1. INTRODUCTION
EC motor contains permanent magnet motor and integrated
speed controller which is called commutation unit. Speed can be
controlled with a 0-10V DC signal or Modbus RTU. Main voltage
requirement is 1-phase 230 VAC or 3-phase 400 VAC depending
on motor type.
Motors have 1 meter long supply and control cables or terminal
box depending on motor type. See Chapter 5.5 Connection dia
-
grams.
EC-motor is ready to be used. All parameters are set. Only power
from mains and control signals are needed.
2. SAFETY REGULATIONS AND INFORMATION
Read these operating instructions carefully before starting work
on the device. Observe the following warnings to prevent malfunc
-
tions or danger to persons.
These operating instructions are to be regarded as part of the de
vice. The device is only to be sold or passed on together with the
operating instructions.
These operating instructions may be duplicated and distributed to
inform about potential dangers and their prevention.
2 1. HAZARD LEVELS FOR WARNINGS
These operating instructions use the following hazard levels to
indicate potentially hazardous situations and important safety
regulations:
DANGER
Indicates an imminently hazardous situation which
will result in death or serious injury if the specified
actions are not taken. Compliance with the instruc
-
tions is imperative.
WARNING
ndicates a potentially hazardous situation which can result in
death or serious injury if the specified actions are not taken. Exer
-
cise extreme caution while working.
CAUTION
Indicates a potentially hazardous situation which can result in minor or moderate injury or damage to property if the specified actions are not taken.
NOTE. A potentially harmful situation can occur and, if not avoided, can
lead to property damage.
2.2 STAFF QUALIFICATIONS
The device may only be transported, unpacked, installed, operated, maintained and otherwise used by suitably qualified, trained
and authorized technical staff.
Only authorized specialists are permitted to install the device, to
carry out a test run and to perform work on the electrical instal
-
lation.
2.3 BASIC SAFETY RULES
The safety hazards associated with the device must be assessed
again following installation in the final product. Note the following
when working on the device:
Do not perform any modifications, additions or conversions on the
device without the approval of FläktGroup Oy.
2.4 VOLTAGE
Check the device’s electrical equipment at regular intervals; see
Chapter 6.2 Safety inspection.
Replace loose connections and defective cables immediately.
DANGER
Electrically charged device Risk of electric shock
• When working on an electrically charged device,
stand on a rubber mat.
WARNING
Live terminals and connections even with device switched off
Electric shock
• Wait five minutes after disconnecting the voltage at all poles
before opening the device.
CAUTION
In the event of a fault, the rotor and the impeller will be energized
The rotor and the impeller have basic insulation.
• Do not touch the rotor and impeller once installed.
CAUTION
If control voltage or a stored speed set value is applied, the motor
will restart automatically, e.g. after a power failure.
Risk of injury
• Keep out of the device danger zone.
• When working on the device, switch off the line voltage and en
-
sure that it cannot be switched back on.
• After working on the device, remove any tools or other objects
from the device.

CAUTION
The motor restarts automatically when operating voltage is applied, e.g. after a power failure.
Risk of injury
• Keep out of the motor’s danger zone.
• When working on the motor, switch off the line voltage and en
-
sure that it cannot be switched back on.
• Wait until the motor comes to a stop.
2.5 ELECTROMAGNETIC RADIATION
Interference from electromagnetic radiation is possible, e.g. in
conjunction with open-and closed-loop control devices. If imper
missible radiation levels occur following installation, appropriate
shielding measures have to be taken by the user.
NOTE Electrical or electromagnetic interference after installing the
device in customer equipment.
• Verify that the entire setup is EMC-compliant.
2.6 MECHANICAL MOVEMENT
DANGER
Ejected parts
Missing protective devices may cause balancing
weights or broken fan blades to be ejected and cause injuries.
• Take appropriate safety measures.
WARNING
Rotating device
Long hair and dangling items of clothing, jewelry and the like can
become entangled and be pulled into the device. Injuries can re
sult.
• Do not wear any loose-fitting or dangling clothing or jewelry
while working on rotating parts. Protect long hair with a cap.
WARNING
Ejected parts
If the motor is operated with attached fan blades, missing protective devices may allow balancing weights or broken fan blades to
be ejected and cause injuries.
• Take appropriate safety measures such as installing guard
grilles.
• Keep out of the exhaust zone.
2.7 HOT SURFACE
CAUTION
High temperature on electronics housing
Risk of burns
Ensure sufficient protection against accidental contact.
2.8 TRANSPORT
CAUTION
Transporting the motor
Crushing hazard
• Wear safety shoes and cut-resistant safety gloves.
• Transport the motor in its original packaging only.
• Secure the device so it cannot slip, e.g. by using a lashing strip.
2.9 STORAGE
Store the device, partially or fully assembled, in a dry and weatherproof manner in the original packaging in a clean environment.
Protect the device against environmental effects and dirt until final
installation.
We recommend storing the device for no longer than one year in
order to guarantee trouble-free operation and the longest possible
service life.
Even devices explicitly intended for outdoor use are to be stored
as described prior to commissioning.
Maintain the storage temperature, see Chapter 4.2 Transport and
storage conditions.
Make sure that all cable glands are fitted with dummy plugs.
2.10 DISPOSAL
Comply with all relevant local requirements and regulations when
disposing of the device.
