Safety barrier type 146
The safety barrier type 146 is used for fastening on
carrier rail 35 x 7,5 mm (C-profile) acc. to EN 50 022.
VEGATRENN 546
VEGATRENN 546 is designed as module card in
European size (DIN 41 612) and for mounting into the
VEGA 19"-carrier BGT 596 Ex.
Coding
(only for VEGATRENN 546)
A mechanical coding in form of a pin in the multipoint
connector and a hole in the multipoint plug ensures
that in case a module card is exchanged, only the
correct card type is inserted. The pin (attached) is
supplied with the module and must be inserted into
the card specific position in the hole when the module
is installed.
A function coding with fixed coded pin ensures that Ex
and not-Ex- module cards are not exchanged.
