2.1.1 Earthing the end plates
The valve terminal possesses both a left−hand and a right−
hand end plate as a mechanical termination of the valve ter
minal. These end plates fulfil the following requirements:
they comply with protection class IP 65.
they contain connections/contacts for earthing.
they contain holes for fitting the valve terminal onto a wall
and, in the case of type03, also for the hat−rail clamping
unit.
Please note
When supplied from the factory, the end plates of the valve
terminal are earthed internally. If you wish to extend/con
vert the type 03 valve terminal, earth the end plates of the
valve terminal as described below.
You thereby avoid faults caused by electromagnetic in
fluences.
Earth the end plates after extension/conversion as follows:
1. Right−hand end plate (type 03):
In order to earth the right−hand end plate, connect the
ready−fitted cable on the inside to the appropriate con
tacts on the pneumatic modules or on the node (see
diagram below).
2. Left−hand end plate:
The left−hand end plate is connected conductively to the
other components by means of the ready−fitted spring
contacts.
Remark:
Instructions on earthing the complete valve terminal can be
found in the chapter Installation".
The diagram below shows how the end plates are fitted using
as an example a type 03 valve terminal.
