4.1 Preparations for Inteference-free Operation
In the following section we have compiled some general information
for you that is important for trouble-free operation. If you are already
acquainted with this topic, you can skip to the next section. There, you
will learn about which conditions are necessary for installing the
gateway.
Cable routing
Route your cables separately in cable groups. This will protect your
gateway from any unintended electromagnetic interferences.
The following groups should be routed separately from each other:
Group
Line
A
Data and power supply lines for:
DC voltage below 60 V
AC voltage below 25 V
B
Data and power supply lines for:
DC voltage between 60 V and 400 V
AC voltage between 25 and 400 V
C
Power supply lines above 400 V
– You can route cables of the same group together in cable ducts or bun-
dles.
– Cables of group A and B:
– Route the groups in separate bundles or
– in cable ducts at a minimum distance of 10 cm from each other.
– Cables of group C
– Route the groups in separate bundles or
– in cable ducts at a minimum distance of 50 cm from the other
groups.
Shielding
Shield your cables. This will reduce any unintended electromagnetic
interferences.
Potential equalization
Potential differences occur when devices are connected to different
earths. These potential differences cause malfunctions.
