Ref.
Automatic magnetothermal switch, for protection of the P1 motor supply line against overloads and short
QM1
circuits, with manual reset.
QS1
Supply line insulating switch.
SB1
Button for manual operation of the electropump as long as it is pressed.
Manual regulation of the minutes scale for setting the pause time from 3 to 12 minutes after intervention of the
D1
protection against dry operation (on the M2S module).
SP1
Microswitch (on the M2S module) for manual setting of the following functions:
Switch "1": forced stopping of the electropump if an excessive number of starts
is requested. MAX one start per minute.
Switch "2": setting of system operation according to the number of electro-
probes that are to be used.
Switch "3": setting for draining or filling operation (possible only with the
support of two probes).
SP2
Microswitch (on the M2S module) for manual setting of the electro-probes for draining or filling.
Switch "1": when this switch is turned ON the electro-probes are set for
draining operation. ATTENTION: the switch "2" must NOT be ON.
Switch "2": when this switch is turned ON the electro-probes are set for filling
operation. ATTENTION: the switch "1" must NOT be ON.
HL2
Red warning light indicating protection against dry running or excessive starts.
HL3
Green warning light indicating that the electropump is being fed.
Control B does not require connection to
safety circuit (CEI EN 60204-1).
Connection terminals for the remote alarm for indicating intervention of the protection against dry running or
Q
excessive starts.
31 - 32
Contact characteristics: without potential, NO (normally open);  5 Amp; 250V.
B
Connection terminals 24 a.c. for the pressure switch, water level control float or other remote control to be
connected, removing the jumper. Maximum resistance allowed for the control circuits  5 K.
3 - 4
I
Connection terminal 24V a.c. for the common electro-probe to be used in systems where the water is not in
direct contact with the earth system (Maximum resistance of electro-probe less than or equal to 80 Kohm).
18
L
Connection terminals 24V a.c. for the electro-probe that controls the maximum level or dry operation
depending on the setting as in ref. SP1 (Maximum resistance of electro-probe less than or equal to 80 Kohm).
19
M
Connection terminal 24V a.c. for the maximum level control electro-probe. (Maximum resistance of electro-
probe less than or equal to 80 Kohm).

L1-N
Connection terminals of the submerged electropumps with control BOX
Scrupulously respect the required correspondence.
8.3 Electrical connections
8.3.1 Before connecting the power cables to line input terminals L1-N, ensure that the main switch on the power
distribution panel is in OFF position (O), and that no one can switch on the power accidentally.
8.3.2 Scrupulously observe all the regulations in force concerning safety and accident prevention.
8.3.3
Ensure that all the terminals are fully tightened, paying particular attention to the earth terminal.
8.3.4 Connect the cables to the terminal board as indicated in the wiring diagrams given in this booklet.
8.3.5 Check that all the connecting cables are in excellent condition, with the external sheathing unbroken.
8.3.6
Check that the differential switch that protects the system is of the right size.
Provide automatic protection of the supply line against short circuits by means
of the Curve C 16A Automatic Switch for panel type ES 1 M and 20 A for panel
type ES 3 M.
8.3.7 The system must be correctly and safely earthed as required by the regulations
in force.
