quirements set forth in Directive 2014/34/EU and comply with the applicable standards
and regulations.
The gear units are components for the installation in machines and plants according to
the 2006/42/EC Machinery Directive. Within the scope of the Directive, you must not
operate the machine in the designated fashion until you have established that the end
product complies with Machinery Directive 2006/42/EC.
Optional equipment

ance with German operating safety regulations (BetrSichV) or other national regula-
tions must be observed for connecting additional devices:

plate and in the documentation; they have to be observed under all circumstances.
2.5 Other applicable documentation
Observe the corresponding documentation for all further components.
2.6 Safety note for working in potentially explosive areas
Note that explosive gas mixtures or concentrations of dust can lead to explosions in
conjunction with hot, live, or moving parts of electrical machinery.
2.7 Transportation/storage
Inspect the shipment for damage as soon as you receive the delivery. Inform the ship-
ping company immediately about any damage. If the product is damaged, it must not
be assembled, installed or started up.
Observe the storage information on climatic conditions as given in chapter "Storage
conditions"(→2174).
If the product is not immediately installed, it must be stored in a dry and dust-free loca-
tion. The product can be stored for up to 9 months without requiring any special meas-
ures before startup. Do not store the product outdoors.
The permissible storage temperature is -30°C to +50°C.
For storage periods longer than 9 months, SEW‑EURODRIVE recommends the "Ex-
tended storage" design. For further information, refer to chapter "Extended stor-
age"(→2174).
The installed lifting eyebolts are in accordance with DIN580. Observe the loads and
regulations specified there. The tension force vector of the slings must not exceed a
45° angle in accordance with DIN580.
If the product has several lifting eyes or lifting eyebolts, then you should use all lifting
eyes and lifting eyebolts for attaching transport ropes. Tighten lifting eyebolts. The lift-
ing eyes or lifting eyebolts are designed to carry only the weight of the product. Do not
apply any additional loads.
The gear units K..167 and K..187 have no lifting eyes and are supplied without lifting
eyebolts. Use alternative, suitable slings.
Do not store the gearmotor on the fan guard.
Use suitable, sufficiently rated and reusable handling equipment.

2.8 Installation/assembly
Ensure that the product is installed and cooled according to the regulations in the doc-
umentation.
Protect the product from strong mechanical strain. The product and its mounting parts
must never protrude into the path of persons or vehicles. Ensure that components are
not deformed, particularly during transportation and handling. Electric components
must not be mechanically damaged or destroyed.
The following applications are prohibited unless the device is explicitly designed for
such use:
• Operation in applications with impermissibly high mechanical vibration and shock
loads in excess of the regulations stipulated in EN61800-5-1
• Use in environments with harmful oils, acids, gases, vapors, dust, radiation, etc.
Observe the danger due to static overdetermination. Gear units with foot (e.g.
KA19/29B, KA127/157B or FA127/157B) must not be fastened via the torque arm and
the foot plate at the same time. Gearmotors must also not be fastened to the foot plate
of the gear unit (e.g. KA19/29B, KA127/157B or FA127/157B, R gear unit with foot-
mounted motor) and the foot plate of the motor at the same time.
2.9 Startup/operation
Check the oil level before startup as described in chapter "Inspection/mainten-
ance"(→2107).
Check that the direction of rotation is correct in the decoupled state. Listen out for un-
usual grinding noises as the shaft rotates.
Secure the keys for the test run without output elements.
Do not deactivate monitoring and protection devices even for a test run.
Switch off the gearmotor if in doubt whenever changes occur in relation to normal
operation (e.g. increased temperatures, unusual noises, vibrations). Determine the
cause. It may be necessary to contact SEW‑EURODRIVE.
2.10 Inspection/maintenance
Observe the information in chapter "Inspection/maintenance"(→2107).
