2.2 Installation Environment
The installation environment is important for the lifespan of the product and to make sure that the drive
performance is correct. Make sure that the installation environment agrees with these specifications.
Environment Conditions
Area of Use Indoors
Power Supply Overvoltage Category III
Ambient Temperature
Setting
Open chassis type (IP20): -10°C to +50 °C (14 °F to 122 °F)
Enclosed wall-mounted type (UL Type 1): -10 °C to +40 °C (14 °F to 104 °F)
• Drive reliability is better in environments that do not have wide temperature fluctuations.
• When installing the drive in an enclosure, use a cooling fan or air conditioner to keep the internal air
temperature in the permitted range.
• Do not let the drive freeze.
• To install the drive in areas with ambient temperatures ≤ 60 °C (140 °F), derate the output current and output
voltage.
Humidity
95% RH or less
Do not let condensation form on the drive.
Storage Temperature -20 °C to +70 °C (-4 °F to +158 °F) (short-term temperature during transportation)
Surrounding Area
Pollution degree 2 or less
Install the drive in an area without:
• Oil mist, corrosive or flammable gas, or dust
• Metal powder, oil, water, or other unwanted materials
• Radioactive materials or flammable materials, including wood
• Harmful gas or fluids
• Salt
• Direct sunlight
Keep wood and other flammable materials away from the drive.
Altitude
1000 m (3281 ft.) maximum
Note:
Derate the output current by 1% for each 100 m (328 ft.) to install the drive in altitudes between 1000 m to
3000 m (3281 ft. to 9843 ft.).
It is not necessary to derate the rated voltage in these conditions:
• Installing the drive at 2000 m (6562 ft.) or lower
• Installing the drive between 2000 m to 3000 m (6562 ft. to 9843 ft.) and grounding the neutral point on the
power supply.
Contact Yaskawa or your nearest sales representative when not grounding the neutral point.

Installation Position Install the drive vertically for sufficient cooling airflow.
NOTICE: Do not put drive peripheral devices, transformers, or other electronics near the drive. Shield the drive from electrical
interference if components must be near the drive. Failure to obey can cause incorrect operation.
NOTICE: Do not let unwanted objects, for example metal shavings or wire clippings, fall into the drive during drive installation
and project construction. Put a temporary cover over the top of the drive during installation. Remove the temporary cover before
start-up or the drive will overheat. Failure to obey can cause damage to the drive.
