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.

• The rgf series of products shown in this manual has been manufactured to the highest

standards.

• The manufacturer declines all responsibility for accident, loss or damage caused by the

use of these appliances. These must be correctly installed by qualified personnel in

conformity with their destined use and, whenever needed, must undergo correct

maintenance which should be carried out while ensuring the safety of people, domestic

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.

SAFETY RULES !

This appliance has been designed to give excellent performance provided it is installed and used carefully in

a suitable electric environment by qualified personnel.

The following rules must be obeyed when installing the regulator :

• Follow the instructions in this manual exactly and observe all safety measures in force.

• Do NOT tamper with or disassemble the regulator's internal components; doing so will

INVALIDATE THE GUARANTEE and may cause unnecessary damage.

• The regulator does not contain components that can be repaired by the user.

• The regulator must be suitably and effectively earthed by the installer according to the standards in force;

earthing is essential for the EMC filter to operate correctly.

• The user must be protected from the electric supply and the motor must be protected from possible

overloads in compliance with the standards in force.

• DO NOT supply the regulator without the internal protection panel made from lexan.

• DO NOT touch the electrical parts of the circuit when the power supply is connected under any

circumstances.

• Before supplying power to the unit, check carefully that the power and earth are correctly connected.

• If the mains supply is "disturbed", which may be due to other electrical power components causing

irregularities in the supply (power contactors), it is recommended that supplementary three phase

‘SURGE ARRESTER’filters are installed directly on the regulator supply.

• Avoid repeatedly connecting and disconnecting the power supply to the regulator; a constant supply

keeps the regulator at working temperature and eliminates problems caused by condensate inside the

protection case.

• Alternatively, use the remote terminal board contact 'MB' S2 = ON/OFF.

• The S2 = ON/OFF contact on the MB terminal board does not cut the mains supply and therefore cannot

be used as a safety switch.

• Install the regulator out of direct sunlight so that the container cannot get overheated and cause a

reduction in the maximum load current.

• The appliance may operate at environmental temperatures up to 50°C. Do not install it where this

temperature may be exceeded or the integrity of the regulator will be compromised and the appliance

may make the user appliance operate at full load (100%) with all consequent effects.

• The appliance must be stood vertically to encourage heat dissipation and to ensure there is a sufficient air

circulation and free space measuring 150 mm above and below the regulator. If several regulators are to

be grouped together on a single electric board, provide forced air circulation with a fan or cooling unit of

sufficient power.

• Use the holes on the lower and power terminal board sides of the appliance, for entrance of the

connection cables. This will prevent water, dust etc. from getting in and will ensure the IP55 protection

level is maintained using adequately sized cables and sheaths of suitable quality.

• Reassemble and check the cover of the external protection panel is properly closed.

• DO NOT alter or damage the identification stickers on the equipment.

• DO NOT force the trimmers to rotate beyond their set mechanical travel.

• Only alter the trimmers intended for regulation.

• Under no circumstances alter the trimmers marked with the spot of red paint.

1.0 PRESENTATION

THANK YOU for choosing an rgf300 series three phase voltage regulator, designed specifically to give the

maximum yield and greatest ease of use.

Like all our products, it has been built to the very highest quality standards using electronic components of

the utmost reliability which have undergone functional tests that guarantee use of the product for at least

30,000 hours of continuous operation without problem.

The rgf300 regulator is a power unit designed to meet requirements of quality and flexibility of use in plants

and machines in which proportional variation of the speed of rotation of the fans is essential.

The regulator is housed in a GEWISS GW Plast



120°C case (fig. 1) which guarantees high heat resistance

during ordinary use (120°C), increased mechanical impact resistance (IK = 08) and a protection level (IP55)

that allows the regulator to be installed out of doors.

Inside the case there is a lexan protection panel displaying instructions for use and commissioning of the

rgf300.

The 12A rgf300 is shown in fig. 1.

Like all our products, the rgf300 series bears CE marking as required by directive 89/336/ECC and its

subsequent modification EEC/92/31 on electromagnetic compatibility.

Since all these products are not used as "stand alone" appliances but incorporated into other plants or

machines, the standards' compatibility test was carried out under typical operating conditions.

The essential requirements of the directive are satisfied by conformity to "generic standards" for heavy

industry.

EN 50081-2 emission standard, EN 50082-2 immunity standard, and in particular:

EN 55011 class B, for radiated disturbances

EN 55011 class A, for conducted disturbances

ENV 50140 (IEC 801-3) for susceptibility (on the power supply)

ENV 50141 for conducted susceptibility on power lines

IEC 801-4 for fast transistors (bursts / high frequency disturbances)

IEC 801-2 for electrostatic discharge (ESD)

The tests and checks for conformity have been carried out according to the procedures described in the

product's technical documentation. The system used was formed by an rgf300 voltage regulator, a control

cable and relative controls, a power supply cable, a motor cable and a fan.

fig. 2

Responsibility for the final characteristics of the system or plant regarding the EMC directive

rests with the installer. The equipment must be installed in observance of the regulations in

force using the information presented in this manual.

1.2 INSTALLATION AND MECHANICAL DIMENSIONS

The rgf300 regulator must always be securely assembled and fixed using the four (4) attachment screws on

the side fins before connecting to the power supply.

The holes provided on the lower part of the regulator are for entry of the electric connection cables:

• four pole line (three phase + Earth) to power the regulator,

• four pole line (three phase + Earth) to power the load,

• signal cable lines for the analogue inputs and digital outputs.

To make installation simpler, all regulators are also fitted with stuffing boxes in PA6 polyamide, class V2,

IP68, for use with the power and signal cables.

The regulator is cooled by natural convection and so air must be able to pass freely below and above the

appliance.

Therefore ensure there is at least 150 mm. of free space above and below the regulator.
