7.5 Installing the driver
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
• Install the driver in an enclosure whose pollution degree is 2 or above or protection
class is IP54 or better.
• Do not install any equipment that generates a large amount of heat or noise near the
driver.
• Do not install the driver underneath the controller or other equipment vulnerable to heat.
• Check ventilation if the ambient temperature of the driver exceeds 50 °C (122 °F).
• Be sure to install (position) the driver vertically.
