maintenance and repair may only be carried out by qualified personnel, in strict ob-
servation of:
– The relevant detailed operating instructions
– The warning and safety signs on the servomotor/gearmotor
– All other project planning documents, operating instructions and wiring dia-
grams belonging to the drive
– The specific regulations and requirements for the system
– National / regional regulations governing safety and the prevention of accidents
• Never install or start up damaged products

Safety Notes
2.7 Transport/storage
Follow the instructions on transportation, storage and proper handling. Comply with the
requirements for climatic conditions stated in section 'Technical Data'.
Inspect the shipment immediately upon receipt for any damage that may have occurred
during transportation. Inform the shipping company immediately. If you notice any trans-
port damage, do not startup the servomotor, but contact the SEW-EURODRIVE Ser-
vice.
Remove securing devices used for transportation prior to startup.
Tighten installed transportation eyebolts. They are only designed for the weight of the
servomotor / gearmotor; do not attach any additional loads.
The installed lifting eyebolts comply with DIN 580. The loads and regulations specified
in this standard must always be observed. If the gearmotor has 2 suspension eye lugs
or lifting eyebolts, then you should also use both suspension eye lugs for attaching
transport ropes. In this case, the tension force vector of the slings must not exceed a
45° angle in accordance with DIN 580.
Store the servomotor in a dry, dust-free environment if it is not to be installed straight
away.
2.8 Mounting/installation
Observe the instructions in section 4, "Mechanical Installation" and section 5, "Electrical
Installation".
The units must be installed and cooled according to the regulations and specifications
in the corresponding documentation.
Protect the synchronous servomotors from excessive strain. Ensure that components
are not deformed, particularly during transportation and handling.
The following application is prohibited unless the unit is explicitly designed for such use:
• Use in areas exposed to harmful oils, acids, gases, vapors, dust, radiation, etc.

4.1 Required tools/resources
• Standard tools
• Mounting device
• Operation with conductor end sleeves: Crimping tool and conductor end sleeves
• Crimping tool for plug connectors in case customers want to assemble cables them-
selves
• Removal tool
4.2 Before you start
Do only install the servomotor if the following conditions are met:
• The specifications on the nameplate of the servomotor correspond to the supply sys-
tem (line-powered drive) or the output voltage of the servo inverter (inverter-powered
drive).
• The drive is undamaged (no damage caused by transportation or storage)
• The ambient temperature corresponds to the information on the nameplate and on
the order confirmation.
• The surrounding area is free from oils, acids, gases, vapors, (ionizing) radiation, etc.
• The installation altitude must be no higher than 1000 m above MSL, otherwise the
drive must be designed to meet the special environmental conditions. In case of de-
viations, see nameplate/order confirmation.
4.3 Preliminary
Thoroughly clean the shaft ends and make sure that they are free from anti-corrosion
agent, dirt or the like. Use a commercially available solvent. Make sure that the solvent
does not come into contact with the bearing or sealing rings as it may damage the ma-
terial.
CAUTION!
Observe the safety notes in section 2 during installation.
STOP!
The bearing and the sealing rings can be damaged if exposed to solvents.
Possible material damages!
• Protect the bearing and sealing rings from exposure to solvents.

Mechanical Installation
4.3.1 Long-term storage of servomotors
• The service life of the ball bearing grease is reduced after storage periods exceeding
one year.
• Check whether the servomotor has absorbed moisture as a result of being stored for
a long time. Measure the insulation resistance with a measurement voltage of
DC 500 V.
The following figure shows the insulation resistance depending on the temperature.
4.3.2 Insulation resistance too low
NOTE
The insulation resistance varies greatly depending on the temperature, see following
figure. You can measure the insulation resistance between the connection pins and the
motor housing using an insulation measuring device.

Mechanical Installation
4.4 Installing the servomotor
4.4.1 Aligning the motor shaft
4.4.2 Use of belt pulleys/toothed belt pulleys
4.4.3 Installation in wet areas or in the open
• Try to arrange the motor and encoder connection so that the connector cables do not
point upwards.
• Coat the threads of the cable glands and filler plugs with sealing compound and tight-
en them properly. Then coat them again.
• Clean the sealing surfaces of the connector (motor and/or encoder connection) be-
fore reassembly.
• Replace any brittle seals.
• If necessary, restore the anticorrosive paint coat.
• Check the validity of the degree of protection according to the nameplate.
• If necessary, attach covers (protection canopy).
STOP!
Improper installation may result in damages to the servomotor.
Potential damage to property!
• Mount the servomotor only in the specified mounting position on a level, vibration-
free, and torsionally rigid support structure.
• Align the servomotor and the driven machine carefully to avoid placing any unac-
ceptable strain on the output shafts.
• Permitted overhung loads and axial forces (see page 50).
• Do not butt or hammer the shaft end.
NOTE
Components with a keyway to be mounted belatedly on the shaft must be balanced us-
ing a half key. Motor shafts with a keyway are balanced with a half key.
NOTE ON EXPLOSION PROTECTION
• If using belt pulleys / toothed belt pulleys:
– Only use belts that do not build up an electrostatic charge.
– Do not exceed the maximum permitted overhung load
(see page 50).
