DAB 4OL Serie Instructions Pour L'installation Et L'utilisation page 10

5.1 Selecting the electrical panel
Motors must be suitably protected against overloads and short circuits.
The following starting systems can be used: direct, impedance, autotransformer, soft-start.
Make sure the panel power ratings match those of the
pump. Incompatible combinations may cause faults and
fail to fully protect the motor.
Check the working limits specified in section 3.1.
5.2 Pump connections
Before connecting the motor to the pump, read this instructions manual and the one supplied with the pump or electric pump to which
the motor will be coupled. Keep both manuals with care. For further information, please contact our Sales and Service Department.
5.3 Installing the motor in a well or tank
Follow the instructions in the pump or electric pump manual.
When installing the electric pump vertically, make sure the motor does not rest on the bottom of the well or tank.
When installing the electric pump horizontally, make sure the motor does not rest on the bottom of the tank.
For further information, please contact our Sales and Service Department.
6. START-UP
Follow the instructions in the pump or electric pump manual.
6.1 Electrical connections to the electric pump
Electrical connections
may only be performed
by a qualified installer
in compliance
current regulations.
Single-phase version
•
Connect the electric pump to a supply line via a suitable electrical control panel containing the overload protection and the capacitor.
Refer to the wiring diagram on the outer casing of the motor and in figure 1 (page 12) and the documentation supplied with the electrical
panel. Refer to the motor rating plate for the capacity of the capacitor.
Install the electrical panel in a sheltered area.
Three-phase version
•
Connect the electric pump to a supply line via a suitable electrical control panel.
Install the electrical panel in a sheltered area.
Refer to the documentation supplied with the electrical
panel.
For connections to any external control devices (e.g.: pressure
switch, float) follow the instructions supplied with these devices.
7. MAINTENANCE, SERVICE AND SPARE PARTS
Before proceeding,
always make sure
the motor
disconnected from
the supply line.
The motor does not require any scheduled routine maintenance.
Users wishing to prepare a maintenance schedule should bear in mind that maintenance frequencies depend on the conditions of use.
For any requirements, please contact our Sales and Service Department.
7.1 Spare parts
Always specify the exact type of motor and code when
requesting our Sales and Assistance Service for
technical information or spare parts.
For further information, please contact our Sales and Service Department.
8. WARRANTY
Please refer to the sales contract for further information.
Make sure that the supply
voltage and frequency are
compatible with the electrical
with panel. The relative information is shown
on the motor rating plate and in the
documents supplied with the panel.
Provide suitable short circuit protection
on the supply line.
Maintenance operations may only be performed by
expert and qualified people. Use suitable equipment
is and protective devices. Observe all accident
prevention regulations. Do not attempt to disconnect the
connector from the motor head cable. This may only be done by
authorised personnel.
ENGLISH
Before installing, carefully read the instructions supplied
with the electrical panel.
For further information, please contact our Sales and
Service Department.
Before proceeding, make sure that all the connections
(even if they are potential-free) are voltage-free.
Unless otherwise specified in local bylaws, the supply
line must be fitted with:
a short circuit protection device;
−
a high sensitivity residual current circuit breaker (30mA) for
−
additional protection from electrocution in case of inefficient
grounding;
a general switch with a contact aperture of at least 3
−
millimetres.
Ground the system in compliance with current regulations.
Verify the correct execution of the junction, measuring
the insulation resistance. For a new motor the correct
measurement has to be at least 100 Mohm, and for a
motor/system in use, a value greater than 20 Mohm.
Only use spare parts to replace faulty components. Unsuitable
spare parts may cause the product to work incorrectly and cause
hazards for people and property.
