NOTE!
Terminals are not all located on the same PCB.
In rare cases, very long control cables and analog signals
may, depending on installation, result in 50/60 Hz ground
loops due to noise from line power supply cables.
If this occurs, it may be necessary to break the shield or
insert a 100 nF capacitor between shield and chassis.

NOTE!
To comply with EMC emission specifications, shielded
cables are recommended. If a non-shielded cable is used,
see
4.5.15 Unshielded Control Wires
. If non-shielded control
cables are used, it is recommended to use ferrite cores to
improve EMC performance.
