NOTICE
Improper installation and assembly can damage the gear unit.
Possible damage to property.
•
Observe the following notes.
•
Before releasing shaft connections, make sure that there are no active torsional
moments present (tensions within the system).
•
Make sure that the customer components are designed for the load.
•
The most important technical data is provided on the nameplate.
Additional data relevant for operation is available in drawings, on the order con-
firmation or in an order-specific documentation.
•
Do not change the mounting position without prior consultation with
SEW‑EURODRIVE. The warranty will become void without prior consultation.
•
Do not modify the gear unit or the mount-on components without prior consultation
of SEW-EURODRIVE.
•
Protect rotating drive parts, such as couplings, gear wheels, or belt drives using
suitable devices that protect from contact.
•
Install/mount the gear unit only in the specified mounting position on a level, vibra-
tion-damping, and torsionally rigid support structure. Do not twist housing legs and
mounting flanges against each other.
•
Make sure that the oil level and oil drain plugs, as well as the breather plugs are
freely accessible.
•
When installing a filter in the cooling unit, make sure there is sufficient height for
removing the filter element and the filter hood.
•
Use plastic inserts if there is a risk of electrochemical corrosion between the gear
unit and the driven machine (connection between different metals such as cast
iron and high-grade steel). Install the bolts also with plastic washers. Always
ground the gear unit housing.
•
Only authorized personnel may assemble gear head units with motors and ad-
apters. Consult SEW-EURODRIVE.
•
Do not weld anywhere on the drive. Do not use the drive as a ground point for
welding work. Welding may destroy gearing parts and bearings.
•
Units installed outdoors must be protected from the sun. Install suitable protective
devices, such as covers or roofs. Avoid heat from building up. The user must en-
sure that foreign objects do not impair the function of the gear unit (e.g. falling ob-
jects or coverings).
•
Protect the gear unit from direct cold air currents. Condensation may cause water
to accumulate in the oil.
•
Gear units are supplied with a suitable painting for use in damp areas or in the
open air. Repair any damage to the paint work (e.g. on the breather).
•
Do not modify the existing piping.
•
For gear units that are filled with oil at the factory, check to see that the breather
plug is installed before you start up the gear unit.
•
Observe the safety notes in the individual chapters.
