7. ELECTRICAL CONNECTIONS AND ADJUSTMENT OF FLOATS
7.1 Choice of the electric control panel
Below are the indications for the choice of a control panel only for Fekafos 280 and 280 Double and Fekafos
550 Double models because for Fekabox models the pump is automatic.
The station must be adequately protected against overload and short-circuit.
Check the correct combination of electrical data between the control panel and the electropump.
An improper combination can cause problems and not guarantee the protection of the electric
motor.
Always refer to the electropump manual and to the instructions supplied with the electric panel.
The electrical connection must be made in accordance with the local safety regulations in force,
and exclusively by qualified personnel.
Commissioning
Before commissioning, read this instructions manual, that of the electropump and that of the
electric panel. Keep the manuals with care.
The commissioning operations must be performed exclusively by expert and qualified personnel,
in compliance with the regulations in force.
Always refer to the local and/or national regulations, laws and standards in force.
It is recommended to contact the Dab Assistance Service for the commissioning of the system.
For connecting the system it is recommended to use exclusively the panels ED, E-BOX indicated by the
manufacturer, supplied complete with detailed instructions for electrical connection and use.
7.2 Electrical connections
The pumps are provided with an earthed cable; ensure that the earth system is efficient. Before connecting the
system to the mains, ensure that the mains voltage is the same as the value indicated on the pump data plate and
that the earth connection can be made efficiently.
It is recommended to apply the pump data plate (supplied in the package in addition to the one already applied on
the pump by the manufacturer) on the tank, in a clearly visible position, or on the control box.
The connection must be made as follows:
Pump:
Pass the pump cable through the cable gland fitted on the tank, recognisable by the symbol
, tighten
the ring nut and connect the cable to the panel as indicated in the respective manual.
For Dab pumps and for any pump fitted with a cable having a section of 4G1.5 mm2 or larger, to ensure that the
passage and seal are guaranteed by the cable clamps, it is advisable to replace the grommet already fitted in the
clamps with the grommet supplied in the tank kit. For references to the details, figure 10 shows an example of the
replacement of the grommet on the Fekafos 280 tank.
