Preparing the connection

Note safety instructions
Always keep in mind the following safety
instructions:
•
Connect only in the complete absence of
line voltage
•
Take note of safety instructions for Ex
applications
Connect the voltage supply according to the
following connection diagrams. The electronics
module with relay output is designed in protec-
tion class I. To maintain this protection class, it is
absolutely necessary that the ground conductor
be connected to the internal ground terminal.
The data for power supply are specified in chap-
ter "Technical data".
Connection cable
VEGAVIB S 61 is connected with standard
cable with round cross section. An outer cable
diameter of 5 ... 9 mm (0.2 ... 0.35 in) ensures
the seal effect of the cable gland.
Make sure that the cable used has the required
temperature resistance and fire safety for max.
occurring ambient temperature
If cable with a different diameter or wire cross
section is used, exchange the seal or use an
appropriate cable connection.
