5 .1 Preparing the connection
Always keep in mind the following safety instructions:
l
Connect only in the complete absence of line voltage
Connect the power supply according to the following diagrams.
Oscillator KONE60R is designed in protection class 1. To
maintain this protection class, it is absolutely necessary that
the ground conductor be connected to the internal ground
terminal. Take note of the general installation regulations. As a
rule, connect VEGAKON 66 to vessel ground (PA), or in case
of plastic vessels, to the next ground potential. On the side of
the housing there is a ground terminal between the cable
entries. This connection serves to drain off electrostatic
charges.
The data for power supply are stated in chapter "Technical
data" in the "Supplement".
VEGAKON 66 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.
If cable with a different diameter or wire cross section is used,
exchange the seal or use an appropriate cable connection.
5 .2 Connection instructions
Danger:
