Installation Site
Install the power regenerative unit under the following conditions.
NOTICE: Do not install the power regenerative unit to an area greater than pollution degree 2 (UL standard).
Type
Enclosed wall-mounted
Open chassis
Protection covers are attached to the top and bottom of the power regenerative unit. Be sure to remove the protection covers before installing a 200
or 400 V Class power regenerative unit with an output of 30 kW or less in a panel.
To ensure proper performance and long operating life, follow the recommendations below when choosing a location for installing the RC5. Make
sure the power regenerative unit is protected from the following conditions:
• Extreme cold and heat.
Use only within ambient temperature range: -10°C to +40°C
• Rain, moisture. (For enclosed wall-mounted type)
• Oil sprays, splashes
• Salt spray.
• Direct sunlight. (Avoid using outdoors.)
• Corrosive gases or liquids.
• Dust or metallic particles in the air. (For enclosed wall-mounted type)
• Physical shock, vibration.
• Magnetic noise. (Example: welding machines, power devices, etc.)
• High humidity.
• Radioactive materials.
• Combustibles: thinners, solvents, etc.
Controlling the Ambient Temperature
To enhance the reliability of operation, the power regenerative unit should be installed in an environment free from extreme temperature increases. If
the power regenerative unit is installed in an enclosed environment, such as a box, use a cooling fan or air conditioner to maintain the internal air
temperature below 45°C.
Protecting the Power Regenerative Unit from Foreign Matter
Place a cover over the power regenerative unit during installation to shield it from metal power produced by drilling.
Always remove the cover from the power regenerative unit after completing installation. Otherwise, ventilation will be reduced, causing the power
regenerative unit to overheat.
