5.1 Safety
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.
Comprehensive information concerning the electrical installation of the device è Manual Assembly,

Information for operation with safety functions
NOTICE
Check the safety functions to conclude the installation process and after every modification to the
installation.
During installation of safety-related inputs and outputs, also observe the following:
–
Comply with all specified requirements, e.g.:
–
Surrounding area (EMC)
–
Logic and load voltage supply
–
Mating plug
–
Connecting cables
–
Cross-wiring
–
Additional information
è
Manual Assembly, Installation.
–
The maximum permissible cable length between the safety relay unit and the plug of the I/O
interface is 3 m.
–
Comply with the requirements of EN 60204-1 for the installation. In the event of a fault, the voltage
must not exceed 60 V DC. The safety relay unit must switch off its outputs in the event of a fault.
–
Install wiring between the safety relay unit and the I/O interface of the servo drive in such a way as
to eliminate the risk of a short circuit between the conductors or to 24 V, as well as a cross circuit
è EN 61800-5-2, Annex D.3.1. Otherwise, the safety relay unit must feature detection of shorts
across contacts and, in the event of a fault, must switch off the control signals on 2 channels.
–
Use only suitable mating plugs and connecting cables è Manual Assembly, Installation.
–
Prevent conductive contamination between neighbouring plug pins.
–
Make sure that no bridges or similar can be inserted parallel to the safety wiring. For example, use
the maximum wire cross section or appropriate plastic wire end sleeves.
–
Use twin wire end sleeves for cross-wiring safety-related inputs and outputs. A maximum of 10
devices may be cross-wired when cross-wiring inputs and outputs
è Manual Assembly, Installa-
tion.
–
The safety relay unit and its inputs and outputs must meet the necessary safety classification of the
safety function that is required for the specific case.
–
Connect each of the control inputs to the safety relay unit on 2 channels using parallel wiring.
