Safety Guidelines
This manual contains notices which you should observe to ensure your own personal safety as well as
to avoid property damage. The notices referring to your personal safety are highlighted in the manual
by a safety alert symbol, notices referring to property damage only have no safety alert symbol.
Danger
indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
Warning
indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Caution
used with the safety alert symbol indicates a potentially hazardous situation which, if not avoided, may
result in minor or moderate injury.
Caution
used without safety alert symbol indicates a potentially hazardous situation which, if not avoided, may
result in property damage.
Notice
used without the safety alert symbol indicates a potential situation which, if not avoided, may result in
an undesirable result or state.
When several danger levels apply, the notices of the highest level (lower number) are always
displayed. If a notice refers to personal damages with the safety alert symbol, then another notice may
be added warning of property damage.

1-2 Operating Instructions - Three-phase induction motor - AH 180
Notice
Attention means that an undesirable result or state might occur if the relevant instructions
are not followed.
Note
Note indicates important information concerning the product, its use or the corresponding
section of the documentation which must be given special attention and is recommended to
be adhered to because of the potential benefits.
Compliance with intended use
Please pay close attention to the following:
Warning
The electrical equipment contains items that are at a dangerous voltage.
Before any work may be carried out, it must be ensured that the equipment has been set to
zero potential.
Only qualified persons may work with this equipment.
These persons must be familiar with all instructions and measures in this documentation that
are relevant for safety.
Faultless and safe operation of this equipment requires appropriate transport, storage,
installation and assembly as well as careful operation and maintenance.
The equipment may only be used for single purpose applications explicitly described in the
catalog and in the technical description and it may only be used along with third-party
devices and components recommended by Siemens.
Failing to adhere to these instructions may result in severe injury and/or damage to property.
National safety regulations must be closely observed.

SIEMENS AG, 1PH718 A5E00215729A V 2.0
Operating Instructions - Three-phase induction motor - AH 180 1-3
Danger
These electric motors are designed for use in industrial power systems. 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.
The instructions and the motor documentation are available in the languages specified in the
supply contracts.
Note
We recommend engaging the support and services of your local Siemens service center for
all planning, installation, commissioning and maintenance work.

Description
The three-phase motors of the 1PH7 series are externally ventilated, low-voltage induction
motors with a squirrel-cage rotor and a separately driven fan unit mounted as standard. They
are of an enclosed design, with a cooling circuit (cooling method IC06; DIN EN IEC 60034-
6).

Figure 2-2 Cooling process for ventilating from the D-end to the N-end (basic type)
(1) Cover sheet
A KTY B4 temperature sensor is installed in the stator winding to monitor the winding.
Depending on the order, various additional devices, such as sensor systems can be installed
or built on.
Notice
A minimum clearance of 100 mm from devices added on by the customer must be observed
at the air intake opening and at the air outlet openings, in order to guarantee the necessary
flow of cooling air.
Caution
Missing cover sheets can result in a considerably reduced cooling capacity and thus cause
an inadmissible temperature rise within the motor.
Please ensure that the cover sheets are always mounted.

3.1 Transport, storage
Instructions relevant for safety
Please observe the following instructions on the transportation and storage of motors.
Caution
Motors may only be attached to and hoisted by the main eyebolts that are located at the end
shields. Auxiliary eyebolts, e.g. on fan cowls and cooler attachments, are suitable only for
hoisting the respective parts.
To hoist the motor, in particular at attachments and built-on assemblies, use suitable cable-
guidance or spreading equipment.
Observe the lifting capacity of the hoisting gear.
(See rating plate for weight.)

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.

after you have fitted the drive element.
[ID: 324]
3.2 Installation
Instructions relevant for 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.
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 "Cooling").
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:
