6.1 Nameplate
Danfoss geared motors are supplied with a corrosion-proof
nameplate as standard. The standard nameplate is made of
special plastic tried and tested in many years of practical
use and approved for hazardous areas by the Physikalisch-
Technische-Bundesanstalt (PTB).

6.2 Storage
If the VLT
®
OneGearDrive is being stored for an extended
time before start-up, increased protection against damage
by corrosion or humidity can be achieved by observing the
following information. The actual load depends very
strongly on local conditions, therefore the time period
stated is only a guide value. Note that this period does not
include any extension of the warranty. If disassembly is
necessary before start-up, contact Danfoss Service. The
instructions contained in this document must be observed.
Check the factory-fitted plugs in all entry holes on the
terminal box for damage caused during transportation and
for correct positioning. Replace if necessary.
Repair any damage to the exterior paint layer or to the
rust protection of the bright metal shafts, including hollow
shafts.
The storage space should be dry, well-ventilated and
vibration-free. If the temperature in the space exceeds the
normal range of -20
°
C to +40
°
C for an extended period
of time or varies strongly frequently, employ the measures
before start-up specified in 3.1 Measures before Commis-
sioning , even after short storage times.
It is recommended that the drive units be turned 180
°
every 12 months so that the lubricant in the gear unit
covers the bearings and gearwheels which have previously
been positioned on top. Also, the output shaft should be
turned manually in order to churn the rolling-contact
bearing grease and distribute it evenly.
Turning the drive unit does not have to be carried out if
the gear unit enclosure is completely filled with lubricant
as the result of a special agreement. In this case, the
lubricant level before start-up is to be reduced to the
desired value as defined in the operating instructions and
the nameplate.
