Page 16: Programming Guide
Cascade mode electrical connection Connect the supply cables to the motors and to the power supply following the instructions. The connection with the power supply must be made with installation of a tripolar circuit breaker (one for each frequency converter) with proper size and with a B-type differential switch. Cascade mode expansion board installation The cascade mode expansion board must be installed perpendicularly to the control board, checking that the connectors are properly connected, and that the board fits into the slides. -

- Page 22 Constant temperature operating mode. Constant temperature operating mode keeps constant the temperature at a point in the system. In this operating mode the frequency converter keeps constant the temperature. For this operating mode must be defined the type of system where the frequency converter will operate: Heating systems (Heat): in these systems an increase of the pump frequency will correspond to an increase of the temperature of the transducer.
