Connection to the PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals; however, the USB ground
connection is not galvanically isolated from ground. Use only an isolated laptop as PC connection to the USB connector on the drive.

When using a contactor with a DC coil inside with STO, it is important to make a return way for the current from the coil when turning it off. This can be done by using a freewheel
diode (or, alternatively, a 30 V or 50 V MOV for quicker response time) across the coil. Typical contactors can be bought with this diode.
All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
10.6.3 Control Card, 24 V DC Output
Terminal number XD2.10, XD2.11
Output voltage 24 V +1, -3 V
Maximum load 200 mA
The 24 V DC supply is galvanically isolated from the supply voltage (PELV), but has the same potential as the analog and digital inputs
and outputs.

Terminal number XD2.6
Output voltage 10.5 V ±0.5 V
Maximum load 15 mA
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
10.6.5 Digital Outputs
Programmable digital/pulse outputs 2
