2.1 Choosing a Location
Be sure that the VFD is mounted in a location protected against the following conditions:
• Extreme cold and heat. Use only within the ambient temperature range:
-10°C to +60°C (+14°F to 140°F)*
• Direct sunlight (not for use outdoors)
• Rain, moisture
• High humidity
• Oil sprays, splashes
• Salt spray
• Dust or metallic particles in the air
• Corrosive gases (e.g. sulfurized gas or liquids)
• Radioactive substances
• Combustibles (e.g. thinner, solvents, etc.)
• Physical shock, vibration
• Magnetic noise (e.g. welding machines, power devices, etc.)
* 2 kHz carrier frequency
WARNING
• When preparing to mount the IMPULSE
®
•G+ & VG+ Series 4 VFD, lift it by its base. Never lift the VFD by
the front cover, as doing so may cause damage or personal injury.
• Mount the VFD on nonflammable material.
•The IMPULSE
®
•G+ & VG+ Series 4 VFD generates heat. For the most effective cooling possible, mount it
vertically. For more details, refer to the “IMPULSE
®
•G+ & VG+ Series 4 Dimensions/Heat Loss-Open
Chassis” in this chapter.
• When mounting units in an enclosure, install a fan or other cooling device to keep the enclosure
temperature below 65°C (149°F)*.
Failure to observe these warnings may result in equipment damage.
