4．Connections

・ Using twisted pairs for I/O and routing them separately from output load wire is ideal to minimize noise interference.

・ For improved noise filtering, add lower value of electrolytic capacitor (Section 2-11, 47µF)

・ Minimize length of output load wiring.

・ Connect FG terminal with earth ground of system using power supply using minimal length possible.

・ Recommended tightening torque for M4 terminal screws is 1.4Nm/1.03lbft

・ To minimize noise interference, be sure to separate the output load line, remote control line, and remote sensing line from

the input line. Noise immunity can be also improved by twisting each line.

・ Attaching a small volume electrolytic capacitor to the load end is also effective to eliminate noise.

・ For safety and noise prevention, ensure a secure grounding connection from ground terminal to equipment enclosure using

appropriate wire size. Otherwise, it may cause electric shock.

・ Recommended tightening torque for M4 I/O terminal screws: 1.4Nm

・ Shut off the power, and carefully make connections for the remote sensing function. Incorrect wiring or poor connection could

cause malfunction.

・ Be sure to use each terminal (pole) of the terminal block at 20A or less.

・ For the loading current of 20A or larger, use two terminal poles at the same time.

5．Troubleshooting

・ Confirm input AC voltage to be within spec of 100-240VAC/50-60Hz.

・ Confirm all input and output connections are in accordance with above.

・ Check the output adjustment potentiometer. Sometimes output OVP function turns off the output power when the potentiometer

is adjusted too high.

・ Please note that an excessive capacitive load can create over current situation.

・ Confirm remote on/off is getting the appropriate voltage for desired operation.

・ Before suspecting a failure.

・ Check if the rated input voltage is connected.

・ Check if the input/output wiring is appropriate.

・ Check if the wire material is not too thin.

・ Check if a large-capacity capacitor is not connected to the load side.

・ Check if the remote control is not active.

・ Check if the accessory connector for CN501 is connected.

The accessory connector is required if the remote sensing function is not used.

・ Check if forced air cooling by external fans is properly functioning.

6．Warranty
