Wiring
WARNING
Before wiring, installing, or removing this device, be sure to shut off the power supply.
Otherwise, there is a danger of electric shock.
CAUTION
Before handling the main unit and display unit or removing/inserting cables, touch a
grounded panel to discharge any static electricity.
If there is a risk of a power surge caused by lightning, use a surge absorber (surge protector).
Otherwise, there is a danger of fire or device failure.
Make sure that devices and equipment connected to this device have reinforced insulation or
double insulation suitable for their operating voltage and for this device's power.
Use this device with the provided power terminal block cover mounted. Otherwise, there is a
danger of electric shock.
Before touching terminals, shut off the power for the motor.
Attach ferrules with insulating sleeves to the wires for the MOTOR block. Do not use ferrules
without insulating sleeves. Use ferrules with insulating sleeves even when using a single wire.
Otherwise, there is a danger of electric shock.
Insert ferrules into the terminal block until the terminal part of the ferrule does not stick out.
Connect potentiometer (100 to 2500 Ω) wires to the terminals for motor feedback (terminals 4
to 6). If signal wires other than wires for the potentiometer are connected, the device may be
damaged. Make sure that the wiring is correct.

Noise suppression measures
Draw power from a single-phase instrument power supply and consider appropriate
measures so that noise does not adversely affect this device. If there is too much
electrical noise coming from the power supply, add an appropriate isolation
transformer and use an appropriate line filter.
