2.2.3 Fitting the right−hand end plates with Midi/Maxi valves
Note
With Midi/Maxi valves, the right−hand end plate is earthed
internally when the valve terminal is supplied from the
factory. If you under take extensions/conversions to the
valve terminal, earth the right−hand end plate of the valve
terminal as described below.
In this way, you will avoid interference from electromagne
tic sources.
Earth the end plates
after extension/conversion as follows:
1. Right−hand end plate (Midi/Maxi):
In order to earth the right−hand end plate, connect the
cable fitted on the inside onto the appropriate contacts of
the pneumatic module or the CPX bus node (see Fig.2/8).
2. Left−hand end plate:
The left−hand end plate is connected conductively with
the other components by means
of rails in the interlinking
block.
Instructions on earthing the entire valve terminal can be
found in section 3.1.5. Fig.2/8 shows you how to fit the
right−hand end plates with Midi/Maxi valves.
