for robot control
General
CAUTION!
Risk of damage to standard I/O connection (X1) supply due to overcurrent.
Secure supply against overcurrent with a 500 mA slow-blow fuse.
NOTE!
To avoid malfunction, keep the cable length between the cleaning device and robot 
control as short as possible.
The standard I/O (X1) connecting plug for connecting the cleaning device to the robot con-
trol is part of the scope of supply. The cable harness must be adapted to the connection 
technology on the robot control.
