NT20M Power Supply Wiring
•
Provide 24-VDC power.
•
Use a power supply within the allowable voltage range.
Power supply voltage
Allowable voltage range
24 VDC
20.4 to 26.4 VDC
•
Use a power supply with a rated capacity of at least 15 W at 24 VDC.
•
If power lines are long, then use wires of at least 2 mm
2
to avoid a drop in
voltage.
•
Use twisted-pair cables.
•
Turn off the power before wiring.
•
Be careful not to reverse the positive and negative terminals.
•
Do not run the wiring between the 24-VDC power supply and the PT power
supply input terminal parallel to or in close proximity with high-voltage or
high-current power lines.
•
If you anticipate noise levels exceeding specifications, use noise-prevention
measures such as installing a noise filter at the power supply. Use a com-
mon mode filter as the noise filter, and install no more than 100 mm of wir-
ing from the PT to the filter.
•
If you use a 24-VDC power supply with no output short-circuit prevention,
then wire a breaker into the circuit.
