not be installed
directly next to interference, which have strong inductive or capacitive
interference or strong electrostatic fields!
External interference can be avoided by a suitable cable routing.
Signal wires and cables are principally laid separately from the
LASTSTROMLEITUNG and keep a safety distance of at least 0,5m to
inductive or capacitive interference sources such as contactors, relays,
motors, switching power supplies, clocked controllers, etc.!
If faults occur despite of compliance of all the described items above,
it must proceed as follows:
1. Attachment of RC elements of contactor coils of AC
2. Attachment of free-wheeling diodes using DC inductors
3. Attachment of RC elements of individual motor phases (in the
4. Do not connect safety ground and reference potential
5. Pre-connecting a mains filter on the external power supply
6. Use of sheet metal or metalized shielding housings
contactors (e.g. 0.1 μF / 100Ω)
terminal box of the engine)
