VEGA VEGATOR 256C - Manual (Page 10)

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
l
If overvoltage surges are expected, overvoltage arresters
should be installed
Tip:
We recommend VEGA overvoltage arresters B61-300 (power
supply VEGATOR 256C) and B62-36G (sensor supply).
You can find detailed information on the power supply in
chapter "Technical data" in the "Supplement".
Power supply of VEGATOR 256C is connected with standard
cable according to the national installation standards.
Standard two-wire cable without screening can be used to
connect sensors. If electromagnetic interference is expected,
screened cable must be used.
From a cable length of 50 m use one cable for each signal
conditioning instrument.
If you want to use a common cable, the min. and max. cables
must be screened. The screen must be connected to ground
on both sides.
