Terminal Connections
See the wire size and terminal torques specifications on page 290 .
Digital outputs are connected to these terminals.
For connection of a load, the reference pole L- of the channel group
must be used. Although L- at terminals 7 and 12 and at terminals 13
and 18 are connected internally to L- on the power supply input, it is
strictly recommended to use 7 and 12 for outputs 1…4 only and 13
and 18 for outputs 5…8 only. EMC testing was performed in this
manner.
