Connecting the terminal blocks, start-up procedure

 Pull the terminal block off the device and connect the voltage supply lines
and the signal lines.
Terminal blocks on MS20/MS30-...A... and MS20/MS30-...C...

Products with voltage range A or C (product code position 15—see
table 1) have two 4-pin terminal blocks.
Note: The maximum accaptable wire size for the terminal blocks is
