Mounting procedure
Prerequisites
Mounting is done in accordance with EN 50274 and electrical installation in
•
accordance with IEC 60204-1 in the control cabinet with enclosure rating
IP54.
•
Mounting is done on a 35 mm mounting rail (IEC 60715).
The mounting rail is connected to the functional earth.
•
•
The safety relay is installed in a vertical orientation (on a horizontal mounting
rail).
•
There is at least 50 mm of space for air circulation above and below the
safety relay.
•
There is at least 25 mm of space in front of the safety relay (front side). More
space may be needed depending on the connections.
Approach
Attach safety relay to mounting rail.

Device connection
Prerequisites
•
Contact fuse with safety fuse gG or circuit breaker C: 6 A, maximum short-
circuit current I ≤ 400 A
•
The ground connection of all connected devices must have the same poten‐
tial as A2.
•
All connected devices and the reset pushbutton comply with the required
category in accordance with ISO 13849-1 and SILCL in accordance with IEC
62061 (e.g. shielded single sheathed cables, separate installation).
