4. Operating conditions

(Standard execution)
The electrical panel functions correctly under the
following power and installation characteristics:
- Power fluctuation:
- Frequency fluctuations:
- Ambient temperature:
- Relative humidity: from 20% to 90% without
condensation
- Vibration: max 5,9 m/s
- Altitude: no higher than 1000 m, inside a closed
environment.
- Max liquid temperature:
• 50 °C EASYMAT 5MM, 9,2MM, 5MT, 9,2MT
• 40 °C EASYMAT 7,5MT
- Minimum delivery: 3 l/min
The current distributed by the frequency
converter must be equal to or lower than the
maximum current absorbed by the motor to
control.
5. Construction
(Standard execution)
