use the accessory tool (Fig.3_point 5) or a screwdriver. You must survey the
operation and close the loading door as soon as the water comes out (however
it is recommended to fit a check valve in the section of the suction pipe and to
use it to control the loading operation with the cap loose). Alternatively, in the
case where the suction pipe is intercepted by a closed valve, the loading op-
eration may be carried out in a similar way to the one described for installation
over head.

3 - COMMISSIONING

Maximum working pressure 8 bar.
The intake depth must not exceed 8m for e.sybox and 7 m for
e.sybox30/50.

3.1 - Electrical Connections

To improve immunity to the possible noise radiated towards other appli-
ances it is recommended to use a separate electrical duct to supply the
product.
Attention: always respect the safety regulations!
Electrical installation must be carried out by an expert, author-
ised electrician, who takes on all responsibility.
The system must be correctly and safely earthed as required by
the regulations in force.
The line voltage may change when the electropump is started.
The line voltage may undergo variations depending on other de-
vices connected to it and on the quality of the line.
The differential switch protecting the system must be correctly
sized and must be of the "Class A" type. The automatic differen-
tial switch must be marked with the following two symbols:
69
The thermal magnetic circuit breaker must be correctly sized
(see Electrical Characteristics)

3.2 Configuration of the Integrated Inverter

The system is configured by the manufacturer to satisfy the majority of
installation cases, that is:
operation at constant pressure;
•
Set-Point (desired value of constant pressure):
•
Reduction of pressure to restart:
•
Anti-cycling function:
•
However, all these parameters and many others can be set by the user.
There are many other operating modes and accessory functions. Thanks
to the different possible settings and the availability of configurable input
and output channels, it is possible to adapt the inverter operation to the
requirements of various systems. See par. 5-6-7
For the definition of the parameters SP and RP, the pressure at
which the system starts has the value:
Pstart = SP – RP
in the default configuration
The system does not work if the utility is at a height higher than the equiv-
alent 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.
SP = 3.0 bar
RP = 0.3 bar
Disabled
For example: 3.0 – 0.3 = 2.7 bar
