Configuration Of The Integrated Inverter; Priming - DAB esybox mini3 Instructions Pour L'installation Et La Maintenance

Inverter with single-phase power supply
The thermal magnetic circuit breaker must be correctly sized (see Electrical Characteristics). For pumps not supplied with a plug, the
correspondence of the colours of the leads is as indicated in Table 3:

The appliance must be connected to a main switch that cuts off all the power supply poles. When the switch is in off position, the distance
separating each contact must respect the indications in Table 4.

3.2 Configuration of the Integrated Inverter

The system is configured by the manufacturer to satisfy most installation cases operating at constant pressure. The main parameters set in the
factory are:
• Set-Point (desired value of constant pressure)
• Reduction of pressure to restart
• Anti-cycling function:
However, these parameters and others can be set by the user according to the system. See par. 4-5 for the specifications.
For the definition of the parameters SP and RP, the pressure at which the system starts has the value:
Pstart = SP – RP For example: 2.7 – 0.3 = 2.4 bar in the default configuration
The system does not work if the utility is at a height higher than the equivalent in metres of water column of the Pstart (consider 1 bar = 10 m
water column): for the default configuration, if the utility is at a height of at least 27m the system does not start.

3.3 - Priming

The priming of a pump is the phase during which the machine attempts to fill the body and the suction pipe with water. If the operation is successful
the machine can work regularly.
