1.4 Safety Precautions
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input, DC supply, or load sharing.
Failure to perform installation, start-up, and maintenance
by qualied personnel can result in death or serious
injury.
•Only qualied personnel must perform instal-
lation, start-up, and maintenance.
•Before performing any service or repair work,
use an appropriate voltage measuring device to
make sure that there is no remaining voltage on
the frequency converter.
WARNING
UNINTENDED START
When the drive is connected to AC mains, DC supply, or
load sharing, the motor can start at any time.
Unintended start during programming, service, or repair
work can result in death, serious injury, or property
damage. The motor can start with an external switch, a
eldbus command, an input reference signal from the
LCP or LOP, via remote operation using MCT 10 Setup
Software, or after a cleared fault condition.
To prevent unintended motor start:
•Press [O/Reset] on the LCP before
programming parameters.
•Disconnect the drive from the mains.
•Completely wire and assemble the drive, motor,
and any driven equipment before connecting
the drive to AC mains, DC supply, or load
sharing.
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors,
which can remain charged even when the frequency
converter is not powered. High voltage can be present
even when the warning LED indicator lights are o.
Failure to wait the specied time after power has been
removed before performing service or repair work can
result in death or serious injury.
•Stop the motor.
•Disconnect AC mains and remote DC-link power
supplies, including battery back-ups, UPS, and
DC-link connections to other frequency
converters.
•Disconnect or lock PM motor.
•Wait for the capacitors to discharge fully. The
minimum duration of waiting time is specied
in Table 1.3.
•Before performing any service or repair work,
use an appropriate voltage measuring device to
make sure that the capacitors are fully
discharged.
Voltage [V] Power range [kW (hp)] Minimum waiting time
(minutes)
3x200 0.25–3.7 (0.33–5) 4
3x200 5.5–11 (7–15) 15
3x400 0.37–7.5 (0.5–10) 4
3x400 11–90 (15–125) 15
3x600 2.2–7.5 (3–10) 4
3x600 11–90 (15–125) 15
Table 1.3 Discharge Time
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the
frequency converter properly can result in death or
serious injury.
•Ensure the correct grounding of the equipment
by a certied electrical installer.

WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment
can result in death or serious injury.
•Ensure that only trained and qualied personnel
perform installation, start-up, and maintenance.
•Ensure that electrical work conforms to national
and local electrical codes.
•Follow the procedures in this manual.
CAUTION
INTERNAL FAILURE HAZARD
An internal failure in the frequency converter can result
in serious injury when the frequency converter is not
properly closed.
•Ensure that all safety covers are in place and
securely fastened before applying power.

The eciency of the frequency converter is dened as the
ratio between the power output and the power input.
Start-disable command
A stop command belonging to the group 1 control
commands, see Table 1.4.
Stop command
See Table 1.4.
Analog reference
A signal transmitted to the analog inputs 53 or 54. It can
be voltage or current.
•Current input: 0–20 mA and 4–20 mA
•Voltage input: 0–10 V DC
Bus reference
A signal transmitted to the serial communication port (FC
port).
Preset reference
A dened preset reference to be set from -100% to +100%
of the reference range. Selection of 8 preset references via
the digital terminals.
RefMAX
Determines the relationship between the reference input at
100% full scale value (typically 10 V, 20 mA) and the
resulting reference. The maximum reference value set in
parameter 3-03 Maximum Reference.
RefMIN
Determines the relationship between the reference input at
0% value (typically 0 V, 0 mA, 4 mA) and the resulting
reference. The minimum reference value is set in
parameter 3-02 Minimum Reference.
Analog inputs
The analog inputs are used for controlling various
functions of the frequency converter.
There are 2 types of analog inputs:
•Current input: 0–20 mA and 4–20 mA
•Voltage input: 0–10 V DC
Analog outputs
The analog outputs can supply a signal of 0–20 mA, 4–
20 mA, or a digital signal.
Automatic motor adaptation, AMA
The AMA algorithm determines the electrical parameters
for the connected motor at standstill and compensates for
the resistance based on the length of the motor cable.
Digital inputs
The digital inputs can be used for controlling various
functions of the frequency converter.
Digital outputs
The frequency converter provides 2 solid-state outputs that
can supply a 24 V DC (maximum 40 mA) signal.
Relay outputs
The frequency converter provides 2 programmable relay
outputs.
ETR
Electronic thermal relay is a thermal load calculation based
on present load and time. Its purpose is to estimate the
motor temperature and prevent overheating of the motor.
Initializing
If initializing is carried out (parameter 14-22 Operation
Mode), the programmable parameters of the frequency
converter return to their default settings.
Parameter 14-22 Operation Mode does not initialize
communication parameters, fault log, or re mode log.
Intermittent duty cycle
An intermittent duty rating refers to a sequence of duty
cycles. Each cycle consists of an on-load and an o-load
period. The operation can be either periodic duty or none-
periodic duty.
LCP
The local control panel (LCP) makes up a complete
interface for control and programming of the frequency
converter. The control panel is detachable on IP20 units
and xed on IP54 units. It can be installed up to 3 m
(9.8 ft) from the frequency converter, that is, in a front
panel with the installation kit option.
Lsb
Least signicant bit.
MCM
Short for mille circular mil, an American measuring unit for
cable cross-section. 1 MCM = 0.5067 mm2.
Msb
Most signicant bit.
On-line/O-line parameters
Changes to on-line parameters are activated immediately
after the data value is changed. Press [OK] to activate o-
line parameters.

PI controller
The PI controller maintains the desired speed, pressure,
temperature, and so on, by adjusting the output frequency
to match the varying load.
RCD
Residual current device.
Set-up
Parameter settings in 2 set-ups can be saved. Change
between the 2 parameter set-ups and edit 1 set-up, while
another set-up is active.
Slip compensation
The frequency converter compensates for the motor slip by
giving the frequency a supplement that follows the
measured motor load keeping the motor speed almost
constant.
Smart logic control (SLC)
The SLC is a sequence of user-dened actions executed
when the associated user-dened events are evaluated as
true by the SLC.
Thermistor
A temperature-dependent resistor placed where the
temperature is to be monitored (frequency converter or
motor).
Trip
A state entered in fault situations, for example, if the
frequency converter is subject to an overtemperature or
when the frequency converter is protecting the motor,
process, or mechanism. Restart is prevented until the cause
of the fault does not exist and the trip state is canceled by
activating reset or, sometimes, by being programmed to
reset automatically. Do not use trip for personal safety.
Trip lock
A state entered in fault situations when the frequency
converter is protecting itself and requiring physical
intervention, for example, if the frequency converter is
subject to a short circuit on the output. A locked trip can
only be canceled by cutting o mains, removing the cause
of the fault, and reconnecting the frequency converter.
Restart is prevented until the trip state is canceled by
activating reset or, sometimes, by being programmed to
reset automatically. Do not use trip lock for personal safety.
VT characteristics
Variable torque characteristics used for pumps and fans.
VVC+
If compared with standard voltage/frequency ratio control,
voltage vector control (VVC+) improves the dynamics and
the stability, both when the speed reference is changed
and in relation to the load torque.
