Conditions of the gear unit and storage area for long-term storage prior to commissioning:
• Store the gear unit at a temperature in the range of -5 °C to +40 °C without severe temperature
fluctuations.
• Check if the sealing cord in the vent screw is in place. It must not be removed during storage.
• Store the gear unit in a dry space. With a relative humidity less than 60%, the gear unit can be
stored for up to two years; with a relative humidity less than 50%, storage of up to three years is
possible.
• For gear units, which are filled with VCI concentrate for long-term storage, the VCI concentrate
must be renewed after 2 years and distributed in the oil by rotating the shaft.
• In tropical regions, protect the gear unit against damage by insects.
• Gear unit components such as brakes, couplings, belt drive, and cooling units must be protected
for a long-term storage in accordance to their operation instructions.
In addition to the preparations listed in 4 "Commissioning", the following measures are necessary
before commissioning:
• Check the gear unit for external damage.
• After storage of more than 2 years, or with storage temperatures outside of the permissible range
from -5 °C to +40 °C, replace the lubricant in the gear unit before commissioning.
• If the gear unit is completely filled, the oil level must be reduced according to the mounting position.
For the lubricant quantity and lubricant type, refer to the information on the name plate.
• For gear units without oil filling, the oil level must be refilled and checked according to chapter 5.2.5
"Oil level" before commissioning. The VCI concentrate may remain in the gear unit. The VCI
concentrate is not mixable with polyglycol-based lubricants (PG oils). If PG oils are used, the VCI
concentrate must be removed from the gear unit. When using VCI additive, only use the oil types
which are specified on the name plate and are approved by Getriebebau NORD (see chapter 7.3.2
"Gear oils").
• For Option VL/KL2 to VL6/KL6, replace the bearing grease after a storage time of more than
2 years. The service life of the grease is reduced after a storage time or gearbox shutdown of more
than 9 months (see chapter 5.2.15 "Re-lubricating the bearing in the output flange (Option:
VL2/3/4/6, KL2/3/4/6)").
• Gear units filled with VCI concentrate for long-term storage are fully closed. Take care that the vent
is fitted and released as necessary prior to commissioning. The installation position can be
obtained from the specific dimension sheet for the order.
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.
