2.10 Connecting the terminal blocks, start-up
procedure
 Pull the terminal block off the device and connect the voltage supply lines
and the signal lines.
2.10.1 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 2.5 mm
2
(0.004 in
2
) or AWG 12.
