Surface treatment
(continued)
Colors
In addition to anthracite gray (RAL 7016), you can select from
other standard colors.
You can find additional colors in our
SIMOGEAR Configurator
electronic catalog.
Note
For light colors in corrosivity category C1 we recommend selec-
tion of surface treatment in the corrosivity category one level
higher to ensure adequate and uniform coloring for the geared
motor.
■
Preservation
All gearboxes and geared motors are preserved as standard
for 6 months.
Long-term preservation up to 36 months
If the gearboxes are stored for longer than 6 months, then
we recommend the "Long-term preservation" option. A VCI cor-
rosion inhibitor (volatile corrosion inhibitor) is added to the gear-
box oil.
Until commissioning, it is not permissible that the gearbox is
opened, as otherwise the VCI corrosion inhibitor will vaporize.
The oil level must be checked before commissioning. Corrosion
protection is also applied to the flange contact surfaces and
shaft extensions. We recommend that the gearbox is stored
in the appropriate mounting position.
Storage conditions
Geared motors, stored in dry, dust free and evenly tempered
rooms do not require any special packaging.
In all other areas, the units must be packaged in foil with desic-
cant and moisture indicator. If required, protection must be pro-
vided against mold and termites. The storage location must be
vibration- and shock-free. The storage conditions must be
regularly checked.
For information about storage and commissioning please refer to
the operating instructions.
