Marine motors made according to the requirements of Polish Register of
Shipping are manufactured in the degree of protection IP 55.
Direct-on starting is used in motors. They can operate when voltage deviations do not exceed ± 10% of the motor rated voltage. All of the rated data refer
to the rated voltage.
If voltage deviations exceed ± 10 % of the rated voltage motors should
not be started. This rule can be omitted only if motor has a suitable heat reserve for
the specific application. Maximal heating temperature of the motor winding can
not exceed + 155oC (for insulation class F). Having carried out tests only the
branch specialist can decide about it; using Polish Standard PN-89/E-05012 is recommended.
Each motor must be protected against overload and short-circuit by
protections selected by an user in accordance with Polish Standard PN-89/E-05012
and recommendations of BESEL.

Parts of driven device coupled to the motor shaft directly should be balanced dynamically with an accuracy of 5 mm, not less.
2.1. ACTIVITIES BEFORE THE INSTALLATION OF A MOTOR
Before you mount the motor to a motored device:
a) check if the rotor turns freely,
b) check if parts of the device which is coupled to the motor shaft are balanced
dynamically with the required accuracy,
c) put on parts of a motored device sliding or pushing them lightly without exerting pressure on bearings. Otherwise you will cause damage. At the same time
the motor shaft should be supported on the non-drive end stiffly so that the
pressure should not cause either damage of bearings or damage of a spring
washer which cancels axial play of the rotor,
d) after fixing the motor in a device check whether there is the minimal distance
(14 mm) between the fan cover and other parts, whether the holes in the cover
are not stopped down.
Caution:
Access of cooling air to the motor housing cannot be made difficult.

2.2. CONNECTING THE MOTOR TO THE MAINS
2.2.1. Three-phase motors made for voltage base 230/400
220/380 V or
220 ÷ 240 / 380 ÷ 420 V can be connected:
a) to the mains with line-to-line voltage: 3 x 400
380 V, 3 x 380-420 V when the
motor winding is star connected,
b) to the mains with line-to-line voltage: 3 x 230
220 V, 3 x 220-240 V when the
motor winding is delta connected.
Three-phase motors of frame size 80, 71 are made as:
a) single-speed with the pole number 2p = 2, 4, 6, 8
b) two-speed with the pole number:
2p = 4 / 2ü
ý - single-winding
2p = 8 / 4 þ
2p = 8 / 6 ü
ý - double-winding
2p = 6 / 4þ
and with other number of poles - as requested.
Three-phase motors of frame size 63 and 56 are made as:
a) single-speed with pole number 2p = 2, 4.
The ways of winding connection and connecting them to the mains are
presented on wiring diagrams in the annex No. 1 of this Manual. The wiring diagram is on the inside of the lid of a terminal box. Motors made for specific voltages can be connected to the mains with line-to-line voltage corresponding to the
voltage placed on a rating plate.

Single-phase motors with a run capacitor , frame size 56, 63, 71, 80 and
90 are made as single-speed with the number of poles 2p = 2 and 2p = 4.
The winding and capacitor connexions on the terminal board , connecting them to the mains for clockwise and anticlockwise rotation are presented on
wiring diagrams on the annex No.1 of this Manual. Wiring diagrams are on the
inside of the lid of a terminal box.
Motors made for specific voltages can be connected to the mains of rated
voltage corresponding to the voltage marked on the rating plate of the motor.

5. TRANSPORT
Motors must be transported only under cover that protects them against
getting wet or damp.
Motor cartons should guarantee appropriate protection against mechanical
damages, shocks and dust.
During transport they should guarantee proper protection against damages
of the shaft end, terminal box, fan cover and varnish coat.
Motors should be transported in crates, metallic pallets or carton boxes.
Motors must not move inside containers which must be stuck.
5.1. MOTOR WEIGHTS
Motor weights are different for different types of the same frame sizes according to output, different mounting systems and other added specific details.
The table below contains maximal (approximate) motor weights as function of stacking length (A,B,C).

6. STORAGE
Motors should be stored in dry airy containers free from gases, liquids
and causting vapours which are harmful for the winding insulation and parts of
the motor.
Motors must not be kept in rooms where fertilisers, chlorinated lime,
aciors and chemical agents etc. are gathered. The temperature of the environment
where motors are stored must not be lower than 278 K (+ 5oC) and relative humidity must not exceed 70 %.
Motors stored more than 2 years since the production date (after warranty period) should be renovated, what includes:
a) outside cleaning of the motor,
b) checking if bearings operate in a correct way and, if not, damaged bearings
must be replaced,
c) measurement of the winding insulation resistance (in cool state) and if it is
lower than 20 MW motors must be dried in a temperature not higher than 353
K (+80oC).
The shaft end must be protected against corrosion by the layer of corrosion preventing grease or easily removed varnish.
