4 Installation
This chapter explains the installation location and installation methods.
4.1 Installation location
The speed controller described in this manual has been designed and manufactured to be incorporated in general
industrial equipment.
Install it in a well-ventilated location that provides easy access for inspection.
The location must also satisfy the following conditions:
Indoors
Operating ambient temperature: 0 to +50 °C [+32 to 122 °F] (non-freezing)
Operating ambient humidity 85% or less (non-condensing)
Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid
Area not stored combustible materials
Area not exposed to direct sun
Area free of excessive amount of dust, iron particles or the like
Area not subject to splashing water (rain, 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 elds or vacuum
Altitude Up to 1000 m (3300 ft.) above sea level
4.2 Installing the speed controller
The speed controller is designed so that heat is dissipated via air convection.
Provide spaces so that the speed controller can be ventilated well through its top and bottom vent holes.
Installation direction
When installing the speed controller, provide a clearance of at least 25 mm (0.98 in.) in the vertical direction between the
speed controller and enclosure or other equipment within the enclosure.
When installing two or more speed controllers in parallel, it is possible to install them closely in the horizontal direction.
25 mm (0.98 in.)
or more
• Vertical direction
• Horizontal direction
