If you require additional language versions, please contact the Siemens Service
Center.

Intended use of the machines

These machines are intended for industrial installations. They comply with the
harmonized standards of the series EN / IEC 60034 (VDE 0530). Their use in
hazardous areas is forbidden unless the marking on the rating plate expressly
permits this operation. If other/more wide-ranging demands (e.g. protection so that
they cannot be touched by children) are made in special cases – i.e. use in non­industrial installations – these conditions must have been complied with in the plant
or system itself when the motors are installed.

Note
Machine directive
Low-voltage motors are components designed for installation in machines in

accordance with the current Machinery Directive. The system may not be
commissioned until confirmation has been given that the final product is in
conformance with this directive (observe EN 60204-1 !).

Forced ventilation (optional): Cooling IC 416 in accordance with EN / IEC 60034-6

WARNING

Hot surfaces
Operating the machine without external fan results in overheating. This

may result in personal injury and material damage.
Never commission the machine without an external fan.

Cooling that does not depend on the speed is achieved by means of a separately
driven fan wheel (forced ventilation). Forced ventilation does not depend on the
operating state of the machine.

The fan wheel for the external flow of cooling air is powered by an independent
module and is enclosed by the fan cover.

4 Preparing for use

WARNING

Use lifting eyes
The machine must only be transported and lifted using the lifting eyes, in a position

that is appropriate for its type of construction. Otherwise, it could fall over or slip in
the lifting tackle.

This can result in death, serious injury, or material damage.

● Use all the lifting eyes on the machine.

● Any eyes that are screwed in must be tightly fastened.

● Eyebolts must be screwed in right up to their supporting surface.

● If necessary, use suitable, sufficiently-sized transport equipment such as lifting
straps (EN1492-1) and lashing straps (EN12195-2).

WARNING

Suspended transport
If several items of transport material are used for fastening, two straps must be able

to carry the whole load.

● Use additional, suitable means of support for transport and during installation.

● Secure the support equipment to prevent it from slipping.

Storage time

Turn the shafts 1x every year to avoid bearing brinelling. Prolonged storage periods
reduce the useful life of the bearing grease (aging).

Open bearings

● For open bearings e.g. 1Z, check the state of the bearing grease over 12 months.

● Replace the grease if it can be identified that the grease has lost oil content or
has become dirty (ingress of condensation leads to consistency changes of the
grease).

Closed bearings

● For closed bearings, replace the DE and NDE bearings after a storage time of 48
months

5.1 Safety instructions

WARNING

Hot surfaces
Electrical machines have hot surfaces.
Fatal or severe injuries and substantial material damage can occur if the

required covers are removed or if the machines are not handled,
operated, or maintained properly.

● Allow the machine to cool down before starting any work on it.

● Only remove covers in compliance with the applicable regulations.

● Operate the machines properly.
It must be ensured that parts (cables etc.) do not come into contact with

the machine enclosure.

NOTICE
Before start-up, please check that

● the customer has set the correct direction of rotation of the machine - e.g. by
decoupling from the driven machine - by taking appropriate measures!

● there are no temperature-sensitive parts (cables etc.), which are in contact with
the machine enclosure.

● condensation drain holes are always located at the lowest point of the motor!

Note
Please note the technical data on the rating plates on the machine enclosure.

5.2 Electromagnetic compatibility

Note
If the torque levels are very unequal (e.g. when a reciprocating compressor is being

driven), a non-sinusoidal machine current will be induced whose harmonics can have
an impermissible effect on the supply system and cause impermissible interference
emissions as a result.

Standard motors

14BMounting, installation

Note
Converter

● If operated with a frequency converter, the emitted interference varies in strength,
depending on the design of the converter (type, interference suppression
measures, manufacturer).

● Prevent the limit values stipulated by EN / IEC 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.

● You must observe the EMC information from the manufacturer of the converter.

● The most effective method of shielding is to conductively connect a shielded
machine supply cable to the metal terminal box of the machine (with a metal
screw connection) over a large surface area.

● On machines with integrated sensors (e.g. PTC thermistors), disturbance
voltages caused by the converter may occur on the sensor cable.

5.3 Balancing

CAUTION

Safety precautions

● The general touch protection measures for drive output elements must be
observed.

● Output elements may only be attached or withdrawn using the correct
equipment.

● The feather keys are only secured against falling out during shipping. If you
commission a machine without an output element, the feather keys must be
secured to prevent them from being thrown out.

The rotors are balanced dynamically. The balancing quality corresponds to vibration
severity grade "A" for the complete machine as standard. The optional vibration
severity grade "B" is indicated on the rating plate.

The declaration regarding the type of featherkey for balancing is generally marked on
the rating plate and optionally on the face of the shaft end.

Designation:

● As a standard measure, balancing is carried out dynamically with a half
featherkey (code "H") in accordance with ISO 8821.

● "F" means balancing with a whole featherkey (optional version).

● "N" means balancing without a featherkey (optional version).

7 Commissioning

7.1 Insulation resistance

WARNING

Working on electrical power installations
Only appropriately trained personnel may carry out this work.
Before starting commissioning, install all covers that are designed to

prevent active or rotating parts from being touched, or which are
necessary to ensure correct air guidance and thus effective cooling.

WARNING

Hazardous voltage at the terminals
Dangerous voltages are sometimes present on the terminals during and

immediately after measurement of the winding insulation resistance.
Contact with these can result in death, serious injury or material damage.

If any power cables are connected, check to make sure line supply
voltage cannot be connected. Once you have measured the insulation
resistance, discharge the winding by connecting to the ground potential.

Checking the insulation resistance

NOTICE
The insulation resistance needs to be checked prior to start-up and again after any

extended periods of storage or periods during which the equipment is not in
operation. Before you begin measuring the insulation resistance, please read the
operating manual for the insulation resistance meter you are going to use.
Disconnect any main-circuit cables that are connected to the terminals before
measuring the insulation resistance.

Note
If the critical insulation resistance is less than or equal to this value, the windings

must be dried or, if the fan is removed, cleaned thoroughly and dried.
Please note that the insulation resistance of dried, clean windings is lower than that

of warm windings. The insulation resistance can only be properly assessed after
conversion to the reference temperature of 25 °C.

16BCommissioning

Note
If the measured value is close to the critical value, you must check the insulation

resistance at suitably frequent intervals.

Measuring the insulation resistance

1. Before you begin measuring the insulation resistance, please read the operating

manual for the insulation resistance meter you are going to use.

2. Disconnect any main circuit cables from the terminals before measuring the

insulation resistance.

3. Where possible, measure the insulation resistance of the winding with respect to

the motor enclosure when the winding temperature is between 20 ... 30 °C.
Different insulation resistance values apply for other temperatures.

4. When measuring, wait until the final resistance value is reached. This is reached

after approximately one minute. Then read off the insulation resistance.

Limit values of the stator winding insulation resistance

The following table indicates the measuring circuit voltage and the limit values for the
minimum insulation resistance and the critical insulation resistance of the stator
winding.

Note the following:

● If the measurements are performed at winding temperatures ≠ 25 °C, convert the
measured value to the reference temperature of 25 °C in order to be able to
compare the values with the table above.

– The insulation resistance halves every time the temperature rises by 10 K.
– The resistance doubles every time the temperature falls by 10 K.

● Dry, new windings have a typical insulation resistance of more than

insulation resistance value close to the minimum value could be due to moisture
and/or dirt accumulation.

● During operation, the insulation resistance of the windings can fall to the critical
insulation resistance due to ambient and operational influences. The critical
insulation resistance value for a winding temperature of 25 °C can be calculated
by multiplying the rated voltage (kV) by the specific critical resistance value
(0,5 MΩ / kV).

Example:
Critical resistance for rated voltage U
690 V x 0,5 MΩ / kV = 0,345 MΩ

Critical insulation resistance reached or fallen below
If the critical insulation resistance is reached or fallen below, this can result in

damage to the insulation or voltage flashovers.

● Contact your Siemens Service Center.

● If the measured value is close to the critical value, you must check the

insulation resistance at suitably frequent intervals.

Measures before commissioning

Once the system has been correctly installed, you should check the following prior to
commissioning:

● The machine has been assembled and aligned correctly.

● The machine has been connected so that it rotates in the direction specified.

components, especially if these contain plastics.

9.1 Maintenance

9.1.1 Regreasing (optional)

General

As a standard feature, the machines have rolling-contact bearings which are
permanently lubricated with grease (UNIREX N3, made by ESSO). A regreasing
device is possible as an option. In this case, you can find information about
relubrication intervals, quantities and types of grease, and, if required, additional data
on the rating plate or lubricant plate.

Note
Do not mix different types of grease!

Standard motors

58 56100000002001, 02/2013

18BMaintenance

Prolonged storage periods reduce the useful life of the bearing grease. Check the
condition of the grease if the equipment has been in storage for more than 12
months. If the grease is found to have lost oil content or to be contaminated, the
machine must be immediately relubricated before commissioning. For information on
permanently-greased bearings, please refer to the section titled Bearings (Page 60).

Note
Regreasing

1. Clean the grease nipples at the drive end and non-drive end.

2. Press in the type and quantity of grease specified (see rating/lubricant plate data).

● Please observe the information on the rating and lubricant plates.

● Regreasing should be carried out when the machine is running (max. 3600 rpm)!

The bearing temperature rises sharply at first, then drops to the normal value again
when the excess grease is displaced out of the bearing.

9.1.2 Cleaning

Cleaning the greasing channels and used grease chambers

The used grease collects outside each bearing in the used grease chamber of the
outer bearing cap. When replacing bearings, remove the used grease.

Note
You have to separate the active parts of the bearings to replace the grease that is in

the greasing channel.

Cleaning the cooling air passages

Regularly clean the cooling air passages through which the ambient air flows,
e.g. using dry compressed air.

Note
Never direct compressed air in the direction of the shaft outlet or machine openings.

In the case of machines with textile fan covers, regularly remove fluff balls, fabric
remnants, and similar types of contamination (particularly at the air passage opening
between the fan cover and cooling fins of the machine enclosure) to ensure that the
cooling air can flow without obstruction.
