Always keep in mind the following safety instructions:
•
Connect only in the complete absence of line voltage
•
If overvoltage surges are expected, overvoltage arresters should
be installed
•
Only for use in non-hazardous areas
The instrument is connected with standard two-wire cable without
shielding.
Use cable with round cross-section. A cable outer diameter of
5 … 10 mm (0.2 … 0.39 in) ensures the seal effect of the cable gland.
If you are using cable with a different diameter or cross-section,
exchange the seal or use a suitable cable gland.
The ON/OFF position switches are already mounting and connected
in the terminal housing to the terminals.
Connect the ON/OFF position switches according to the following
diagrams. Take note of the general installation regulations. As a rule,
connect VEGASOURCE 86 to vessel ground (PA), or in case of plas-
tic vessels, to the next ground potential.
The data for power supply are specified in chapter "
Technical data ".
