4 OPERATION
4.1 Checkpoints before Turning ON the Power Supply
Check the following before turning ON the power supply.
• Check that the power supply voltage is correct.
200 V class: 200 to 220 VAC, 50 Hz
200 to 230 VAC, 60 Hz
400 V class: 380 to 460 VAC, 50/60 Hz
• Make sure that the VS-656DC5 and the Inverter are connected correctly.
• Make sure that the phase sequence of the main circuit terminals (R/L1, S/L2, T/L3) and
the power supply voltage detection terminals (r1/ 11, 1/ 21, t1/ 31) are correct.
• Make sure that the VS-656DC5 control circuit terminals are connected to other control
devices correctly.
• Set the run command of the VS-656DC5 and the Inverter to OFF.
• Only turn ON the input power supply after attaching the front cover or the terminal cover. Do not
remove the cover while current is flowing.
Failure to observe this warning may result in an electric shock.
• Never operate the Digital Operator or other switches when your hand is wet.
Failure to observe this warning may result in an electric shock.
• Never touch the terminals while current is flowing, even if the VS-656DC5 stops.
Failure to observe this warning may result in an electric shock.
WARNING
• Never touch the radiation fins (heatsink) or input reactor since the temperature is very high.
Failure to observe this caution may result in harmful burns to the body.
• The VS-656DC5 is factory set to the suitable settings. Do not change the settings unnecessarily.
Failure to observe this caution may result in damage to the unit.
