SAFETY PRECAUTIONS

DANGER: The voltages present in the supply cables, the output cables and terminals, the control
power supply wiring and in certain internal parts of causing severe electric shock and
may be lethal !

WARNING: Whenever the drive has been energised; it must be isolated before work may continue.
A period of five minutes must elapse after isolation to allow the internal capacitors to
discharge fully. Until the discharge period has passed dangerous voltages may be
present within the drive.

Persons supervising and performing electrical installation must be suitably qualified and
competent in these duties, and should be given the opportunity to study this manual before work is
started.

4. Mechanical installation

4.1. Location

The installation must be located in a place free from dust; corrosive vapours; gases and all liquids.
Care must also be taken to avoid condensation of vaporised liquids, including atmospheric moisture.

4.2. IP rating

IP 20 or IP 00 (e.g. location in a switchboard ) or IP 54

4.3. Mounting

• The unit must be mounted vertically, and sufficient clearance must be allowed around the unit to
allow adequate flow of cooling air over the fins of the heat sink. A minimum of 50 mm is required
above and below the unit, and some clear space should also be allowed at the sides and front.

• Location within the cubicle (e.g. switchboard) without any ventilation of the air inside :

Heat can escape only by conduction through the skin of the cubicle, which is cooled by radiation to

the external air.

A minimum distance from the enclosure boundaries : 50 mm
Heat dissipation power : approx. 4% of the real output power.

5. Electrical installation

SAFETY PRECAUTIONS
DANGER: The voltages present in the supply cables, the output cables and terminals, the control
power supply wiring and in certain internal parts of the drive are capable of causing
severe electric shock and may be lethal !

WARNING: Whenever the drive has been energised; it must be isolated before work may continue.
A period of five minutes must elapse after isolation to allow the internal capacitors to
discharge fully. Until the discharge period has passed dangerous voltages may be
present within the drive.

Persons supervising and performing electrical installation must be suitably qualified and
competent in these duties, and should be given the opportunity to study this manual before work is
started.

5.1. Power connections

CHECK THAT

• the unit is disconnected from the input power before making connections to the terminals

- AC input power circuit breaker, installed upstream on the low voltage switchboard, is in "off"
position

5.1.1. Connection procedure

• FOR PROTECTION OF LIFE AND PROPERTY, EARTH WIRES SHOULD ALWAYS BE
CONNECTED FIRST !

• remove the front panel that is secured with screws

• connection cables should enter at the bottom

• connect the 1 PHASE mains supply to the terminals N; L.

• connect the motor terminals to the U, V, W terminals of the drive

• refit the front panel

Never connect the input power to the U, V, W terminals of the drive !!!

5.1.2. Recommended protection devices installed upstream of the drive and cabling

Drive model FIA-L 18 37 55 75 110 150 220 250

fuse ratings* 6A 10A 16A 20A 25A
cable size (for 3-core)** mm2 1,5 2,5 4,0

* The use of slow protection devices (curve C) is recommended because a current surge may appear at power on.

**Cable sizes are recommendations only. Cabling should conform to local codes of practice and regulations.

5.1.3. Motor connection

• No protection devices between the drive and the motor are recommended. The power connections
from the drive output to the motor may be switched, for isolation purposes; but not for control
purposes.

• Connection between the drive and the motor as short as possible are recommended to prevent
emissions from the motor cable.

If it is not possible, screened or armoured cable may be used . The screen or armour should be

connected in the same way as for standard cable (to both the motor earth terminal and the drive
earth terminal).

• Installations with long cable runs to the motor (i.e. above approx. 30 m), may need the addition of
motor line chokes to prevent nuisance tripping of the drive caused by capacitative leakage effects.

Output voltage of the drive FRECON FIA - L : 3 x 230 V !

MOTOR WINDING CONNECTION MUST BE COMPATIBLE WITH THIS VOLTAGE !

IN THE MOST CASES : DELTA CONNECTION

5.2. Motor speed

• Standard squirrel-cage ac induction motors are designed as single speed machines. If it is intended
to use the capability of the drive to run the motor at speeds above its designed maximum, it is
strongly recommended that the motor manufacturer is consulted first.

• The principal risks due to overspeeding are the destruction of the rotor by centrifugal force, or of the
bearings by vibration or heat.

• Low speed is liable to result in overheating of the motor because the effectiveness of the internal
cooling fan reduces in proportion to the square of the reduction of speed. Motors should be
equipped with thermistor protection, and if full benefit of the use of low speeds is to be gained from
a variable speed drive it may be necessary to arrange additional cooling for the motor.

5.3. Control connections

5.3.1. Connection procedure

• remove the front panel that is secured with screws.

• for control connections use cable of 0,5 mm

NOTE: Connections must be made with the short length of screened cables. If these cables are

altered in any way the filter will operate, but compliance with any emission standard is
no longer assured.

Input cable into the filter (filtered cable) and no control circuit should be run parallel to an unscreened
motor cable or unfiltered supply cable with a spacing less than 0,3 m and over a distance exceeding 1m.
