Installation Environment
Installation Environment
Use and store the Power Controller within the rated ambient temperature and
humidity ranges. If more them one Power Controller is installed side-by-side
or vertically, the heat that is generated will cause the internal temperatures of
the Power Controllers to rise and will shorten their service life. In these kinds
of installations, take suitable measures, such as installing fans for forced cool-
ing.
The Power Controller is designed for indoor use only. Also, do not use the
Power Controller in the following environments.
• Locations subject to water or oil
• Locations subject to direct sunlight
• Locations where dust or corrosive gases (in particular, sulfuric or ammo-
nia gas) are present
• Locations where flammable or explosive gases are present
• Locations subject to extreme temperature changes
• Locations where icing or condensation may occur
• Locations subject to excessive shocks or vibration
• Locations subject to direct heat radiated from heating devices.
Take appropriate and sufficient countermeasures when installing systems in
the following locations:
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
Installation Location
When installing in a control panel, consider the ease of operation, ease of
maintenance, and environmental factors.
!WARNING
Leave at least 100 mm of space above and below the Power Controller when
installing it to allow heat to dissipate. Do not obstruct the area around the
Power Controller and especially the area around the heat sink.
Ambient Temperature
The ambient operating temperature range is
−
15 to 55
°
C, but take the follow-
ing considerations into account. When the ambient temperature exceeds
40
°
C, reduce the maximum load current as shown below.
