2.10 Conditions
48 YASKAWA SIEPC71061753C GA500 Technical Manual
2.10 Conditions
Obey the installation conditions specified in these instructions to take full advantage of the finless design of this
drive.
◆ 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 the specifications shown in Table
2.21.
Table 2.21 Installation Environment
Environment
Conditions
Area of Use
Indoors
Power Supply
Overvoltage Category III (IEC60664)
Surrounding Air
Temperature
-10 °C to +35 °C (14 °F to 95 °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.
• You can use finless-type drives at a maximum of +50 °C (122 °F) when you derate the output current.
*1
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 (IEC 60664-1)
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:
• When you install the drive at 2000 m (6562 ft) or lower
• When you install the drive between 2000 m to 4000 m (6562 ft to 13123 ft) and ground the neutral point on the power supply.
Contact Yaskawa or your nearest sales representative if you will not ground the neutral point.
Vibration

Installation Orientation
Install the drive vertically for sufficient airflow to cool the drive.
*1 Refer to Derating Depending on Ambient Temperature on page 54 for information.
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.
◆ Heatsink Plate Temperature
CAUTION! Burn Hazard. Do not touch a hot drive heatsink or external heatsink. Yaskawa recommends that you show a high
temperature warning mark or warning sign on the external heatsink. If you touch a hot drive heatsink plate or external heatsink,
it can burn you.
Keep the drive heatsink plate temperature lower than the maximum temperature even when the ambient
temperature is 50 °C (122 °F). Refer to Table 2.22 for the maximum temperature of the heatsink plate. When you
operate the drive in an ambient temperature of 35 °C (95 °F) or higher, refer to Derating Depending on Ambient
Temperature on page 54 and derate the drive.
