(for example, Megger) between all winding parts and
between the winding and the enclosure.

5.1.3 Gear Unit Component
•
Oil
Change the oil in the gear unit if the storage
period exceeds five years or the temperatures
were harsh throughout a shorter storage period.
For detailed instructions and oil recommen-
dations, see
•
Shaft seals
Lubricate the hollow shaft seal with grease if the
storage period exceeds two years. When
changing the oil, the function of the shaft seals
between the motor and gear unit as well as on
the output shaft must also be checked. The shaft
seals must be replaced if any change in shape,
color, hardness or sealing effect is detected.
5.2 Commissioning Procedure
1.
Remove the protective films.
2.
Disconnect the mechanical connection to the
machine being driven as far as possible and
examine the direction of rotation in the no-load
state.
3.
Remove the feather keys or secure them in such
a way that they cannot be ejected.
4.
Ensure that the current draw in the loaded
condition does not exceed the rated current
indicated on the nameplate for any length of
time.
5.
After first commissioning, observe the
OneGearDrive for at least hour hour to detect any
unusual heat or noise.
