2.2 Installation Environment
The installation environment is important for the lifespan of the product and to make sure that the bypass performance
is correct. Make sure that the installation environment agrees with these specifications.
Environment
Conditions
Area of Use
Indoors
Ambient Temperature Setting
IP20/UL Type 1: -10 °C to +40 °C (14 °F to 104 °F)
• Do not let the bypass freeze.
Humidity
98% RH or less
Do not let condensation form on the bypass.
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 bypass 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 bypass.
Altitude
1000 m (3281 ft) maximum
Note:
Derate the output current by 1% for each 100 m (328 ft) to install the bypass 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 bypass at 2000 m (6562 ft) or lower
• When you install the bypass between 2000 m to 4000 m (6562 ft to 13123 ft) and ground the neutral point on the power supply.

)
Installation Orientation
Install the bypass vertically for sufficient cooling airflow.
NOTICE: Do not let unwanted objects, for example metal shavings or wire clippings, fall into the bypass during installation. Put a
temporary cover over the bypass during installation. Remove the temporary cover before start-up. Unwanted objects inside of the
bypass can cause damage to the bypass.
Note:
Do not put peripheral devices, transformers, or other electronics near the bypass. Shield the bypass from electrical interference if components
must be near the bypass. The bypass or the devices around the bypass may malfunction due to electrical interference.
