Digital Output Terminals
Terminals accommodate wires up to 1.5 mm
2
(16 AWG). Digital outputs are
connected to the following terminals:
For connection of a load, the reference pole L- of the concerned channel group
must be used (2-pole connection). Although L- at terminals 1 and 6 and at 7 and 12
is connected internally to L- on the power supply input, it is strictly recommended
to use 1 and 6 for outputs 1 through 4 only and 7 and 12 for outputs 5 through 8
only. EMC testing was performed in this manner.
