Product Description

3.1

Product overview

The Q-SMART control panel is a single-phase elec-
tronic control panel intended to be used with 1 or 2
single-phase electric pumps for different fixed speed
applications.
It is suitable for pressurisation, emptying or sewage
systems. Check your type of installation and change
the parameters (see sections 5.4.3,
accordingly.

1. The current supplied by the control panel shall
not be lower than the current absorbed by the
electric pumps, and depends also on the volt-
age drop due to the length of the cable.
2. Choose the current of the line protection device
in relation to the maximum current absorbed by
the motors.
3. Only if the electronic sensor is used.
4. For higher altitudes or other environmental con-
ditions not covered in this manual, please con-
tact your local After Sales / Service representa-
tive.
