17.7 Inputs and outputs
17.7.1 Mains supply (L1, L2, L3)
17.7.2 Motor output (U, V, W)
1)
Output voltage in % of supply voltage.
2)
Depending on the pump family selected.
17.7.3 RS-485 GENIbus connection
The RS-485 circuit is functionally separated from other central
circuits and galvanically separated from the supply voltage
(PELV).
17.7.4 Digital inputs
All digital inputs are galvanically separated from the supply
voltage (PELV) and other high-voltage terminals.
17.7.5 Signal relays
1)
IEC 60947, parts 4 and 5.
The relay contacts are galvanically separated from other circuits
by reinforced insulation (PELV).
17.7.6 Analog inputs
1)
The factory setting is voltage signal "U".
All analog inputs are galvanically separated from the supply
voltage (PELV) and other high-voltage terminals.
17.7.7 Analog output
The analog output is galvanically separated from the supply
voltage (PELV) and other high-voltage terminals.
17.7.8 MCB 114 sensor input module
17.8 Sound pressure level
The sound pressure of the CUE is maximum 70 dB(A).
The sound pressure level of a motor controlled by a frequency
converter may be higher than that of a corresponding motor
which is not controlled by a frequency converter. See section
7.7 RFI filters.
