6 Mounting
The safety relay is intended for mounting on a DIN rail in the switch cabinet.
Prerequisites for mounting:
• Switch cabinet with appropriate degree of protection (at least IP54).
• Sufficient space on the DIN rail.
• Arrangement of the protective device acc. to EN ISO 13855 and EN 61496-2:2013 (see chapter 6.1
"Arrangement of the protective device").

Snap the safety relay onto the DIN rail.
The safety relay can be connected to the safety sensors.
6.1 Arrangement of the protective device
Optical protective devices can only perform their protective function if they are mounted with adequate
safety distance. When mounting, all delay times must be taken into account, e.g. the response times of
the protective sensor and control elements as well as the stopping time of the machine.
The following standards specify calculation formulas:
• EN ISO 13855 "The positioning of protective devices in respect of approach speeds of parts of the
human body": mounting situation and safety distances.
• EN 61496-2:2013, "Active optoelectronic protective devices": distance of the reflecting surfaces/
deflecting mirrors.

6.1.1 Calculating the safety distance
General formula for calculating the safety distance S of an Optoelectronic Protective Device acc. to
EN ISO 13855:
S [mm] = Safety distance
K [mm/s] = 1600 mm/s (approach speed for access guarding)
T [s] = Total time of the delay
C [mm] = 850 mm (default value for arm length)

Calculate the safety distance S for access guarding using the formula acc. to ISO 13855 or EN 999:
WARNING
Improper mounting may result in serious injury!
The protective function of the safety relay is only ensured if appropriately and professionally
mounted for the respective, intended area of application.

Only allow competent persons to install the safety relay.
Observe the relevant standards, regulations and these instructions.
