Table 6.4 Terminal Connections
Very long control cables and analog signals may, in rare
cases and depending on installation, result in 50/60 Hz
earth loops due to noise from mains supply cables.
If this occurs, break the screen or insert a 100 nF capacitor
between screen and chassis.
NOTE
The common of digital / analog inputs and outputs should
be connected to separate common terminals 20, 39, and
55. This will avoid ground current interference among
groups. For example, it avoids switching on digital inputs
disturbing analog inputs.
NOTE
Control cables must be screened/armoured.
