Note
Where possible, use separate power supplies for sensor/bus and actuator.
Total current < 9 A The total current of all modules must not exceed 9A even in
the case of series connection of the actuator supply.
Note

, depending on the length of conductor and current
load! From a certain line length of the conductor cross section is to check or adjust!
Note
Setting electronic line protection fuses.
It should be set to the safe operation a provision of 30-50% of continuous current!
However, this is again dependent on the type of backup and the power supply.
If required, additional buffer modules should be used to secure the power supply to
minimize voltage drops.
It is recommended to use power supplies with a power reserve of min. 20%!
Grounding
Note
The ground connection between housing and machine must have a low
impedance and be as short as possible.
