Wiring Wire Requirements • Use the terminals that comply with the specifications given below. • Set terminal wiring torque to from 5 to 7kgfcm. • Use wiring cables of #16 to #22 AWG. Terminal size = 6.35 mm (0.25 in) or less L = 6.35 mm (0.25 in) or less Solderless terminal Wiring torque...
Power Supply Wiring Make sure to connect to the controller system a stable power that has voltage fluctuations within 10% deviation from the rated input voltage. The frame ground terminal must be grounded with Class 3 (100 or less of ground Ω...
• Using a two-wire sensor may needs an additional circuit configuration so that total current consumption does not exceed the allowable current consumption. • For all NX7 and NX7s controllers, all the commons on the input terminal block are isolated internally each other.
IMPORTANT • “NC” terminals are not intended for use as connection points. • For all relay output controllers (NX7-xxxxR and NX7s- xxxxR controllers), all the commons on the output terminal block are isolated internally each other. • For all transistor output controllers (NX7-xxxxT and...
