1. The current supplied by the control panel shall
not be lower than the current absorbed by the
electric pumps, and depends also on the volt-
age drop due to the length of the cable.
2. Choose the current of the line protection de-
vice in relation to the maximum current ab-
sorbed by the motors.
3. Only if the electronic sensor is used.
4. For higher altitudes or other environmental
conditions not covered in this manual, please
contact your local After Sales / Service repre-
sentative.

Pump specifications

3.4
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
Technical data in Tab 1. The customer is respon-
sible for checking the limitations 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.

Electrical requirements

4.1
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
connection must correspond to the specifica-
tions 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:
See Figure 3
