INSTALLATION

Warning!

The motor is designed exclusively for

operation with the supplied speed control

(frequency converter).

Direct on-line connection to the mains is not

possible for PM-motors.

Warning!

Risk of electric shock:

Motor terminals may still be live if the impeller

is rotating, even when the main incoming

supplied has been isolated.

Ensure the impeller is kept stationary before

opening and whilst the terminal box is open.

GENERAL

• Admissible environmental temperature: from -15 °C up to

+40 °C, with altitudes 1000 m above sea level

• Mounting: IM B3, B5

• Drive operating voltage: 400 VAC

• Insulation class: "F"; temperature rise to class B

(TEFC execution)

• IP55 degree of protection for the whole range

• Reduced dimensions

Speed controller and motor shall be installed by a qualified

electrician with adequate knowledge how to install speed-

controlled drive systems (frequency inverters) and EMC safety.

cable cross-sections and ambient temperature.

NOTE!

PARAMETERS

Speed controller parameters are set at the factory pro-

viding for optimal performance of fan and motor. This

includes motor parameters, ramp times, starting and

stopping methods and speed limitations.

Changing of these parameters may result in unstable

operation or motor won’t start. Original parameter values

can be downloaded from operation panel in case of

losing them.

MOTOR CABLE

Motor and speed controller is delivered with 3,5 m long motor

cable. If it should be replaced with longer one or disconnected

at the other end.

Following rules should be meet and considered:

• Motor cable should be shielded type.

• Shield should be grounded 360° at both ends of cable.

• Motor cable should be no longer than 20 meters.

• Motor is connected to star inside the motor.

• Phase wires are connected to terminals U1, V1, W1.

• Terminal connectors are not needed.

CONTROL CABLE

Control cable should be shielded. Keep control cable distance

min 200 mm from mains and motor cable.

CONTROL SIGNALS

Fan is started with potential free switch connected between

terminals 12 and 18. The circuit voltage is 24 VDC. AUTO-mode

should be selected from operation panel.

Speed reference can be given from with 0…10 V signal

connected in terminals 53(+) and 55(-). Alarm signal is availa-

ble in relay1 (terminals 01, 02 and 03).

Running indication is available in relay 2 (terminals 04, 05

and 06).

START UP AND FUNCTIONAL TESTING

After power up test check motor rotation:

Set speed controller to Hand on mode from operation panel.

Motor will start to the minimum or speed set in operation panel.

To change the direction of rotation:

• Remove power to the speed controller and wait for power to

discharge.

• Reverse the connection of any two of the three motor cables

on the motor or frequency converter side of the connection.

When direction of rotation is right set speed controller to Auto

on mode. Then speed controller will follow control signals.

SUPPLY CABLE

Mount mains supply to terminals L1, L2 and L3 and ground

wires to earth terminal and tighten.

Short circuit protection:

The speed controller must be protected against shortcircuit to

avoid electrical or fire hazard. The fuses mentioned below are

recommended to use to protect service personnel and equip-

ment in case of an internal failure in the speed controller. Speed

controller provides full short circuit protection in case of a short

circuit on the motor output.

Over current protection:

Provide overload protection to avoid fire hazard due to over-

heating of the cables in the installation. The speed controller

is equipped with an internal over-current protection that can

be used for upstream overload protection (UL-applications

excluded). See par. 4-18.

Current Limit. Moreover, fuses or circuit breakers can be used

to provide the over-current protection in the installation. Over-

current protection must always be carried out according to

national regulations.

Leakage Current (>3,5mA)

EN/IEC61800-5-1 (Power Drive System Product Standard)

requires special care if the leakage current exceeds 3,5 mA.

Earth grounding must be reinforced in one of the following

ways:

• Earth ground wire of at least 10 mm2

• Two separate earth ground wires both complying with the

dimensioning rules

Isolation switch

All speed controllers may be used with an isolated input source

as well as with ground reference power lines.

ALARMS AND WARNINGS

If alarm or warning messages appear, consult speed controller

operating manual in place fault messages and troubleshooting.

Protection and Features:

• Electronic thermal motor protection against overload.

• Temperature monitoring of the heat sink ensures that the

frequency converter trips in case of over temperature.

• The frequency converter is protected against short-

circuits between motor terminals U, V, W.

• If a motor phase is missing, the frequency converter trips

and issues an alarm.

• If a mains phase is missing, the frequency converter trips or

issues a warning (depending on the load).

• Monitoring of the intermediate circuit voltage ensures that

the frequency converter trips if the intermediate circuit voltage

is too low or too high.

• The frequency converter is protected against earth faults on

motor terminals U, V, W.

MAINTENANCE

Inspect the motor regularly and keep it clean. Especially impor-

tant is to keep the ventilation inlets clean.

If the motor protection is activated: The cause of the mal-

function must be investigated and corrected before starting the

motor again; motor failure, temporary overload or wrong set

values in the protection device.

BEARINGS

Most fans and motors are equipped with permanently lubricated

bearings. As a guideline the expected lifetimes is 40 000 h.

Type of bearing is to be found on the marking on the motor.

If there is a need for changing bearings contact FläktGroup

for instructions.

FREQUENCY CONVERTER

SAFETY INSTRUCTIONS

• Make sure the frequency converter is properly connected to

earth.

• Do not remove mains connections, motor connections or

other power connections while the frequency converter is

connected to power.

• Protect users against supply voltage.

• Protect the motor against overloading according to national

and local regulations.

• The earth leakage current exceeds 3.5 mA.

• The [OFF] key is not a safety switch. It does not disconnect

the frequency converter from mains.

Warning!

Speed controller tries to restart the motor after

alarm so the fan may start automatically.

Warning!

The voltage of the frequency converter is

dangerous whenever connected to mains.

Incorrect installation of the motor, frequency

converter or fieldbus may cause death,

serious personal injury or damage to the

equipment.

Consequently, the instructions in this manual,

as well as national and local rules and safety

regulations, must be complied with.

Warning!

Warning against Unintended Start.

1. The motor can be brought to a stop by means of digital

commands, bus commands, references or a local stop,

while the frequency converter is connected to mains.

If personal safety considerations make it necessary to

ensure that no unintended start occurs, these stop

functions are not sufficient.

2. While parameters are being changed, the motor may

start. Consequently, the stop key [STOP/RESET] must

always be activated; following which data can be modi-

fied.

3. A motor that has been stopped may start if faults occur

in the electronics of the frequency converter, or if a

temporary overload or a fault in the supply mains or

the motor connection ceases.

Warning!

Touching the electrical parts may be fatal

- even after the equipment has been discon-

nected from mains.

Also make sure that other voltage inputs have been discon-

nected, such as external 24 V DC, load sharing (linkage of

DC intermediate circuit), as well as the motor connection

for kinetic back up. Refer to the Operating Instructions for

further safety guidelines.

Warning!

The frequency converter DC link capacitors

remain charged after power has been discon-

nected. To avoid an electrical shock hazard, disconnect

the frequency converter from the mains before carrying

out maintenance. Wait at least as follows before doing

service on the frequency converter:

Voltage (V) Min. Waiting Time (Minutes)

4 15

200 - 240 1.1 - 3.7 kW 5.5 - 45 kW

380 - 480 1.1 - 7.5 kW 11 - 90 kW

Be aware that there may be high voltage on the DC link even

when the LEDs are turned off.
