Observe the following precautions
•
The FC 302 with MCB 108 (including the connections between X31/9 and Terminal 37) must be placed inside an
IP54 enclosure.
•
Safe Stop activation (i.e., removal of 24 V DC voltage supply to terminal 37 by removing voltage to dual pole input
of MCB 108) does not provide electrical safety.
•
The safety device connected to the dual pole input of the MCB 108 must fulfill the requirements of cat. 3 / PL d
according to ISO 13849-1 for interrupting the voltage/current to the MCB 108. This also applies for the connections
between the MCB 108 and the safety device.
•
Read and follow the instructions for the safety device to connect it properly to MCB 108.
