1.4 Operating Environment
This section describes the required environmental conditions and power supply conditions.
1.4.1 Environmental Conditions
The 6243/44 must be installed in an environment meeting the following conditions.
• Ambient temperature: 0C to +50C (temperature range for operation).
For the 6244, however, the temperature range for operation is 0ï‚°C to +40ï‚°C in the output range indi-
cated by the hatched sections shown in Figure 1-1.
• Relative humidity: 85% or lower (with no condensation)
• Location not subject to corrosive gasses
• Away from direct sunlight
• Dust free
• No vibrations
•No noise
The 6243/44 is designed with full consideration given to the noise contained in the AC power line.
Nevertheless, it is recommended that the 6243/44 be used in an environment with as little line noise
as possible.
If a location with line noise is unavoidable, use a noise filter.
• Positioning of the 6243/44
A cooling fan is located in the rear panel and vents are located in the side panels. Do not block the
fan and vents. Leave at least 10 cm of free space between the rear panel and the wall. Also, do not
position the 6243/44 in a position with the rear panel facing down.
Obstructing the vents will cause the internal temperature to rise, possibly causing faulty operation.
• Mounting in a rack
Ensure that the rack cannot topple over if the 6243/44 is off balance.
Ensure that the rack cannot topple over when the slide rail is pulled out.
Ensure that exhaust air from other 6243/44 is not directed at the vents on the side of the 6243/44.
To prevent the temperature in the rack from rising, install a heat sink fan.
