Electrical System - Presto CONTI COMPACT CC-20 V Operating Manual

Constructive description
5.4. Electrical system
A three‐phase power supply (400 V, 50 Hz)
is required on site for installing the
machine. The specific connection values
can be found in the chapter "Technical
data".
The "Electric System" module controls the
machine and supplies it with electric
energy. The processing time of the plant
and/or the bale length may be selected
freely within pre‐set limits. Further
information can be found in chapter 6
"Operation".

The built‐in motor circuit breaker protects
the electrical system and switches off
when overloaded. The setting (H=Manual)
of the motor circuit breaker must not be
changed. If the motor circuit breaker has
tripped, it can be reset after a short time
using the "RESET" key (20). The machine is
then ready to operate again.
