CB-110-4 5
3 Technical data
VARIPACK frequency inverter
Operating voltage 380 .. 480 V +/- 10% (TN and TT mains supply), 50 ... 60 Hz +/- 5%
Operation on IT networks possible for F.U (IP20) and F.Y (IP66). To obtain compatibility
with this network configuration and the network monitoring installed there, the integrated
EMC filters must be deactivated and special external filters must be used.
Operation on generators, emergency power units and networks equipped with power
factor correction units only after consultation with BITZER.
Leakage current < 20mA
Permitted phase
asymmetry
maximum 3%
Enclosure class Enclosure rating - IP20, IP55 or IP66 (NEMA 4X)
Overvoltage categoryIII
Storage -40°C .. +60°C
Place of installation • Permitted ambient temperature: -10°C .. +50°C. From 40°C ambient temperature on-
wards, continuous output current capacity of 1.5% per degree Celsius for IP55 and
2.5% for IP66 (derating). FI size FPU+90: > 35°C: Derating: 1,1% per °C. The selection
in the BITZER SOFTWARE can take this directly into account.
• Permitted relative humidity: max. 95%, non-condensing.
• F.W (IP55) and F.Y (IP66) are designed to operate in 3S3/3C3 environments in ac-
cordance with IEC 60721-3-3. F.U (IP20) are designed to operate in 3S2/3C2 environ-
ments in accordance with IEC 60721-3-3.
• Maximum permitted altitude abovesea level: 4000m. From 1000m above sea level
onwards, capacity reduction by 1% per 100 m (derating). The selection in the
BITZER SOFTWARE can take this directly into account.
• IP20: Pollution degree 1, non-flammable, non-corrosive.
IP55: Pollution degree 2, non-flammable, non-corrosive.
IP66: Pollution degree 4, non-flammable, non-corrosive.
Vibrations / oscilla-
tions
Test according to EN 60068-2-6 (Fc), 10 cycles per axis on each of three mutually per-
pendicular axes:
• 10Hz<f<57Hz sinusoidal amplitude 0.075mm.
• 57Hz<f<150Hz sinusoidal 1g.
Safe Torque Off
(STO)
Safe Torque Off is a safety function for the electrical power drive, Safe Torque Off (STO).
EMC The compressor with frequency inverter (FI) meets the EU EMC directive 2014/30/EU,
see chapter Electromagnetic compatibility (EMC), page 20.
The selection and assignment of the VARIPACK fre-
quency inverters to the BITZER reciprocating com-
pressors is done by means of the BITZER SOFTWARE
using the ACCESSORIES button.
