3.4 Pump specifications

Refer to the user and maintenance manual of the
electric pump. It is essential to consider the limita-
tions of use of the control panel together with those
of the electric pump. See the
1. The customer is responsible for checking the limi-
tations of the electric pump if they are not specified
in this manual.
4 Installation
Precaution
WARNING:

Observe the accident prevention
regulations in force.

Use suitable equipment and protec-
tive devices.

Always refer to the local regula-
tions, legislation and codes in force
regarding the selection of the instal-
lation site, plumbing and power
connection.

4.1 Electrical requirements

The local regulations in force overrule the specific
requirements given below.
Electrical connection checklist
Check that the following requirements are met:

The electrical leads are protected against high
temperature, vibrations and collisions.

The current type and voltage of the mains con-
nection must correspond to the specifications on
the data plate on the pump.

It is recommended to provide electrical power to
the control panel with a dedicated power line
equipped with:
o
A high-sensitivity differential switch (30
mA) [residual current device RCD].
o
A mains isolator switch with a contact gap
of at least 3 mm.
Control panel checklist
NOTICE:
The control panel must be compatible with the
data of the electric pump powered by the same
panel. It is essential to consider the limitations of
use of the control panel together with those of the
electric pump. Inappropriate combinations do not
guarantee the functionality and protection of the
electric pump and control panel.
Check that the following requirements are met:

The control panel must protect the pumps
against short circuits. A time lag fuse or a circuit
breaker (Type C model is suggested) can be
used to protect the control panel.
Technical data in Tab

A time lag fuse which is inside the control panel
protects the pump against short circuits. A 12A
gG fuse for the pumps is provided (F1, F2). Re-
fer to Figure 7.

The control panel must be programmed correct-
ly. Refer to the "Start-up and
tion (sections 5.4.3, 5.4.4)
Motor checklist
Use a 3-wire power cable (2 + earth/ground). All
cables must be heat-resistant up to a minimum of
+70°C (158 °F).

4.2 Mechanical installation

NOTICE:

Incorrect mechanical installation can cause
the control panel to malfunction and break.

Read this manual and the manual for the
electric pump before installation.
Ensure that the following conditions are met:

Refer to figure 4 for proper mounting of the con-
trol panel.

Do not install the control panel in an area ex-
posed to direct sunlight and/or near heat
sources. Refer to the ambient temperature
range in the Technical data

Install the control panel and the electric pump in
a dry, frost-free site, observing the limitations of
use and ensuring the motor is sufficiently
cooled.

Do not use the product in explosive atmos-
pheres or in the presence of corrosive and/or
flammable dust, acid, or gas.

4.3 Electrical installation

Precaution
WARNING:

Make sure that all connections are
executed by a qualified installer and
in compliance with the regulations
in force.

Before running the unit (control
panel and electric pump), make
sure that the unit and the control
panel are isolated from the power
supply and cannot be energised.
Grounding (earthing)
Electrical hazard

Always connect the external protec-
tion conductor to the ground (earth)
terminal before making other elec-
trical connections.
