Feature
Specification
Line voltage
3-ph. 380 V … 480 V AC ± 10 %
The actual permissible line voltage depends on the installation altitude
Input frequency
47 Hz … 63 Hz
Modulation depth
87 % (the maximum output voltage is 87 % of the input voltage)
Power factor λ
0.95
Line impedance
≤ 1 % U
k
Starting current
Less than the input current
Pulse frequency (factory setting) 4 kHz
The pulse frequency can be increased up to 16 kHz in 2 kHz steps. A higher pulse
frequency reduces the permissible output current.
Electromagnetic compatibility
The devices are suitable for environmental classes C1 and C2 in conformance with
IEC61800-3. For details, see the Hardware Installation Manual, Appendix A2
Braking methods
DC braking, energy recovery (up to 100% of the output power)
Degree of protection
IP20
Operating temperature
● without power reduction
● with power reduction
LO operation
HO operation
LO/HO
0 °C … +40 °C (32 °F … 104 °F)
0 °C … +50 °C (32 °F … 122 °F)
up to 60° C (140° F), for details see the Hardware Installation
Manual
Storage temperature
-40 °C … +70 °C (-40 °F … 158 °F)
Relative humidity
< 95 % RH - condensation not permissible
Environmental requirements
Protected according to environmental class 3C2 to EN 60721-3-3 against damaging
chemical substances
Shock and vibration
Do not allow the inverter to fall and avoid it being subject to hard shocks. Do not install
the inverter in an area where it could be continuously subject to vibration.
Electromagnetic radiation
Do not install the inverter close to sources of electromagnetic radiation.
Installation altitude
● without power reduction
● with power reduction
Up to 1000 m (3300 ft) above sea level
up to 4000 m (13000 ft) above sea level, for details see the Hardware Installation
Manual.
Standards
UL, CE, SEMI F47
In order that the system is UL-compliant, UL-certified fuses, overload circuit-breakers
or intrinsically safe motor protection devices must be used.
