For connecting the valve terminal use the Festo cable
sockets type ASI-SD-FK.... You will then comply with
protection class IP65. Proceed as follows:
1. Press the AS-Interface cable into the upper part of the
cable socket.
2. Make sure that the cable is free of tension.
3. If necessary, insert the cable socket or a blanking plug
and screw it tight (max. 0.3 Nm).
Seal open flat cable ends with the Fest cable cap type
ASI-KK-FK or the cable sleeve type ASI-KT-FK. In this way
you will avoid leakage currents and comply with protection
class IP65.
