1Safety information 1
1.1 Safety and application information
The safe use of electric motors
Danger
These electric motors are designed for use in industrial high-voltage installations. Rotating or
live and uninsulated parts pose a danger.
There is consequently a risk of fatal or severe personal injury or substantial damage to
property if the necessary covers are removed without authorization or if the equipment is
handled improperly, operated incorrectly or maintained inadequately.
If the motors are used outside industrial areas, the installation site must be safeguarded
against unauthorized access by means of suitable protection facilities (e.g. fencing) and
appropriate warning signs.
The persons responsible for the safety of the system are under an obligation to ensure that:
•the basic planning work for the system and all work relating to transportation, assembly,
installation, commissioning, maintenance and repairs are carried out by qualified persons
and checked by responsible, suitably skilled persons.
•these instructions and the motor documentation are made available at all times while
work is in progress.
•the technical data and specifications relating to the permissible installation, connection,
ambient and operating conditions are taken into account at all times.
•the system-specific erection and safety regulations are observed and personal protective
gear is used.
•work on these motors, or in the vicinity of these motors, by unqualified persons is
prohibited.
These instructions therefore only contain the information which is necessary for the motors
to be used by qualified persons in accordance with their intended purpose.
Note
We recommend engaging the support and services of your local Siemens service center for
all planning, installation, commissioning and maintenance work.

Notice
If the motor is not immediately commissioned, then it should be stored in a dry room which is
free from vibration and shock.
Transporting motors with a rotor shipping brace
Motors with cylindrical-roller bearings have a rotor shipping brace (shaft block), in order to
prevent the bearings from becoming damaged during transportation/shipping.
•Only remove this brace before fitting the drive element.
Notice
Take other suitable measures to axially fix the rotor if the motor has to be transported
after you have fitted the drive element.
[ID: 322.01]
3.3 Installation
Instructions relevant to safety
Caution
The enclosure components of electric motors can become very hot (possibly > 100 °C). Do
not touch enclosure components while the motor is running or immediately after it has been
running.
Caution
When positioning temperature-sensitive components (wires etc.), make sure that they are
not in contact with the motor enclosure.

Installation / Assembly
3.3 Installation
Siemens AG A5E00177602A
Operating Instructions V 2.0 1PH728 3-3
Notice
Also pay attention to the Technical Data on the rating plates on the motor enclosure.
Cooling conditions in general
•In the case of motors that are cooled by the ambient air, the cooling air must be able to
flow unimpeded to and from the motors. Hot discharged air must not be reinducted (see
also section "Cooling")
•Ventilation openings may only be covered by louvered covers in motors of those types of
construction in which the openings point downwards.
Cooling conditions for motors with pipe connection
Motors that are configured to allow pipes to be connected and/or for operation with a
separately driven fan must have pipes and a fan of suitable type and dimensioning mounted
and connected to them.
Please refer to the table below for the potential pressure drop inside the motor for motors
with a pipe connection:
Table 3-2 Pressure drop in motors with pipe connection
1PH7 28.
Volumetric flow (V) Pressure drop (Δp)
0.42 m3/s 600 Pa
Notice
Please consider the additional pressure drop that arises in the system when connecting the
pipes.
Also ensure that:
•you comply with the conditions of the IP degree of protection.
Higher IP requirements may necessitate the installation of suitable filters and special
positioning of the intake and outlet openings.
•units and wires are mounted without distortion.
•the shipping covers of the ventilation openings are removed.

Installation / Assembly
3.4 Mounting
Siemens AG A5E00177602A
3-4 Operating Instructions V 2.0 1PH728
Balancing quality
The rotors are dynamically balanced. In the case of shaft ends with feather keys, the method
used to balance the rotors can be identified from the following coding to be found on the end
face at the drive end of the shaft end:
•Code "H" means balancing with half a feather key (standard version); this means that in
order to maintain the balancing quality it may be necessary to cut back the part of the
feather key protruding from the drive element and the shaft profile if the motor has a short
output element.
•"F" means balancing with a whole feather key (optional version).
Make sure that the balancing method of the output element is correct!
Caution
A suitable tool must always be used for fitting and pulling off output elements.
The feather keys are only locked against falling out during shipping.
Noise emission
Motors of the 1PH728 series have a measuring surface sound pressure level Lp(A) of
approx. 74 dB(A) in a speed range from 0 through 3000 rpm.
The motors are certified for a wide range of installation and operating conditions. In some
cases these conditions (e.g. rigid or vibration-isolated foundation design, use of sound-
absorbing elements) can have a very great influence on noise emissions.
When evaluating the noise levels at the workplaces of the system operators, consider the
fact that the A-weighted sound pressure level (measured in accordance with DIN EN 21680
Part 1) of 70 dB(A) is exceeded when the three-phase motors are operated at nominal load.
[ID: 326.01]
3.4 Mounting
Requirements
In order to ensure smooth, vibration-free motor operation, a stable foundation design is
required, the motor must be precisely aligned, and the components that are to be mounted
on the shaft end must be correctly balanced.
Fixing by means of motor feet
If the motor needs to be aligned, position metal shims underneath the feet in order to prevent
the motor from suffering distortion.
The number of shims should be kept as low as possible i.e. stack as few as possible.
