Installation direction
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.
