3.1 Connection instructions
Danger
Switch off the power supply before starting
connection work.
The electrical connection must be carried out
in accordance with the integrated oscillator
version. Connect mains voltage acc. to the
following connection plans.
Note
Give attention when replacing the housing
cover that the inspection glass is above the
control lamp (LED).
Note
If strong electromagnetic interference is ex-
pected, we recommend the use of screened
cable. The screening of the cable should only
be earthed only on the sensor end (elec-
trode).
As a rule, connect VEGACAP with vessel
ground (PA). To do this, use the ground ter-
minal on the housing (VEGACAP 27, 35 and
98) or the thread on the hexagon surfaces of
the mounting boss (screw
M4 x 5). On VEGACAP 97 terminal 3 must be
connected. This connection is used to draw
the ground potential as well as to drain off
electrostatic discharge. 1 Housing cover
