1.5 Place of installation

In rooms without weather exposure.

Avoid direct insolation.

Avoid dust.

Not in the neighborhood of strong electromagnetic fields.

Not in the neighborhood of inflammable material.

Provide for sufficient cooling. Install a fan if the frequency inverter is installed in a closed electrical
cabinet.

Altitude of installation: ≤ 4000 m, above 1000 m with reduced power (reduced output current).

Ingress protection rating of frequency inverter: IP20.

The frequency inverter produces noise. For this reason it should be installed in areas where people
normally don't stay.

Noise emission in operation is < 85 dB(A) in the case of sizes 1 through 7.

Noise emission in operation is approx. 86 dB(A) in the case of size 8. Ear protectors must be used when
staying near the frequency inverter

Use of the device in explosive atmospheres is not permitted.
1.6 Operation conditions

Size 1…7:
Ambient temperature: 0…55°C, as from 40°C, power reduction of 2.5% / K should be considered.

Size 8
Ambient temperature: -25…55°C, as from 45°C, power reduction of 2.5% / K should be considered.

Relative humidity: 5 ... 85%, no water condensation

Ambient pressure: 70 ... 106 kPa to be checked

The frequency inverter may be operated in TN, TT and IT grid types.

Operation in a corner-grounded TN grid shall not be permissible.

Environment specification: Pollution degree 2 and overvoltage category III (IEC 60664-1 /DIN VDE 0110-
1).

The frequency inverter may be connected to power supply every 60 s. If the unit is switched on more
frequently, it may be damaged. This must be considered when operating a mains contactor in jog
operation mode.

Max. permissible expected short circuit current at mains connection:

up to 132 kW device power (Size 7): 5 kA;

160…250 kW device power (size 8): 18 kA

as from 315 kW device power (size 8): 30 kA
