4.5.1 Cabling Requirements
CAUTION
If a short circuit occurs, it is no longer possible to switch
off the frequency converter with terminal 37.
NOTICE
All signals to safety option must be PELV supplied and
comply with EN IEC 60204.
Follow these guidelines to ensure a proper wiring:
•
Use appropriate wiring to prevent short circuits
to a supply line or between the inputs.
•
Use separate multi-core cable for supply voltage
to avoid short circuits between the cable from
the output (S37) and the 24 V DC supply line.
•
Connect screens at both ends to the grounded
enclosures through a good electrical connection
and through a large surface area.
•
Connect cable screens as close as possible to the
cabinet cable entry.
•
If possible, intermediate terminals should not
interrupt cable screens.
•
Retain cable screens for both power cables and
data cables using the appropriate EMC clamps.
Ensure that the screen connection for control
cables has a low induction.
NOTICE
If short circuits and cross circuits can be expected with
safety-related signals, and if they are not detected by
upstream devices, protected cable installation is required
as per EN ISO 13849-2.

4.5.3 Wiring Procedures
1.
Remove the jumper wire between control
terminals 37 and 12/13 (24 V).
NOTICE
Cutting or breaking the jumper is not sufficient to avoid
short circuiting.
