Wiring Connections
Warning
All power must be switched
off before connecting or
disconnecting any plugs
WARNING: Electromagnetic Compatibility (EMC)
It is necessary to ensure that the unit is wired up in accordance with the connection arrangements shown above.
For effective protection the user’s electrical cabinet, the valve subplate or manifold and the cable screens should be
connected to efficient ground points.
In all cases both valve and cable should be kept as far away as possible from any sources of electromagnetic
radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc. Difficult
environments could mean that extra screening may be necessary to avoid the interference.
