ARNINGS
1.1 R
OTATING ELEMENTS AND SHAFTS
When you work, you should use suitable protection and safety wears and
barriers to prevent the danger of injury or death.
1.2
H
YDRAULIC AND LUBRICATION
Use proper personal protection equipment and clothes
Follow all safety measurements
Stop first the driving motor and/or engine
Prevent then the starting of driving motors or engines
Check that there is no high pressure present
The oil can be hot
Use only proper quality tools
Protect the environment
Due to safety considerations pipe fittings, connections and components
must not be loosened as long as the system is pressurized.
1.3 T
HRUST AT PROPULSOR
Propulsor give thrust during some test or service operations.
1.4 H
YDRAULIC PRESSURE
There can be pressure at propulsor lubrication system. Give the pressure come out
before you open plugs totally.
1.5 O
IL LEAKAGE
Do not open the protection tube, because then the oil can come out from propulsor.
1.6 H
OT WATER
Be careful with hot water.
1.7 R
OTATING OR MOVING MACHINERY
Coming into contact with this machinery is extremely dangerous and may cause
death or severe injury.
1.8 AC
AND AUXILIARY POWER CIRCUITS
The components of the AC and power circuits and terminals are live, when the
equipment is connected to supply potential. Coming into contact with this
voltage is extremely dangerous and may cause death or severe injury.
The motor control unit SMU has three motor supplies and one control
supply.
The motor terminals and brake terminals are live when the frequency converter
is connected to mains, even if the motor is not running.
The frequency converter has a large capacitive leakage current.

AFETY
2.1 G
ENERAL
These instructions are meant for professional use. Operation, service and maintenance
personal should be well-trained professionals.
2.2 I
NSTALLATION
The propulsor system is meant for fixed installations only.
2.3
E
LECTRIC
W
ORK
Do electric work only, when the supply isolation devices at main
switchboard are locked open.
Do not make temporary connections
Before connecting the electric supply, check that all devices are clean and
dry.
Open the protection devices and voltage switches of the control system
before you connect supply voltage.
Take care that nobody is working or touching the electric connections,
when you connect the supply voltage, open the circuit breakers before you
connect the shipside supply!
2.4 M
EASUREMENTS
Do not perform any measurements when the equipment is connected to AC
control or power circuits supply potential.
After disconnecting the frequency converter from the mains, wait until the
fan stops and indicators on the keypad go out. Wait 5 more minutes before
doing any work on power or AC side connections. Do not even open the
cover before this time has expired.
Do not perform any voltage withstand tests on any part of the frequency
converter. This test should be made special procedure.
Prior to measurements on the motor or the motor cable, disconnect the
motor cable from frequency converter.
Do not touch the IC or other electronic circuits on circuit boards. Static
voltage discharge may damage the components.
Before connecting the AC control or power circuits supply potential, make
sure, that all covers and cabinet doors are closed.
2.5
C
ONTROL CIRCUITS
Do not touch the IC-circuits on the circuit boards. Static voltage discharge
may damage the components.
You should use carefully transmitters and other instruments, because their
signal circuits can destroy at wrong connection
The potentiometers at control lever are very sensitive instruments. Be very
careful, when you test and connect them.
Static charges can damage electronic devices. Discharge the electrical
charge from your body before opening and configuring the device. To do
so, touch a grounded surface, e.g. the metal housing of the switch cabinet.

2.6
E
LECTRIC MOTORS
Before starting the motor, check that the motor is mounted properly and
ensure that the machine connected to the motor allows the motor to be
started.
Set the maximum motor speed (frequency) according to the motor and the
machine connected to it.
Before reversing the motor shaft rotation direction make sure that this can
be done safely.
Make sure that no power correction capacitors are connected to the motor
cable.
Make sure that the motor terminals are not connected to mains potential.
2.7
A
LTERNATING CURRENT CIRCUITS
Do not perform any measurements when the frequency converter is
connected to the mains.
After disconnecting the frequency converter from the mains, wait until the
fan stops and the indicators on the keypad go out (if no keypad is attached
see the indicators on the cover). Wait 5 more minutes before doing any
work on Converter connections. Do not even open the cover before this
time has expired.
Do not perform any voltage withstand tests on any part of Converter. There
is a certain procedure according to which the tests shall be performed.
Ignoring this procedure may result in damaged product.
Prior to measurements on the motor or the motor cable, disconnect the
motor cable from the frequency converter.
Before connecting the frequency converter to mains make sure that the
Converter front and cable covers are closed.
The components of the power unit of the frequency converter are live when
converter is connected to mains potential. Coming into contact with this
voltage is extremely dangerous and may cause death or severe injury.
The control unit is isolated from the potential.
The motor terminals U, V, W and the DC-link/brake resistor terminals –/+
and disc brake terminals are live when converter is connected to mains,
even if the motor is not running.
The frequency converter has a large capacitive leakage current.
2.8 L
OW VOLTAGE
The control I/O-terminals are isolated from the mains potential. However,
the relay outputs and other I/O-terminals may have a dangerous control
voltage present even when converter is disconnected from mains.

3 E
ARTHING AND EARTH FAULT PROTECTION
3.1 C
ONTROL UNITS
The frequency converter must always be earthed with an earthing
conductor connected to the earthing terminal.
The control units must always be earthed with an earthing conductor
connected to the earthing terminal.
The earth fault protection inside the frequency converter protects only the
converter itself against earth faults in the motor or the motor cable.
Due to the high capacitive currents present in the frequency converter, fault
current protective switches may not function properly. If fault current
protective switches are used they must be tested with the drive with earth
fault currents that are possible to arise in fault situations.
The mounting rail must be connected to ground potential. This is the only
way to guarantee that the integrated surge voltage protection functions and
that the shield of the bus conductor makes contact effectively.
3.2 C
ONTROL PANELS
The control panels must always be earthed with an earthing conductor
connected to the earthing terminal.
3.3 P
ROPULSOR
The housings of electric steering and lubrication pumps should be
connected with an earthing conductor connected to the earthing terminal.
The propulsor should be connected with an 25 mm2 earthing conductor
connected to the earthing terminal.

NVIRONMENT PROTECTION
4.1 M
ACHINE DEMOLITION
If the machine must be scrapped, it, should become non-operational:
Disassemble the various parts.
Disconnect any motor unit.
But first after having completely emptied all the oil from propulsor unit and its auxiliaires
unit.
4.2 E
COLOGY INFORMATION

lubricants must comply with environmental restrictions, without polluting the soil, water
or air. The party receiving the materials is responsible for carrying out the operation in
conformity with the current standards in force in the country in which the machine is
used.
4.3 I
