Mechanical Installation
4.3.3
Installation in damp locations or outdoors
Drives are supplied in corrosion-resistant versions with a surface protection coating for
use in damp areas or outdoors. Repair any damage to the paint work (e.g. on the
breather valve or the eyebolts).
When mounting the motors onto AM, AQ adapters and to AR, AT start-up and friction
couplings, seal the flange areas with a suitable sealing compound, e.g. Loctite
®
574.
Units installed outdoors must be protected from the sun. Suitable protective devices are
required, such as covers or roofs. Avoid any heat accumulation. The operator must en-
sure that foreign objects do not impair the function of the gear unit (e.g. falling objects
or coverings).
4.3.4
Gear unit venting
The following gear units do not require venting:
•
R..07 in mounting positions M1, M2, M3, M5 and M6
•
R..17, R..27 and F..27 in mounting positions M1, M3, M5 and M6
•

W..37, W..47 gear units in mounting positions M1, M2, M3, M5 and
M6
•
K..19, K..29 gear units in mounting positions M1, M2, M3, M5 and M6
SEW-EURODRIVE supplies all other gear units with the breather valve installed and ac-
tivated according to the particular mounting position.
Exceptions:
1. SEW supplies the following gear units with a screw plug on the vent hole provided:
– Gear units with pivoted mounting positions, if possible
– Gear units for inclined mounting
The breather valve is located in the motor terminal box. Before startup, replace the
highest screw plug with the breather valve provided.
2. SEW supplies a breather valve in a plastic bag for mount-on gear units requiring
venting on the input side.
3. Enclosed gear units are supplied without a breather valve.
4. In some countries, the breather valve is installed, but not activated due to possible
pressure fluctuations during transport. In these cases, the breather valve must be ac-
tivated by removing the transport protection as described in chapter "Activating the
breather valve".
