The following condition is also reported in RM mode:
Ring redundancy guaranteed. By default, there is no ring redundancy
monitoring
2.1.10 Connecting the terminal blocks, start-up procedure
Pull the terminal block off the device and connect the voltage supply lines
and the signal lines.
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.
