*) The 0 V terminals are directly connected to each other. 0 V is indirectly connected to "Power contact 0 V" for the purpose of potential definition (resistor several 100 Ohm), the connection is not current carrying!
**) The +10V connections are not connected to each other so that a short circuit etc. can be diagnosed on a channel-by-channel basis. A connection on the system side is not recommended.
