Temperature
● Installation/Ambient temperature: –10°C to +50°C. When the
temperature ranges from –10°C to +40°C, no derating is
required. For temperature above 40°C, derate 1.5% for every
additional 1°C.
● Storage/Transportation temperature: ‑20°C to +60°C.
● For better reliability, use the AC drive in places without
sharp temperature changes.
● When installing the drive in an enclosed cabinet, use a
cooling fan or air conditioner to keep the incoming air
temperature below 50ºC. Failure to comply will result in
overheat or fire.
● Install the drive on the surface of an incombustible object
and leave sufficient surrounding space for heat dissipation.
● Take measures to prevent the drive from being frozen.
Humidity < 95% RH, without condensation
Environment
Pollution degree: 2 or below
Install the drive in a place that meets the following requirements:
● Free from direct sunlight, dust, corrosive gas, explosive and
inflammable gas, oil mist, vapor, water drop, and salty
element
● Insusceptible to vibration (away from equipment that may
generate strong vibration, such as a punch press)
● Free from unwanted objects such as metal powder, oil, and
water that may enter the drive
● Free from radioactive substances, combustible materials,
harmful gases and liquids, and salt corrosion
● Away from combustible materials such as wood
● Meeting Class 3C3 requirements in IEC 60721‑3‑3 in terms of
chemically active substances.
Altitude
● ≤ 1000 m: derating is not required
● > 1000 m: derate 1% for every additional 100 m
For 0.4 kW to 3 kW models, the maximum altitude is 2000 m; for
altitudes above 2000 m, contact Inovance. For models with the
power higher than 3 kW, the maximum altitude is 3000 m; for
altitudes above 3000 m, contact Inovance.
Vibration resistance
● For transportation in the package: compliant with class 2M3
in EN 60721‑3‑2
● For installation with the package removed: compliant with
ISTA 1H
1.2.2 Requirements on Installation Personnel
