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 type 03, 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.
