50
Motor output (U, V, W)
1)
Output voltage in % of supply voltage.
RS-485 GENIbus connection
The RS-485 circuit is functionally separated from other
central circuits and galvanically separated from the
supply voltage (PELV).
Digital inputs
All digital inputs are galvanically separated from the
supply voltage (PELV) and other high-voltage
terminals.
Signal relays
1)
IEC 60947, parts 4 and 5.
The relay contacts are galvanically separated from
other circuits by reinforced insulation (PELV).
Analog input
1)
The factory setting is voltage signal "U".
All analog inputs are galvanically separated from the
supply voltage (PELV) and other high-voltage
terminals.
Sound pressure level
The sound pressure of the CU331SP is maximum 70
dB(A).
The sound pressure level of a motor controlled by a
Variable frequency drive may be higher than that of a
corresponding motor which is not controlled by a
variable frequency drive.
