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
"
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.
