3.14 External 24 V supply

An external supply must be used in the following cases:
• When the internal supply is insufficient
• When the emergency stop circuits must be independent of whether or not the robot
has power on, for example.
• When there is a risk that major interference can be carried over into the internal
24 V supply
An external supply is recommended to make use of the advantages offered by the
galvanic insulation on the I/O units or on the panel unit.
The neutral wire in the external supply must be connected in such a way as to prevent the
maximum permitted potential difference in the chassis earth being exceeded. For example,
a neutral wire can be connected to the chassis earth of the controller, or some other common
earthing point.
