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.
