N O T I C E
All signals to the safety option must be PELV supplied and comply with EN IEC 60204.
Follow these guidelines to ensure 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 shields at both ends to the grounded enclosures through a good electrical connection and through a large surface area.
• Connect cable shields as close as possible to the cabinet cable entry.
• If possible, intermediate terminals should not interrupt cable shields.
• Retain cable shields for both power cables and data cables using the appropriate EMC clamps. Ensure that the shield connection
for control cables has a low induction.
N O T I C E
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.
