DAB MCE-55/C V7.0 Instructions Pour L'installation Et La Maintenance page 36

2.1 Safety
The device contains an electronic device with inverter.
Use is allowed only if the electric system is in possession of safety precautions in accordance with the regulations in force in the
country where the product is installed (for Italy CEI 64/2). The appliance is not intended to be used by persons (including children)
with reduced physical, sensory or mental capacities, or who lack experience or knowledge, unless, through the mediation of a
person responsible for their safety, they have had the benefit of supervision or of instructions on the use of the appliance. Children
must be supervised to ensure that they do not play with the appliance.
2.2 Responsibility
The Manufacturer does not vouch for correct operation of the machine or for any damage that it may cause if it has been tampered
with, modified and/or run outside the recommended work range or in contrast with other indications given in this manual.
2.3 Particular warnings
Always switch off the mains power supply before working on the electrical or mechanical part of the system. Before
opening the equipment, wait at least 10 minutes after disconnecting it from the power supply. The capacitor of the
direct current intermediate circuit remains charged with dangerously high voltage even after the mains power has
been turned off. Only firmly cabled mains connections are admissible. The appliance must be earthed (IEC
536 class 1, NEC and other applicable standards).
Mains terminals and motor terminals may still have dangerous voltage when the motor is stopped.
3. APPLICATIONS
The inverter of the MCE/C series is a device conceived for the management of circulation pumps allowing integrated regulation of
the differential pressure (head); it is thus possible to adapt the performance of the circulation pump to the actual demands of the
system. This determines considerable energy saving, a greater possibility of control of the system, and reduced noise.
The MCE-55/C inverter is designed so that it can be housed directly on the pump motor body.
