Scenario 1
If the PE of the actuator is done only via the PE conductor of the
motor cable, the maximum permissible cable lengths for the
electronic units EAS822 and EBS852 are reduced in accordance
with the following table.
The maximum permissible shutdown time of 200 ms in case of a
fault is complied with in the process.

Scenario 2
By laying an extra potential equalization conductor between the
electronic unit and the actuator, with a small conductor cross-
section of the motor cable (e.g. 1.5 mm
2
), the maximum
permissible cable length can be increased.
The ground resistance of the potential equalization conductor
must be < 0.1
Ω
.
The maximum permissible shutdown time of 200 ms in case of a
fault is complied with in the process.

Scenario 3
If the cable lengths specified in
Actuator assignment and
maximum cable lengths
on page 20 are fully utilized, an
additional protective potential equalization must be connected.
To do this, the electronic unit and the actuator must be
connected via a short cable with a minimum cross-section of
4 mm
2
(12 AWG) to the on-site potential equalization.
The installation regulations for setting up grounding systems
must be observed and followed.
