24 V I/O available for customer connections at:
XT.31.2 24 V (via 2 A fuse)
XT.31.1 for own fuses, max. fuse size is 2 A to ensure breaking at short circuit
Note! DSQC 374 can not trip any fuses.
XT.31.4 0 V (connected to cabinet structure)
3.13.2 115/230 V AC supply
The robot has a AC supply available for external and internal use.
This voltage is used in the robot for supplying optional service outlets.
The AC supply is not galvanically separated from the rest of the controller voltages.
Technical data
Voltage 115 or 230 V
Permitted customer load Max. 500 VA
Fuse size 3.15 A (230 V), 6.3 A (115 V)
AC supply is available for customer connections at:
XT.21.1-5 230 V (3.15 A)
XT.21.6-8 115 V (6.3 A)
XT.21.9-13 N (connected to cabinet structure)
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.
Technical data:
Potential difference to chassis earth: Max. 60 V continuous
Max. 500 V for 1 minute
Permitted supply voltage: I/O units 19 - 35 V including ripple
panel unit 20.6 - 30 V including ripple
