WARNING !
HIGH LEAKAGE CURRENT: first connect to earth !
The rgf300 is a voltage regulator for three phase motors which operates
connected to the three phase mains voltage. The regulator must be installed by
qualified personnel who will connect the electric supply, attach the cables in
their permanent positions and commission the plant.
Incorrect installation of the rgf300 voltage regulator or the fan connected to it
may cause damage to objects or people so ensure the instructions in this manual
and all required security measures are read and followed carefully.
•
When receiving the goods, check that the packing is intact; in the event of any damage
due to transportation, notify the forwarding agent according to legal requirements.

animals and goods.
•
The purchaser must previously ascertain the suitability of the product for the use it is
intended for and assume all consequent risks and responsibility.
•
The rgf300 is a mains voltage regulator which uses the phase-cut principle completely
controlled over the three phases. It has been designed to vary the effective voltage on
three phase asynchronous motors for fans following a control signal (either mA, VDC or
Ohm). The appliance is manufactured for industrial use and therefore meets the EMC
standards that relate to industrial environments.
•
Using the appliance for purposes other than the ones described above will be considered
incorrect. In particular, the appliance may NOT be used to supply machine tools or any
other machines where the motor torque-speed characteristic is not quadratic.
•
If the equipment is intended for civil, commercial and/or light industrial use,
supplementary components and other types of equipment are required which can be
supplied on specific request from the purchaser. In this case, the purchaser must
provide a suitable design of the plant in which the appliance is to be installed (compliant
with EN 60555 - 2/3 standards regarding disturbance produced by electrical household
appliances and the like.
•
We decline all responsibility for any errors in the catalogues, publications or other
written documents. The information in this manual is not binding and we reserve the
right to make changes to the products without prior notice, at any time and in any way
that we deem convenient for production purposes or useful for increasing functionality
