For protection against electric shock, do not
turn on the power supply until the wiring is
completed.

For the I/O signals cable, use a twisted pair cable.
y
Keep the wiring distance as short as possible [less than 2 m (6.6 ft.)] to
suppress the effect of noise.
y
A connection cable set is available as an accessory. Lead wires with a
connector allow for easy connection.

Connecting the power supply
Use a power supply that can supply the following current capacity.
When the power is turned on, the PWR/ALM LED will be lit in green.

* When the connector shape is of right angle,
in the model names indicates

.
y
When connecting, pay attention to the polarity of the power supply.
Reverse-polarity connection may cause damage to the driver.
y
Have the connector plugged in securely. Insecure connection may
cause malfunction or damage to the motor and driver.
y
When unplugging the connector, do so while spreading the latches
on the connector a little.
y
When cycling the power or plugging/unplugging the connector,
turn off the power and wait for the PWR/ALM LED to turn off.
y
Separate I/O signals cable at least 100 mm (3.94 in.) from
electromagnetic relays and other than inductance loads.
Additionally, route I/O signals cable perpendicular to power supply
cable and motor cable, rather than in a parallel fashion.
y
Do not route the power supply cable in the same conduits as other
power supply lines and motor cable.
y
If the motor cable or power supply cable generates an undesirable
amount of noise depending on the wiring or configuration, shield
the cable or install a ferrite core.
