Tightening torque for the
retaining screws in the case of
block mounting
1.8 Nm ± 15%
In the case of block mounting,
the shield clamp makes full
contact with the base of
the housing (cable diameter
12 mm)
Minimum tightening torque
with larger cable diameter
(
>
12 mm … 23 mm)
0.5 Nm ± 15%
With a higher tightening
torque, make sure that the
connecting cable does not get
crushed in the clamping area
due to excessive pressure.

•
Connect all shields to the PE over a wide surface area on the motor side,
e.g. via the shield connection provided on the motor connector or the shield
support surface in the motor junction box.

[X9A], power supply and DC link circuit connection
The connections for the power voltage supply and the DC link circuit are not
protected against wiring errors. The reversal of the connections results in a device
defect during switch-on.
With cross-wiring, observe the polarity of the DC link connection on all devices.

[X9C], logic voltage supply
WARNING
Risk of injury due to electric shock.
• For the electrical power supply with extra-low voltages, use only PELV circuits
that guarantee a reinforced isolation from the mains network.
• Observe IEC 60204-1/EN 60204-1.
•
Only connect PELV circuits with an output current of max. 25 A. Otherwise,
use a separate external fuse: 25 A.
