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

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.

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.
