Table 5.5: 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.
NB!
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.
NB!
Control cables must be screened/armoured.
5.1.26 How to Test Motor and Direction of Rotation
Note that unintended motor start can occur, ensure no personnel or equipment is in danger!
