NOTE
Overcurrent due to incorrect wiring!
Failure to comply with these instructions can damage the electronic components.
Do not connect the ground of a digital signal source with a non-electrically isolated
supply to the DI- of the module.
When redundantly wired as specified in
Figure 15 and Figure 16, the modules are inserted
in the base plate next to each other and on a common connector board.
Connector boards X-CB 006 52 (with screw terminals) or X-CB 006 54 (with cable plug) can
be used.
