1.2 Structure of the safety notes
1.2.1 Meaning of signal words
The following table shows the graduation and meaning of the signal words for safety
notes, warnings regarding potential risks of damage to property, and other notes.
1.2.2 Design of the section-related safety notes
Section-related safety notes do not apply to a specific action, but to several actions per-
taining to one subject. The symbols used either indicate a general hazard or a specific
hazard.
This is the formal structure of a safety note for a specific section:
1.2.3 Design of the embedded safety notes
Embedded safety notes are directly integrated into the instructions just before the de-
scription of the dangerous action.
This is the formal structure of an embedded safety note:
•SIGNAL WORD! Type and source of hazard.
Possible consequence(s) if disregarded.
– Measure(s) to prevent the hazard.
Signal word Meaning Consequences if disregarded
DANGER! Imminent hazard Severe or fatal injuries
WARNING! Possible dangerous situation Severe or fatal injuries
CAUTION! Possible dangerous situation Minor injuries
NOTICE Possible damage to property Damage to the drive system or its envi-
ronment
NOTE Useful information or tip: Simpli-
fies handling of the drive sys-
tem.
SIGNAL WORD!
Type and source of danger.
Possible consequence(s) if disregarded.
• Measure(s) to prevent the danger.

caused by live, bare (in the event of open connectors/terminal boxes) and movable or
rotating parts.
Risk of burns caused by hot surfaces
Severe or fatal injuries
• All work related to transport, storage, installation, assembly, connection, startup,
maintenance and repair may only be carried out by qualified personnel.
• For transport, storage, installation, assembly, connection, startup, maintenance
and repair it is important that you adhere to the information in the following docu-
ments:
– Warning and safety signs on the motor/gearmotor
– All the project planning documents, startup instructions and wiring diagrams re-
lated to the drive
– System-specific regulations and requirements
– National/regional regulations governing the safety and prevention of accidents

Safety Notes
2.3 Target group
Any mechanical work may only be performed by adequately qualified personnel. Quali-
fied personnel in the context of this documentation are persons familiar with the design,
mechanical installation, troubleshooting and servicing of the product who possess the
following qualifications:
• Training in mechanical engineering, e.g. as a mechanic or mechatronics technician
(final examinations must have been passed).
• They are familiar with these operating instructions.
Any electronic work may only be performed by adequately qualified electricians. Quali-
fied electricians in the context of this documentation are persons familiar with electrical
installation, startup, troubleshooting and servicing of the product who possess the
following qualifications:
• Training in electrical engineering, e.g. as an electrician, electronics or mechatronics
technician (final examinations must have been passed).
• 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 unit series R..7, F..7, K..7, K..9, S..7, SPIROPLAN®W is intended for use in
industrial systems.
The gear units may only be used according to the specifications in the technical docu-
mentation from SEW-EURODRIVE as well as the specifications on the nameplate. They
fulfill the applicable standards and regulations.
When installed in machines, startup (i.e. start of designated operation) is prohibited until
it is determined that the machine complies with the local laws and directives. In the in-
dividual area of application, you must especially observe the Machinery Directive
2006/42/EC as well as the EMC Directive 2004/108/EC. The EMC test specifications
EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-6 and EN 61000-6-2 form
the basis for this.
Use in potentially explosive atmospheres is prohibited unless specifically designated
otherwise.
2.5 Other applicable documentation
The following publications and documents have to be observed as well:
• "DR.71 – 225, 315 AC Motors" operating instructions for gearmotors
• Operating instructions of any attached options
• "Gear Units" catalog or

Transport/storage
Safety Notes
2.6 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 in the event of damage.
It may be necessary to preclude startup.
Tighten the eyebolts securely. They are designed to carry only 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.
2.7 Setup
Observe the notes in the "Mechanical Installation" section.
2.8 Startup/operation
Check the oil level before startup as described in chapter Inspection/Maintenance
(page 85).
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".
NOTICE
Danger due to static overdetermination if gear units with foot (e.g. KA19/29B,
KA127/157B or FA127/157B) are mounted both via the torque arm and via the foot
plate.
Risk of injuries and damage to property.
• Especially with the KA.9B/T variant, it is not permitted to use the foot plates and the
torque arm at the same time.
• The KA.9B/T variant may only be mounted via torque arms.
• K.9 or KA.9B variants may only be mounted via the foot plate.
• If you want to use foot plates and torque arms for mounting, consult with SEW-EU-
RODRIVE.

Installation requirements
Mechanical Installation
4.2 Installation requirements
Make sure that the following requirements are met before you start installing the unit:
• The drive has not been damaged during transportation or storage.
• The entries on the nameplate of the gearmotor match the voltage supply system.
• When the unit is installed in abrasive ambient conditions, protect the output end oil
seals against wear.
• The output shafts and flange surfaces must be completely free from anti-corrosion
agents, contamination or similar. Use a commercially available solvent for cleaning.
Do not expose the sealing lips of the oil seals to the solvent – damage to the material.
•For standard drives:
– Ambient temperature according to the technical documentation, nameplate and
lubricant table in section "Lubricants".
– No harmful oils, acids, gases, vapors, radiation etc. in the vicinity
•For special designs:
– The drive is designed in accordance with the ambient conditions. Observe the in-
formation on the nameplate.
•For helical-worm/SPIROPLAN®W gear units:
– No large external mass moments of inertia which could exert a retrodriving load
on the gear unit.
– Self-locking with η’ (retrodriving) < 0.5;
Calculation : η’ = 2 – 1/η
•For servomotor mounting:
– Do not assemble the drive without having ensured that there will be sufficient ven-
tilation after installation to prevent heat build-up.
CAUTION
Risk of injury due to protruding gear unit parts.
Minor injuries.
• Keep a sufficient safety distance to the gear unit/gearmotor.
NOTICE
Damage to the gear unit/gearmotor due to improper installation.
Possible damage to property
• Strictly adhere to the notes in this chapter.
