3.2 Transportation

3.2.1 Inspection on Receipt

After receiving the delivery, immediately check whether
the scope of delivery matches the shipping documents.
Danfoss will not honour claims for faults registered later.
Register a complaint immediately:
•
With the carrier in case of visible transport
damage.
•
With the responsible Danfoss representative in
case of visible defects or incomplete delivery.
Commissioning may have to be suspended if the unit is
damaged.
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.

3.2.2 Transport

Before transporting the OneGearDrive, the eyebolt
provided must be firmly tightened down to its bearing
surface. The eyebolt can only be used to transport the
OneGearDrive unit and not for lifting attached machines.

3.3 Protection Rating

IEC 34-5/529. The drives are totally enclosed and dust-tight
as well as hose proof.
The OneGearDrive Standard is for use in aggressive areas

3.5 Mounting Arrangement

CAUTION
HIGH TORQUE AND FORCE
Depending on the reduction ratio, the OneGearDrive
develops substantially higher torques and forces than
high-speed motors of similar power.
•
•
Install the drive unit as free from vibration as possible.
Observe the special instructions for installation locations
with abnormal operating conditions (for example high
ambient temperatures >40 °C). The fresh air intake must
not be restricted by unsuitable installation or build-up of
dirt.
Use slip clutches if there is a risk of blocking.
Take care when fitting transmission elements onto the
hollow shaft of the OneGearDrive, which is finished to ISO
H7. Use the tapped end hole intended for this purpose
according to DIN 332.

Handle the OneGearDrive with care and do not
place it on any rough surfaces.
Rate the mounts, substructure and torque
restraint for the high forces anticipated during
operation. Secure them sufficiently against
loosening.
Cover the output shaft(s) and any 2nd motor
shaft extension present, as well as the
transmission elements mounted on it
(couplings, chain wheels etc.), so that they
cannot be touched.
