INSTALLATION AND INSTRUCTIONS
1.2 Installation of the converter unit
Install the converter unit on a strong surface securely with bolts.
Leave enough clearances and take cooling measures.
Avoid places where the converter unit is subjected to direct sunlight, high temperature and high humidity.
Install the converter unit on a nonflammable surface.
When encasing multiple converter units, install them in parallel as a cooling measure.
For heat dissipation and maintenance, keep clearance between the converter unit and the other devices or enclosure surface. The
clearance below the converter unit is required as a wiring space, and the clearance above the converter unit is required as a heat
dissipation space.
*1
For replacing the cooling fan 30cm of space is necessary in front of the converter unit. Refer to the FR-CC2 Instruction Manual for fan replacement.
1.3 Environment
Before installation, check that the environment meets following specifications:
Surrounding air

temperature
Ambient humidity
Storage temperature
Atmosphere
Altitude
Vibration
*2
Temperature applicable for a short time, e.g. in transit.
*3
For the installation at an altitude above 1,000m up to 2,500 m, derate the rated current 3 % per 500 m.
*4
Surrounding air temperature is a temperature measured at a measurement position in an enclosure. Ambient temperature is a
temperature outside an enclosure.
