The motor and driver are designed and manufactured for installation in equipment.
Install them in a well-ventilated location that provides easy access for inspection. The location
must also satisfy the following conditions:
• Inside an enclosure that is installed indoors (provide vent holes)
• Operating ambient temperature
• Operating ambient humidity 85%, maximum (no condensation)
• Area that is free from an explosive nature or toxic gas (such as sulfuric gas) or liquid
• Area not exposed to direct sun
• Area free of excessive amount dust, iron particles or the like
• Area not subject to splashing water (storms, water droplets), oil (oil droplets) or other liquids
• Area free of excessive salt
• Area not subject to continuous vibration or excessive shocks
• Area free of excessive electromagnetic noise (from welders, power machinery, etc.)
• Area free of radioactive materials, magnetic fields or vacuum
• 1000 m or lower above sea level

Installing the motor

How to install the motor
Install the motor onto an appropriate flat metal plate having excellent vibration resistance and
heat conductivity.
When installing the motor, secure it with four bolts (not supplied) through the four mounting
holes provided. Leave no gap between the motor and plate.
