3.2 Storage
Under favourable conditions, the drive can be stored for several years.
• If necessary, treat the unprotected, finished surfaces (e.g. flange surface, shaft end) with corrosion
protection agents.
• Store the drive in a dry, dust-free space.
• The drive must not be exposed to vibration or oscillation.
Measures before commissioning
• Inspect the drive before commissioning.
• If the storage time has exceeded 4 years under the above mentioned conditions, replace the roller
bearings. If stored under unfavourable conditions, the roller bearings must be replaced earlier.
• Check the insulation resistance of the winding (please see chapter 4.2 "Check insulation
resistance" on page 30).
3.3 Preparing for installation
3.3.1 Check for damages
Please examine the delivery for transport and packaging damage immediately on receipt. Pay
particular attention to radial shaft seals and sealing caps. Report any damage to the carrier
immediately.
Do not put the drive into operation if damage such as leaks are visible.
3.3.2 Remove corrosion protection agents
All bare metal surfaces and shafts of the drive are protected with corrosion protection agents before
shipping.
Thoroughly remove corrosion protection agents and any dirt (e.g. colour residues) from all shafts,
flange surfaces and gear unit attachment surfaces before assembly.
3.3.3 Check rotational direction
If an incorrect rotational direction may result in damage or potential risk, check for the correct
rotational direction of the output shaft during a test run before attaching it to the machine. Ensure the
correct rotational direction during operation.
3.3.4 Check ambient conditions
Ensure that the drive is suited for the installation location with regard to requirements prescribed by
standards, ambient conditions and the installation height.
3.3.5 Drives with nsd tupH surface treatment
Drives with
nsd tupH
surface treatment must be electrically decoupled from other components by the
use of non-conductive intermediate layers in order to prevent galvanic corrosion.
