CAUTION
Danger due to static overdetermination in the case of gearmotors when the gear unit
is attached to the foot plate (e.g. KA19/29B, KA127/157B or FA127/157B, R gear
unit with foot-mounted motor) and the motor is attached to the foot plate as well.
Risk of injuries and damage to property
•
Attach only the gear unit or only the motor to the foot plate.
NOTICE
Damage to gear unit/gearmotor due to cold air currents. Condensed water in the
gear unit can cause damage.
Damage to property
•
Protect the gear unit from direct cold air currents.
INFORMATION
When installing the gear unit, make sure that the oil level and drain plugs as well as
the breather valves are easily accessible!
Mounting position
The gear unit or gearmotor is only allowed to be installed in the specified mounting po-
sition. Observe the information on the nameplate. SPIROPLAN
®
gear units of sizes
W10 – W30 are mounting position-independent.
Oil fill quantity
Check the oil fill depending on the mounting position (for information on the fill quantity
refer to the nameplate). Control the oil fill level at this opportunity. See chapter
spection/maintenance for the gear unit" (→
). The gear units are filled with the
required oil quantity at the factory. There may be slight deviations at the oil level plug
as a result of the mounting position, which are permitted within the manufacturing tol-
erances.
Changing the
mounting position
Adjust the lubricant fill quantities and the position of the breather valve accord-
ingly in the event of a change of mounting position.
Also observe chapter "
INFORMATION
Do not change the mounting position without prior consultation with
SEW‑EURODRIVE.
The information on the nameplate is binding. The ATEX EU declaration of conformity
and the guarantee no longer apply if the mounting position is changed without prior
consultation with SEW‑EURODRIVE. Changes to the mounting position must be pro-
jected and indicated on the nameplate.
Submounting
The support structure must have the following characteristics:
•
Level
•
Vibration damping
•
Torsionally rigid
The following table shows the maximally permitted flatness defect for foot- and flange-
mounting (guide values based on DIN ISO 1101):
