INSTALLATION
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.
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

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
2
• 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,
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.
