All the above limits, temperatures and speeds, are secured by parameters in the drive and
application controller softwares.
Installation and servicing of the compressor by qualified personnel only. Follow these instructions and sound refrigeration engineering
practice relating to installation, commissioning, maintenance and service.
The compressor must only be
used for its designed purpose(s)
and within its scope of application
(refer to «operating limits»). Consult
Application guidelines and datasheet
available from cc.danfoss.com
- Depending on the frequency converter
version, the physical position of individual
connectors may differ from below diagram.
- Always make sure that the compressor
terminals T1, T2, T3 are connected to the
frequency converter terminals 96, 97, 98
respectively.
