6.1 Device connection
Important information
Prerequisites
•
E
lectrical installation is carried out according to the project planning.
•
Dangerous condition of the machine is and remains off during the electrical instal‐
lation.
•
Electrical installation is done in conformity with IEC60204-1.
•
The mounting rail is connected to the functional earth.
•
The safety outputs and external device monitoring (EDM) must be wired within the
control cabinet.
•
When using the safety relay with voltages larger than the safety extra-low voltage:
The N/C contacts of the controlled contactors must be safely isolated from the
other contactor contacts.
•
Enabling current paths are safely isolated from the other terminals. There is a
basic insulation between the enabling current paths.
•
The ground connection of all connected devices must have the same potential as
A2.
•
All connected devices and the reset pushbutton comply with the required category
in accordance with ISO 13849-1 and SIL in accordance with IEC 62061 (e.g.
shielded single sheathed cables, separate installation).
