WARNING!
Outside the PMI (e.g. on/in the power supply and all other circuits),
appropriate measures must be taken to ensure that voltages are not
exceeded by more than 40% in the case of a transient fault (transient
protection).

Measures to protect against interference

- If necessary use bulkhead separators to protect the unit from sources of
interference.
- Inductive loads within the environment (e.g. contactor, relay and magnetic
valve coils) should be wired using suppression elements (e.g. RC
elements). This is particularly important if these inductive loads are fed
from the same supply.
- The power cable should be physically separate from the data lines
(recommended minimum distance: 10 cm/3.94"). This will avoid inductive
and capacitive interference.
- Connect the earth point to the earth conductor PE
possible copper conductor (cross section ≥ 2.5 mm
Interference voltages (supply and signal lines) and electrostatic voltages
(contact) are diverted via the earthing point.
