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.

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.
• 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 available 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 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 (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. Overcurrent 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 shortcircuits 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.
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.
• 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.
• 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.
INSTALLATION AT HIGH ALTITUDES
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.
Caution!
380 - 500 V, enclosure A, B and C:
At altitudes above 2 km, please contact FläktGroup
regarding PELV. 380 - 500 V, enclosure D, E and F:
At altitudes above 3 km, please contact FläktGroup
regarding PELV. 525 - 690 V: At altitudes above 2
km, please contact FläktGroup regarding PELV.

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 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.
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:
Voltage (V) Min. Waiting Time (Minutes)
415
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.

PARAMETER DESCRIPTION
If the settings are changed unintentionally reset the factory settings or
contact FläktGroup support.
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.
