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 be-

tween 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. Original parameter values can

be downloaded from operation panel in case of losing them.

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.

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 instruc-

tions.

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 frequency converter 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 over-load 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.

RESET OF ORIGINAL PARAMETERS

• Go to parameter 0-50 LPC Copy

• Set parameter value to 2 (All from LCP)

• Wait that copy is completed

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,

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.
