Cable glands

The actuators and electronic units are supplied without cable
glands. Suited cable glands must be installed on site.

Selection of suited connection cables

Please observe the following information when selecting cables:
• Use shielded cables for the motor/brake cable, the sensor
cable, and the signal cable to the control system/controller.
• Connect the shielding of the motor/brake cable and the
sensor cable on both sides (to the actuator and to the
Contrac electronic unit).

Potential equalization

In order to avoid the risk of an electric shock, it must not be
2
(12 AWG)
possible to come into contact with dangerous live parts and
2
(16 AWG)
conductive parts that can be touched should not become
2
(16 AWG)
dangerous live parts either under standard conditions or under
2
(12 AWG)
conditions when a single fault occurs.
2
(16 AWG)
The actual current flowing in the event of a fault is obtained
from the phase to ground voltage and the total impedance
present in the fault circuit.
For long cables, the voltage drop may be dangerous to come
into contact with high current flowing.
Preferably, the electronic unit and the actuator must be
2
(12 AWG)
connected with low resistance (ground resistance < 0.1 Ω) to the
2
(16 AWG)
potential equalization.
2
(16 AWG)
In the process, the respective standards of the VDE 100 series
2
(12 AWG)
must be observed.
