Note 1: Unused channels shall basically be opened when the voltage output module is used or short-circuited when the
current output module is used.
Note 2: Shielding wires shall be grounded basically on the external device side (class D grounding). When shielding wires
are grounded on the analog output module side (class D grounding) due to the condition of external noise, NC
terminals can be used as dummy termination for shielding wires. However, they must not be used as dummy
termination for other control signal cables or power cables.
Note 3: Keep signal wires that go out of this module sufficiently away from high-voltage or power cables, and avoid parallel
wiring.
Note 4: Avoid wiring the signal cables in the vicinity of load cables coming from devices other than PLC or bundling them with
such cables.
Note 5: Keep the signal cables sufficiently away from circuits where high frequencies occur, such as inverter main load circuit.
