4. UNINSTALLATION AND OPEN ENCLOSURE OPERATIONS
After switching off the motor-inverter, the upper cover of the inverter can be opened by unscrewing the four
screws. After that, the necessary uninstallation or maintenance operations are possible.
WARNING - RISK OF ELECTRIC SHOCK: Do not perform any type of direct operation on internal parts
or open the cover of the inverter unless it is powered down. If in doubt, disconnect the power supply
to the motor-inverter using the control devices in the electrical panel and wait at least 60 seconds
before opening the cover.
All installation, de-installation or maintenance operations must be carried out in strict compliance
with the current laws on "safety at work": the indications given here are of a general nature and
cannot take into account the specific nature of each installation.
It is therefore recommended that the safety requirements applicable to the context in which
operations take place are strictly observed. If there is a conflict between the possibility of carrying
out any of the operations described herein and the work safety requirements (laid down by law or
by the person in charge of the premises where the operations take place), compliance with the safety
requirements must undoubtedly prevail.
5. COMMISSIONING AND CALIBRATION
Powering up is only permitted after closing the inverter cover and tightening the four fastening
screws.
Pay particular attention to the correct positioning of the gasket between the cover and the base of
the box before tightening the screws.
Commissioning operations may only be carried out by adequately trained personnel or personnel
with the necessary professional skills and/or qualifications to work on live systems and mechanical
moving parts.
The instructions in this paragraph lead to the rotation of the motor shaft and the corresponding
operation of the pump. It is therefore essential to check that the motor-inverter is connected to the
mechanical transmission (lantern pump connection) and is able to turn without causing damage to
the transmission components or creating situations of danger to people or animals.
