VEGA VEGAKON 61 - Transistor (NPN_PNP) - Manual (Page 11)

5 Connecting to power supply
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 operating voltage according to the following connection
diagrams. The electronics module KONE60T 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.
The data for power supply are specified in chapter "Technical data".
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas, screened cable should be
used.
Use cable with round cross-section. A cable outer diameter of 5 … 9 mm
(0.2 … 0.35 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.
5 .2 Connection instructions
Danger:
Switch off power supply before starting connection work.
Connect mains voltage according to the connection diagrams.
