Safety Notes
2 Safety Notes
The following basic safety notes must be read carefully to prevent injury to persons and
damage to property. The operator must ensure that the basic safety notes are read and
observed. Make sure that persons responsible for the plant and its operation, as well as
persons who work independently on the unit, have read through the operating instruc-
tions carefully and understood them. If you are unclear about any of the information in
this documentation, or if you require further information, please contact SEW-
EURODRIVE.
2.1 Preliminary information
The following safety notes are primarily concerned with the use of explosion-proof gear
units. If using gearmotors, also refer to the safety notes for motors in the corresponding
documentation.
Also observe the supplementary safety notes in the individual sections of this documen-
tation.
2.2 General information
Removing covers without authorization, improper use as well as incorrect installation or
operation may result in severe injuries to persons or damage to property.
Refer to the documentation for additional information.
WARNING
During operation, the motors and gearmotors can have live, bare and movable or ro-
tating parts as well as hot surfaces, depending on their enclosure.
Explosive gas mixtures or concentrations of dust can lead to severe or fatal injuries in
conjunction with hot, live and moving parts of electrical machinery.
Severe or fatal injuries.
• All work related to transportation, storage, setup/mounting, connection, startup,
maintenance and repair may only be carried out by qualified personnel, in strict ob-
servance of:
– The relevant detailed operating instructions
– The warning and safety signs on the motor/gearmotor
– All other project planning documents, operating instructions and wiring dia-
grams related to the drive
– The specific regulations and requirements for the system
– The national/regional regulations governing safety and the prevention of acci-
dents
• Never install damaged products
• Immediately report any damage to the shipping company

• They are familiar with these operating instructions.
All work in further areas of transportation, storage, operation and waste disposal must
only be carried out by persons who are trained appropriately.
All qualified personnel must wear appropriate protective clothing.
2.4 Designated use
The gear units are intended for industrial systems and may only be used in accordance
with the information provided in SEW-EURODRIVE's technical documentation and the
information given on the nameplate. They fulfill the applicable standards and regula-
tions.
According to the 2006/42/EC Machinery Directive, the gear units are components for the
installation in machines and plants. In the scope of the Directive, you must not take the
machinery into operation in the proper fashion until you have established that the end
product complies with Machinery Directive 2006/42/EC.
NOTE ON EXPLOSION PROTECTION
A drive motor connected to the gear unit may only be operated under the conditions
described in the "Startup" section (page 42).
Operate any gear unit connected to the motor on the frequency inverter only if the data
on the gear unit nameplate is met!
If a gear unit is operated in combination with a variable speed gear unit, the operating
instructions of the variable speed gear unit must be handled separately.
A motor mounted to a gear unit by means of an adapter or belt may only be operated
if the data on the gear unit nameplate is met!
There may be no aggressive substances in the vicinity that could damage the paint
and seals.

Safety Notes
2.6 Transport
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 installed eyebolts. They are designed to only carry the weight of the motor/gear-
motor; do not attach any additional loads.
The built-in lifting eyebolts meet DIN 580. Always observe the loads and regulations
listed in this standard. If the gearmotor is equipped with 2 suspension eye lugs or lifting
eyebolts, then both of the suspension eye lugs 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 necessary. Remove any transpor-
tation fixtures prior to startup.
2.7 Installation/assembly
Observe the notes in chapter "Mechanical Installation" (page 20).
2.8 Startup/operation
Check the oil level before startup as described in chapter "Inspection/Maintenance".
Check that the direction of rotation is correct in decoupled status. Listen out for unusual
grinding noises as the shaft rotates.
Secure keys for test mode without output elements. Do not deactivate monitoring and
protection equipment even in test mode.
Switch off the gearmotor if in doubt whenever changes occur in relation to normal oper-
ation (e.g. increased temperature, noise, vibration). Determine the cause and contact
SEW-EURODRIVE, if required.
2.9 Inspection/maintenance
Observe the notes in chapter "Inspection/Maintenance" (page 44).

Checklist
3 Checklist
3.1 Before startup
This checklist includes all activities that will have to be performed prior to startup of a
gear unit according to Directive 94/9/EC for operation in potentially explosive atmo-
spheres.
3.2 During startup
This checklist includes all activities that will have to be executed during startup of a gear
unit according to Directive 94/9/EC for operation in potentially explosive atmospheres.
Check prior to startup in potentially explosive atmospheres Checked Information
in section ...
Inspect the shipment for any damage that may have occurred in transit as soon as you receive the delivery.
Inform the shipping company immediately. Startup may have to be precluded. Remove transportation safety
fixtures prior to startup.
2.6
Does the following information on the gear unit nameplate correspond with the permitted conditions for
potentially explosive atmospheres on site:
• Equipment group
• ATEX category
• ATEX zone
• Temperature class
• Maximum surface temperature
4.3, 5.3 + 5.7
Have arrangements been made to prevent explosive atmospheres, oils, acids, gases, vapors or radiation
during installation of the gear unit?
5.2
Is the ambient temperature maintained according to the lubricant table? 9.1
Have arrangements been made for sufficient ventilation and that there will be no external heat generation
(e.g. via clutches)? The cooling air may not exceed a temperature of 40 °C.
5.4 + 5.3
Does the mounting position on the gear unit nameplate correspond to the indicated mounting position?
Important: The mounting position may only be changed after consultation with SEW-EURODRIVE. ATEX
approval will become void without prior consultation.
5.4 + 8
Are all oil check and drain plugs as well as breather plugs and valves freely accessible? 5.4
Do all input and output elements to be installed have ATEX certification? 5.7
Have you checked that the data on the nameplate of the gear unit are not exceeded for standalone gear
units with adapter or input shaft assembly?
6.2 + 7.3 +
4.3
For mains-operated motors:
• Check that the data specified on the nameplate of the gear unit and the motor corresponds to the ambi-
ent conditions at the location where the drive is to be installed.
4.3 + 6.3
For inverter-operated gearmotors: Check that the gearmotor is approved for operation with an inverter
• The parameter settings made for the inverter must prevent the gear unit from being overloaded (→gear
unit nameplate).
4.3 + 6
Check during startup in potentially explosive atmospheres Checked Information
in section ...
Measure the surface temperature after three hours of operation. Do not exceed a temperature difference of
55 K compared to the ambient temperature. If the value is > 55 K, stop the drive immediately and contact
SEW-EURODRIVE!
6.2
Measure the oil temperature. Add 10 K to the measured value. Determine lubricant change interval using
this value.

4.3.5 Information on the special indication
NOTE ON EXPLOSION PROTECTION
In some cases SEW gear units/gearmotors must only be operated in compliance with
special measures. For these cases, there is a special indication on the nameplate
