CB-110-4 3
1 Introduction
The VARIPACK frequency inverters (FI) have been de-
veloped for use in refrigeration, especially for capacity
control of BITZER compressors. In addition to speed
control, the VARIPACK frequency inverters can also
take over control functions of the refrigeration system.
These Operating Instructions describe the
BITZER VARIPACK frequency inverters for refrigera-
tion compressors. For further information on program-
ming the ModbusRTU interface, see
BEST SOFTWARE.
