FLÄKTGROUP PM-MOTOR WITH

INTEGRATED FC 106 FREQUENCY CONVERTER

INSTALLATION AND MAINTENANCE INSTRUCTIONS

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.

All cabling must comply with national and local regulations on cable

cross-sections and ambient temperature.

GENERAL

• Mounting: IM B3, B5

• Drive operating voltage: 400 VAC

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

(TEFC execution)

• IP54 degree of protection for the whole range

• Reduced dimensions

• Rare earth permanent magnets

INSTALLATION

ATTENTION!

Secure EMC connection.

Read manual for instructions.

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.

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

Running indication is available in relay 2 (terminals 04, 05 and 06).

SINGLE SPEED OPERATION:

Set constant speed reference (rpm) in parameter 411. Only external start

signal is needed.

MODBUS RTU:

Speed controller can be controlled via Modbus RTU. RS-485 cable is

connected to the terminals 68 (P), 69 (N) and 61 (COM). If speed controller

is last unit in line, it should be terminated by setting switch S801 in ON

position. Modbus operation is described in speed controller operation

instructions.

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.

OPERATING PANEL

The operating panel is accessory with integrated motor.

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 short-circuit to avoid

electrical or ﬁre hazard. The fuses mentioned below are recommended

to use to protect service personnel and equipment 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 overheating 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. 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 Stand-ard) 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 mm

• 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.

FREQUENCY CONVERTER

SAFETY REGULATIONS

1. The frequency converter must be disconnected from mains if repair

work is to be carried out.

Check that the mains supply has been disconnected and that the

necessary time has passed before works begins.

2. The [OFF/RESET] key on the LCP of the control unit does not

disconnect the equipment from mains and is thus not to be used as a

safety switch.

3. Correct protective earthing of the equipment must be established, the

user must be protected against supply voltage, and the motor must

be protected against overload in accordance with applicable national

and local regulations.

4. The earth leakage currents are higher than 3.5 mA.

5. Protection against motor overload is set by 1-90 Motor Thermal

Protection. If this function is desired, set 1-90 .

6. Do not break the connection to the motor or the electric grid while the

frequency converter is running.

Check that the mains supply has been disconnected and that the

necessary time has passed before work begins.

7. Please note that the frequency converter has more voltage inputs

than L1, L2 and L3, when load sharing (linking of DC intermediate

circuit) and external 24 V DC have been installed. Check that all

voltage inputs have been disconnected and that the necessary time

has passed before commencing repair work.

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.

• The speed controller is protected against short-circuits on motor

terminals U, V, W.

• If a mains phase is missing, the speed controller trips or issues

a warning (depending on the load).

• Monitoring of the intermediate circuit voltage ensures that the speed

controller trips if the intermediate circuit voltage is too low or too high.

• The speed controller is protected against earth faults on motor

terminals U, V, W.

MAINTENANCE

Inspect the motor regularly and keep it clean. Especially important is to

keep the ventilation inlets clean.

If the motor protection is activated: The cause of the malfunction 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.

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.

INSTALLATION AT HIGH ALTITUDES

Voltage (V)

Min. Waiting Time (Minutes)

415

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.

CAUTION!

At altitudes above 2 km, please contact

FläktGroup regarding PELV.

WARNING!

Touching the electrical parts may be fatal

- even after the equipment has been

disconnected from mains.

Also make sure that other voltage inputs have

been disconnected, 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

disconnected. 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:

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 [OFF/RESET] must always be activated;

following which data can be modiﬁed.

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.
