8.3.8
Depending on the type of installation, limit the maximum length of the power cable as follows:
Panel model
ES 1 M
ES 3 M
8.3.9
Instrumental checks to be carried out by the installer:
a) continuity of the protection leads and of the main and supplementary equipotential circuits;
b) insulation resistance of the electric system;
c) test efficiency of the differential protection;
d) test the applied voltage;
e) test operation as indicated in point 8.5
8.4
Connection of the electro-probes
Use a lead with a section of 1.5 mm
Insert the rubber cap or the cable clamp in the electro-probe connecting lead.
Connect the lead to the electrode.
Electro-probes with a rubber ring: insert the electro-probe in the rubber cap previously inserted until the two lead
retaining screws are covered.
Electro-probes with cable clamp: screw the cable clamp onto the electro-probe, ensuring that it is firmly secured.
Make the connection to the panel by means of the terminals I, L and M as indicated on page 22
8.5
Connection to the control box (for submerged electropumps)
To connect the panel to the Control box supplied as standard on single-phase submerged electropumps, proceed as
follows:
A)
Remove the plug of the Control Box power cable.
B)
Connect the cable thus obtained to the terminals L1-N of
the yellow-green lead to the terminal
the blue lead to the terminal N
the brown lead to the terminal L1
C)
Connect the electropump to the Control Box following the wiring diagram and all the indications given above.
8.6
Starting the system
1. Connect the control BOX and the probe(s).
2. Ensure that the external control B is in OFF position (command excluded).
ATTENTION: if the remote control for connection to the terminals B is not used, the electropump is started
by turning on the main switch.
3. After having set the functions of ref., SP1-SP2-D1, close the inner door with the three screws.
4. Turn the magnetothermal switch ref. QM1 to position 0. Supply power to the panel by turning on the main switch
on the distribution panel. Turn on the isolating switch ref. QS1.
5. Press the button ref. SB1 in position MAN. The electropump is fed as long as it remains pressed.
6. Activate the remote control function B and check that the warning light ref. HL3 comes on to show that the
electropump is being fed.
Avoid starting the system, turning the isolating switch (ref. QS1) with the switch ref.
QM1 in position I.
8.7
Alarm system
Alarm intervention is indicated by the red light ref. HL2 and at the same time by a possible remote alarm which may be
connected to the terminals ref. Q.
Test the system after installation.
Against dry operation: in the event of alarm intervention, this will continue to work even after restoration of the level; to
rest the alarm, the power supply to the panel must be disconnected.
Starts control: the alarm system will intervene 5 times, then it will be stored in the memory. At this point the alarm
must be reset by disconnecting the power supply to the panel.
