WARNING
Hazard from rotating rotor!
Provide the output elements with protection against
accidental contact.
Safety rules for working in electrical installations according to EN
50110-1:1996 (DIN VDE 0105-100):
- De-energize before starting work
- Isolate from electrical supply
- Secure against switching on again
- Check electrical deadness
- Earth and short-circuit
- Cover or cordon off adjacent parts which are electrically live
- Release for work
Connect the PE conductor to terminal .
Assembly requirements
- Proper installation is the responsibility of the manufacturer of the
system / machine.
- Connect the motor according to the wiring diagram in the
terminal box, and observe the data on the rating plate while
doing so.
- Adapt the connecting leads to the type of application and to the
anticipated voltages and current intensities.
- If the motor is supplied
by means of converters, high-frequency
current and voltage oscillations in the motor supply leads may
cause electromagnetic interference.
Only use shielded power and signal leads.
Observe the EMC instructions of the converter manufacturer.
- The connecting leads are to be equipped with a strain relief
device and the devices which protect against rotation and
transverse forces, and must be prevented from kinking.
Power terminal
1. The ends of the leads must not be stripped further than
necessary, i.e. the insulation must extend to the cable lug,
terminal or wire-end sleeve.
2. Match the size of the cable lugs or wire-end sleeves to the
dimensions of the terminal board connections and to the cross-
section of the power lead, lay parallel connecting leads if
necessary.
3. The cable lugs of the power terminals must rest directly on the
cable lugs of the motor winding.
4. Connect the PE conductor.
5. The inside of the terminal box must be kept clean and free from
cable residues and moisture.
6. For permanently secure joints, the screws and bolts of the
electrical connections (except the terminal blocks) must be
tightened to the torques specified in fig. 7.
7. The minimum air gaps specified in fig. 6 must be observed, both
when connecting and when re-arranging internal connecting
leads. Maintain minimum air gaps of 5.5 mm from live, non-
insulated parts. Avoid protruding wire ends.
8. Any entries which are not in use must be sealed dust and water-
tight, and the sealing elements must be screwed in firmly and
tightly.
9. Check the seals and sealing surfaces of the terminal box to
ensure that the degree of protection is maintained.
Pulse encoder and temperature sensor
- Connect with contact pins via the flanged socket fitted in the
terminal box.
Separate fan set 2CW83..
(radial fan 7.00, Fig.2.1)
1. Note the markings on the rating plate (7.32) and the
circuit diagram in the terminal box of the unit (7.01).
2. Connect the PE conductor to terminal .
3. Check the direction of rotation at the casing air inlet (directional
arrow).
CAUTION
Warning of motor damage!
Connecting the motor directly to a three-phase system will
destroy it.
Motors may only be driven with configured converters.
Ensure that the phase sequence is correct.
The gear encoder and temperature sensor are electrostatically
endangered components (EEC).
Do not touch the connections with your hands or with tools which
could be electrostatically charged!
Electric shock hazard!
Only use qualified, skilled personnel.
Observe the regulations for working in
electrotechnical plants.

Fitting the motor
3.1
Basic requirements
- Take note of and observe the information on the rating plate
(model, degree of protection), and warning and informative
notices on the motor.
- Observe the permitted transverse and axial forces as stated in
the project planning instructions.
- Check for compliance with the conditions at the assembly site.
- If lifting eye-bolts have been screwed in, they must be either
tightened or removed after the motor has been installed.
- Motors are intended for either horizontal or vertical installation
(see fig. 1).
In the case of deviation from the intended installation, consult
the manufacturer in advance and state the type designation and
serial number.
- The inflow and outflow of cooling air must be unimpeded.
Maintain the minimum distance
s
shown in fig. 4 between the air
inlets and outlets, and other components. Do not take heated
outgoing air in again.
- Remove any transportation securing devices and keep them in a
safe place.
- Measure the insulating resistance. Dry the winding if the values
are < 1 k
Ω
per volt of rated voltage.
- Place it on evenly, ensure that base or flange are well tightened,
avoid distortions.
- Turn the rotor by hand. If grinding noises occur, eliminate the
cause or contact the manufacturer.
- Avoid impermissible loads.
Assemble without hitting or putting pressure on the shaft end.
- The covers which were removed in order to screw the motor tight
(6.83, fig. 2) must be re-fitted before the motor is started up.
3.2
Immited vibrations, output elements
1PM6 hollow shaft motors are not fitted with a feather key as
standard.
The system’s vibrational behavior on site is affected by output
elements, the mounting conditions, the alignment, the installation
and external vibrations. This can change the vibration values of the
motor.
In the interests of reliable operation and a long bearing service life,
the vibration values specified in fig. 8 should not be exceeded.
If necessary, fully balance the rotor with the output elements
according to ISO 1940.
Suitable devices should always be used to push on or pull off the
output elements (e.g. the coupler disk, gear wheel).
As standard, the rotors are designed with a smooth shaft end, and
are balanced dynamically.
