3.2.1. PROFINET/Power connection
The SI Unit has two PROFINET communication connectors. If only one connector is used, cover the
unused connector with a seal cap so that the protection rating of IP67 is maintained.
Caution
Seal caps must be fitted to all unused bus connector ports to ensure an IP67 rating.
IP67 rating must be maintained to guarantee PROFIsafe functionality.
For reasons of EMC a secure connection to the cable shield must be established on the M12 PROFINET
connectors (BUS IN/OUT).
Power and PROFINET cables must be installed correctly.
The 24 V supply for logic (PWR connector) and the 24 V supply for the valves (PWR(V) connector) should
be protected with an external fuse.
All external supplies should have the 0 V connected to functional earth according to EN 60204-1.
A functional earth cable must be connected to the M3 terminal.
If this product is connected using power cables that are more than 30 m long or go outside of a building
then external protection devices should be added to protect against electrical surge damage.
