Safety and operating instructions for converter-fed
low-voltage three-phase motors
in conformity with the low-voltage directive 73/23/EEC
1 Danger
In operation, electric motors have hazardous, live and rotating
parts, and possibly also hot surfaces. All operations serving
transport, connection, commissioning and regular
maintenance are to be carried out by qualified, responsible
technical personnel. (Observe VDE 0105; IEC 364.)
Improper conduct can cause severe personal injury and
damage to property. The applicable national, local and
plant-specific specifications and codes of conduct must
be complied with. The warning and instruction plates on the
motor must be complied with.
2 Intended use
These motors are intended for service in industrial and commercial
installations. They comply with the harmonized standards of the
series EN60034 (VDE 0530). Their use in areas exposed to
explosion hazard i s prohibited, unless they are
supplied for this purpose (pay attention to additional notes). In special
cases - where these motors are used in a non-industrial environment
- extra safety precautions (such as touch protection for children) must
be provided by the owner or user of the equipment during installation.
The motors are rated for ambient temperatures from -15 °C to +40 °C and
for installation at altitudes of ≤ ≤ ≤ ≤ ≤ 1000 m above sea level. If different
information is given on the rating plate, always be sure to follow it. The
conditions at the place of use must conform with all the rating plate data.
Low-voltage motors are components for installation in machines
as defined by the machine directive 89/392/EEC. Commissioning
is prohibited until such time as the end product has been proved
to conform to the provisions of this directive 89/392/EEC, among
other things. (Account is to be taken of EN 60204-1.)
Plants and machines equipped with converter-fed low-voltage three-
phase motors must satisfy the requirements of the EMC directive 89/
336/EEC.
Proper installation is the responsibility of the plant installer. The signal
and power cables must be shielded.
Account is to be taken of the converter manufacturer's EMC
instructions!
3 Transport, storage
Notify the transport company immediately of any damage discovered
after delivery; if necessary the equipment is not to be commissioned.
For transport, use only the openings, lifting eyes, etc., provided. Make
sure that the lifting eyes are screwed tight. Do not attach any additional
loads. Keep the lifting capacity of the hoisting gear in mind.
Before commissioning, remove shipping braces and keep them in a
safe place. If motors are put into storage, make sure that they are kept in
a dry, dust-free and low-vibration (v
(bearing standstill damage).
Measure the insulation resistance before putting the motors into operation
for the first time. Dry out the winding if the insulation resistance is ≤ ≤ ≤ ≤ ≤ 1k
per volt of rated voltage value.
4 Installation
Make sure that the motor is properly supported, that the feet or flange are
firmly fixed and that directly-coupled motors are in alignment (avoid
distortion). Rotate rotor by hand to ensure that it does not rub against
anything.
Always make use of suitable devices for fitting and removing drive
elements (belt wheel, coupling ...) and heat or cool them as necessary.
At all other times drive elements must be kept covered for the sake of
touch protection. Avoid undue stressing (such as excessive belt tension).
If in doubt, refer to the catalog or specification.
The balance data is given on the shaft end face or rating plate (H = half
featherkey balancing, F = full featherkey balancing). Keep the balance in

mind when fitting the drive element (ISO1940)! With half featherkey
balancing, cut off the protruding end of the featherkey if necessary.
Do not impede free circulation of air around self-ventilated motors or
through forced-ventilated motors.
5 Electrical connection
All work must be done only by qualified technical personnel on
disconnected motors that are at standstill and have been secured to
prevent reconnection. The same applies to auxiliary circuits (such as
space heating, brake, transmitter).
Check that the equipment is dead!
CAUTION: The motors must be operated with the appropriate converters.
Operation on the three-phase supply is not permitted and can destroy
the motor!
Pay attention to the information given on the rating plate and in the circuit
diagram in the terminal box or operating instructions.
Pay attention to compatibility between transmitter/sensor signals and
the analyzer.
Transmitters and sensors may contain electrostatically sen-
sitive components (ESC); pay attention to ESC measures if
applicable!
Disassembly, assembly and adjustment of transmitters must be carried
out in accordance with the relevant instructions.
The connection must be made so that there is a permanent and safe
electrical connection (no protruding wire ends). Make use of the cable
lugs or end sleeve provided. Make a good and secure protective
conductor connection.

For terminal box connection, make sure that the clearances in air
between non-insulated live parts are at least 5.5 mm!
No foreign matter, dirt or moisture must be present in terminal boxes or
plugs. Close unused openings for cable entry and the terminal boxes
themselves in a dust-tight and waterproof manner.
When connecting and installing accessories (e.g. tachometer generators,
impulse transmitters, brakes, temperature sensors, airflow monitors ...),
it is essential to comply with the relevant information, if necessary
contact the motor manufacturer. If there are no instructions available for
the repair of a damaged accessory, then the repair must be made in a
SIEMENS specialist workshop.
Where motors are fitted with brakes, the brake must be checked for
proper functioning before the motor in put into operation for the first time.
6 Operation
Secure featherkeys before the motor is tested by running it without
drive elements. Check the direction of rotation with the motor uncoupled
(refer to Section 5 above).

operation (exactly information, see operating instruction).
In the event of changes in normal operating behaviour, such as increased
temperature, noise, vibration, switch the motor off if in doubt. Find
out the cause of the trouble; consult the manufacturer if necessary. Even
when the motor is only on test, do not put safety equipment out of
operation.
Where motors are operating in a dusty or dirty atmosphere, clean the air
passages regularly.
Fit new bearings or replenish bearing grease at the intervals specified by
the manufacturer, or not less frequently than every 3 years.
7 Further information
Further information is given in our maintenance instructions (ENG-
LISH / GERMAN). If your write to us quoting the motor type and
number, we shall be pleased to send you the appropriate mainte-
nance instruction.
Keep these safety and operating instructions in a safe place!
