• For UL standard (UL 508C), the product is recognized for the

condition of Maximum Surrounding Air Temperature 50 °C

(122 °F).

• Connect a Class 2 power supply (UL-certified) to the 24 VDC

power supply.

• The short-circuit testing has been conducted by UL with the

effective current value of 5000 A at 240 V.

• Installation conditions (EN Standard)

Driver is to be used as a component within other equipment.

Overvoltage category: II

Pollution degree: 2

Protection against electric shock: Class I

• For Low Voltage Directive

• The product is a type with machinery incorporated, so it should be

installed within an enclosure.

• This product cannot be used with cables normally used for IT

equipment.

• Install the product within the enclosure in order to avoid contact

with hands.

• Be sure to maintain a protective ground in case hands should make

contact with the product.

Be sure to connect the protective earth lead of the cable for motor

to the protective earth terminal on the driver, and ground the

driver’s protective earth terminal.

• To protect against electric shock using an earth leakage breaker

(RCD), connect a type B earth leakage breaker to the primary side

of the driver.

• When using a circuit breaker (MCCB), use a unit conforming to

the EN or IEC standard.

• Isolate the motor cable, power-supply cable and other drive cables

from the signal cables (CN1, CN4 to CN7) by means of double

insulation.

• EMC Directive

EMC of this product has been measured according to the

configuration illustrated in “Example of installation and wiring” the

USER MANUAL

. The compliance of the final machinery with the

EMC Directive will depend on such factors as the configuration,

wiring, layout and risk involved in the control-system equipment and

electrical parts. It therefore must be verified through EMC measures

by the customer of the machinery.

Name Regeneration resistor terminal (CN3) [RG1, RG3] Description When using the internal regeneration resistor, short the RG2 and RG3 terminals using a jumper wire supplied with the CN3 connector. If the optional regeneration unit (sold separately) is used, remove the jumper wire which has shorted the RG2 and RG3 terminals, and connect the lead wires to the RG1 and RG3 terminals. • Single-phase 100-115 VAC L, N: Connect single-phase 100-115 VAC.

• Before supplying power to the driver, turn all input signals to the driver to OFF. Otherwise, the motor may start suddenly and cause injury or damage to equipment. • When moving the motor output shaft by hand while the motor is at standstill, confirm first that the FREE input of the driver is turned ON. If the FREE input is not ON, an attempt to move the motor output shaft by hand may result in injury.

Installation direction Connection The driver is designed so that heat is dissipated via air convection and conduction through the enclosure. When two or more drivers are to be installed side by side, provide 20 mm (0.79 in.) and 50 mm (1.97 in.) clearances in the horizontal and vertical directions, respectively. When installing the driver in an enclosure, use two screws (three screws for NXD75-S) to secure the driver through the mounting holes. Screws (M4) are not supplied. Please provide separately.

Note • Installing or removing the battery must be performed by qualified personnel with expert knowledge of the handling of the driver and battery. • Remove the battery if the driver is not turned on for an extended period exceeding the data retention period. Failure to do so may cause the battery fluid to leak or battery performance to drop. • When installing or removing the battery, cut off the main power supply and 24 VDC power supply of the driver.
