Transport, Storage

WARNING
Danger during lifting and transporting
procedures!
Improper handling, unsuitable or defective
devices, tools etc. can cause injuries and/or
property damage.
Lifting devices, floor conveyors and lifting tackle
must conform to the currently valid regulations.
All the lifting eye-bolts provided (Fig. 2) should be used during
transport. Do not attach any additional loads.
Examples of standards: EU Directive for Machines 98/37 EEC,
appendix 1,
Regulations of the statutory industrial accident insurance institution
BGV D6, BGV D8, BGV D27, VBG 9a.
Store in a dry, low-dust and low-vibration place

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
informativenotices on the motor.
- Observe the permitted transverse and axial forces as stated inthe
project planning instructions.
- Check for compliance with the conditions at the assembly site.
- If lifting eye-bolts have been screwed in, they must be
eithertightened 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, consultthe manufacturer in advance and state the
type designation andserial number.
- The inflow and outflow of cooling air must be unimpeded.Maintain
the minimum distance s shown in fig. 4 between the airinlets and
outlets, and other components. Do not take heatedoutgoing air in
again.
- Remove any transportation securing devices and keep them in
asafe place.
- Measure the insulating resistance. Dry the winding if the
valuesare < 1 kO 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
thecause 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

Vibrations, balancing

WARNING
Hazard from rotating rotor!
Provide the output elements with protection
against accidental contact.
Hollow shaft motors 1PM4 are supplied without a feather key.
The site vibration response of the system is determined by the
output elements, the mounting conditions, the alignment, the
installation and the effects of external vibrations. This may cause a
modification of the motor vibration values.
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).

ENGLISH
As standard, the rotors are designed with a smooth shaft end, and
are balanced dynamically.

Coolant connection

Observe VDI guideline 3035 „Requirements on machine
tools" when using cooling lubricant 3035
2.2.7.2 Cable and accessory materials
2.2.7.7 Electric components
For operation of 1PH4 motors a closed coolant circuit with a heat-
exchanging unit is necessary. On the non-drirven end two threaded
joints here (6.85 Fig. 2) are to be removed. If the direction of the
coolant flow is not marked by arrows, either of the two holes can be
selected as the inlet and the other as the outlet.
Determine the cooling water flow and cooling capacity at rated
operation and maximum flow temperature +30°C (86
cooling water as shown in fig. 4, higher temperatures lead to
reduced output.
Warning of motor damage!
Do not operate the motors with cooling water that does
not contain an additive.
The cooling water generally has to have an anti-corrosion additive
(e.g. Tyfocor).
Maximum proportion 25%
Furthermore, the following values should be sufficient for the
cooling water.
Chemically neutral, clean, cleansed from solid particles.
Maximum size of any particles carried along 100 µm
If necessary equip with a particle filter
pH-Wert 6 - 7
Chloride < 50 ppm
Conductance (water only) < 500 mS/cm
Maximum operating pressure 3 bar
Fit pressure control valve in the supply line.
Do not use any non-ferrous metals in the cooling circuit (e.g. copper
or brass pipework) (electrolyte formation).
Add in a maximum of 40% antifreeze if there is a danger of frost
action. Use and dose as directed by the manufacturer.
The minimum requirements for cooling with oil are:
Kinematic viscosity
Specific thermal capacity
Density

Electrical connections

Electric shock hazard!
Only use qualified, skilled personnel.
Observe the regulations for working in
electrotechnical plants.
Safety rules for working in electrical installations as per
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
