Transport/storage
Safety Notes
2.5 Transport/storage
Inspect the shipment for any damage that may have occurred in transit as soon as you
receive the delivery. Inform the shipping company immediately. It may be necessary to
preclude startup.
Tighten the eyebolts securely. They are designed to only carry the weight of the
motor/gearmotor; do not attach any additional loads.
The built-in lifting eyebolts comply with DIN 580. Always observe the loads and regula-
tions listed in this standard. If the gearmotor is equipped with two eyebolts, then both
should be used for transportation. In this case, the tension force vector of the slings must
not exceed a 45° angle according to DIN 580.
Use suitable, sufficiently rated handling equipment if required. Reattach these in the
case of further transportation.
Store the motor/gearmotor in a dry, dust-free environment if it is not to be installed
straight away. You must not store the motor/gearmotor outdoors or on the fan guard.
The motor/gearmotor can be stored for up to 9 months without requiring any special
measures before startup.
2.6 Installation
Make sure that the supports are even, the foot and flange mounting is correct and if
there is direct coupling, align with precision. Resonances between the rotational
frequency and the double network frequency caused by the structure are to be avoided.
Release the brake (if installed), turn rotor manually, check for unusual grinding noise.
Check the direction of rotation in decoupled status.
Only install or remove belt pulleys and couplings using suitable devices (heat up) and
cover with a touch guard. Avoid improper belt tension.
Make the pipe connections that may eventually be required. Mounting positions with
shaft ends pointing upwards should be equipped with a cover to prevent foreign objects
from falling into the fan. Ensure that ventilation openings are not obstructed and that
used air, including air from adjacent units, cannot be drawn in again straight away.
Observe the notes in the "Mechanical Installation" section.
2.7 Electrical connection
2.7.1 Brakemotor
All work may only be carried out by qualified personnel. During work, the low-voltage
machine must be at standstill, de-energized, and safeguarded against accidental
restart. This also applies to auxiliary circuits (e.g. anti-condensation heating or forced
cooling fan).
Check whether the motor is de-energized!
Exceeding the tolerances in EN 60034-1 (VDE 0530, part 1) – voltage + 5%, frequency
+ 2%, curve shape, symmetry – increases the heating and influences electromagnetic
compatibility. Also comply with EN 50110 (where necessary, observe other applicable
national regulations, such as DIN VDE 0105 for Germany).
Observe the wiring information and any differing data on the nameplate as well as the
wiring diagram in the terminal box.
The connection must be a permanently secure electrical connection (no protruding wire
ends); use the cable end equipment intended for this purpose. Establish a secure

protective earth connection. When the motor is connected, the distances to non-insu-
lated and live parts must not be shorter than the minimum values according to IEC
60664 and national regulations. With low voltage, the distances should be no shorter
than the following values, in compliance with IEC 60664:
The terminal box must be free from foreign objects, dirt and humidity. Unused cable
entry openings and the box itself must be closed so that they are dust- and water-proof.
Secure the key for test mode without output elements. When operating low-voltage
machines with brakes, check that the brake is functioning correctly before startup.
Observe the notes in the "Electrical Installation" chapter.
2.8 Startup/operation
Whenever changes to normal operation occur, such as increased temperatures, noise,
vibrations, etc., try to determine the cause. Consult the manufacturer if required. Never
deactivate protection devices, even in test mode. Switch off the motor in case of doubt.
Regularly clean air ducts in dusty or dirty environments.
2.8.1 Surface temperature during operation
Servomotors/brakemotors get very hot during operation.
Touching the servomotor/brakemotor can result in burns if it has not cooled down. The
servomotor can have a surface temperature of more than 100 °C during operation.
Never touch the servomotor/brakemotor during operation or during the cool-down phase
once it has been switched off.

• Removal tool for insulator for changing the connector.
4.3 Long-term storage of servomotors
Observe the following notes when you take a stored motor into operation:
• The service life of the ball bearing grease is reduced after storage periods exceeding
one year.
• SEW-EURODRIVE recommends to have the motor inspected by SEW Service after
4 years in storage to check the ball bearing grease for signs of ageing.
• 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 insulation resistance varies greatly depending on the temperature. You
can measure the insulation resistance between the connection pins and the
motor housing using an insulation measuring device. The motor must be dried
