8.9 Operation with inverter/converter: the use of this electronic equipment as control and regulation unit, must be studied very carefully
in order to verify that it doesn't produce electromagnetic interferences or induced currents which can reduce the safety standard
required by the ATEX norms in reference to the zone in which the equipments are working.
In any case, the following conditions must be respected:
- it is compulsory to use the inverter Danfoss VLT FC202 (ex VLT8000) serie or more recent models with better performances;
use of models corresponding to other brands must be authorized by Caprari S.p.A.;
- it is compulsory to set the inner commutation frequency of the inverter at maximum 4kHz or at the minimum frequency admitted
by the inverter;
- it is compulsory to equip the inverter with the correct battery of filters, between inverter and the motor, for the reduction
of [dv/dt];
- it is compulsory to use the inverter only in the modulation range 35 - 60 Hz.
8.10 The standard maximum ambient temperature is 40°C. A maximum ambient temperature of 60°C can be accepted on request and
following tests by Caprari S.p.A. This temperature will be indicated on the rating plate of the electric pump.
