Product description
2 Mounting
Coding
To avoid interchanging of Ex and not-Ex-signal
conditioning instruments, the plug-in and
terminal socket must be provided with a coded
key (attached to consignment) when Ex-instru-
ments are used. Insert the coded key with flat
pliers to the position between plug numbers
b22/d22 and b24/d24.
Hence only an Ex-suitable instrument can be
inserted into this module.
Plug-in socket, view to the plug surface
Screwing of the plug-in socket
Screw the plug- in socket with a long 4 mm
screwdriver such into the housing, that the
plug side points to the inside of the housing
and number two of the plug-in and terminal
socket is on top (at the earth screw).
