CAUTION
Correctly wire this product. Failure to observe this could result in motor runaway, etc.
Do not install a phase advancing capacitor, surge absorber or radio noise filter on the output side of the drive unit.
Correctly connect the output side (terminal U, V, W). The motor will not run properly if incorrectly connected.
Always install an AC reactor per each power supply unit.
Always install an appropriate breaker per each power supply unit. A breaker cannot be shared for multiple power
supply units.
Do not directly connect a commercial power supply to the motor. Failure to observe this could result in faults.
When using an inductive load such as relays, always connect a diode in parallel to the load as a noise
countermeasure.
When using a capacitive load such as a lamp, always connect a protective resistor serially to the load to suppress
rush currents.
Do not mistake the direction of the surge absorption diode to be installed on the DC relay for the control output
signal. If mistaken, the signal will not be output due to fault in the drive unit, and consequently the protective circuit,
such as emergency stop, could be disabled.
Do not connect or disconnect the cables between units while the power is ON.
Do not connect or disconnect the PCBs while the power is ON.
Do not pull the cables when connecting/disconnecting them.
Securely tighten the cable connector fixing screw or fixing mechanism. The motor could come off during operation
if insecurely fixed.
Always treat the shield cables indicated in the Connection Manual with grounding measures such as cable clamps.
Separate the signal wire from the drive line or power line when wiring.
Use wires and cables whose wire diameter, heat resistance level and bending capacity are compatible with the
system.
Ground the device according to the requirements of the country where the device is to be used.
Wire the heat radiating fins and wires so that they do not contact.
When using the RS-232C device as a peripheral device, caution must be paid for connector connection/
disconnection. Always use a double-OFF type AC power supply switch on the device side, and connect/disconnect
the connector with the AC power supply on the device side OFF.
