Description of the hardware
5.3 Connecting/wiring
Modular Safety System 3RK3
76 System Manual, 10/2008, 926 2530-02 DS 02
5.3.6 Connecting the system interfaces
CAUTION
EMC measures
Unused system interfaces must be closed using system interface covers.
CAUTION
Off-circuit installation
Connect the system interfaces only in a voltage-free state!
If you connect system interfaces while the system is connected to the power supply, this
can damage the safety components which, in turn, means that the safety function is no
longer available.
Note
Connection cables
• MSS system components are connected via the system interfaces using connection
cables.
• The connection cables are available as adjacent versions (0.025 m). Connection cables
up to max. 2.5 m in length are available for connecting to the diagnostics module.
Note
Reverse polarity protection
Please observe the color coding and mechanical coding on the connection cables.
