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 where the temperature does not increase or decrease quickly.
• When you install 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 or flammable materials.
• 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 4000 m (3281 ft to 13123 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 4000m (6562 ft to 13123 ft) and grounding the neutral point on the power supply.
Contact Yaskawa or your nearest sales representative if you will not ground the neutral point.

Installation Orientation Install the drive vertically for sufficient airflow to cool the drive.
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. Components near the drive can cause incorrect drive operation from
electrical interference.
NOTICE: Do not let unwanted objects, for example metal shavings or wire clippings, fall into the drive during drive installation.
Put a temporary cover over the drive during installation. Remove the temporary cover before start-up. Unwanted objects inside
of the drive can cause damage to the drive.
Note:
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. Components near the drive can cause incorrect drive operation from electrical interference.
