• Wires connected to
– supply terminals,
– outputs NC, NO, C and
– start/stop inputs, A, Y, B, MIN,
MAX, 10 V
must be separated from each other
and from the supply by reinforced
insulation.
• All wires connected to a terminal
block must be tied up at the
terminals.

Note:
• If the 0-10 V input is used, there must be a connection across terminals MIN and
must be closed).
• All cables used must be heat-resistant up to +85 °C.
• All cables used must be installed in accordance with EN 60204-1 and EN 50174-2: 2000.
Concerning demands on signal wires and signal transmitters, see section 11. Technical data.
