Storing The Gear Unit; Standard Preservation - Siemens Flender H2NV Series Assembly And Operating Instructions Manual

4.3

Storing the gear unit

The gear unit must be stored in a sheltered place, placed on a vibration­free, dry base, and covered over.
When temporarily storing the gear unit and any single components supplied with it, the
preservative agent should be left on them. It must not be damaged, otherwise there is
a risk of corrosion.
Do not stack gear units on top of one another.
If the gear unit is being stored out of doors, it must be particularly carefully covered,
and care must be taken that neither moisture nor foreign material can collect on the
unit. Waterlogging should be avoided.
During storage the gear units must not be opened under any circumstances.
All openings on the gear unit (such as oil filling and/or aerating and ventilating
openings) must be kept closed until start­up.
Unless otherwise agreed by contract, the gear units must not be exposed to harmful
environmental factors such as chemical products, high air pollution, high air humidity and
ambient temperatures outside the range from 0 to + 40 °C.
Provision for special environmental conditions during transport (e.g. transport by ship) and
storage (climate, termites, etc.) must be contractually agreed.
4.4

Standard preservation

The gear unit is provided with an interior preservative agent; the free shaft ends are painted for protection.
The characteristics of the external coat depend on the ambient conditions stipulated in the order relating
to method of transport and area of application.
The gear unit is normally delivered completely ready, with a priming and a finish coat.
The coating complies with the requirements for the conductivity of the coating and the
limitation of the layer thickness of the applied coating in accordance with
DIN EN 13463­1. The permissible maximum coating thickness depends on the
indicated explosion group (IIA or IIB or IIC). Where lacquer coatings have a thickness
less than 200 μm, no electrostatic charge is to be expected.
Where gear units are delivered with a priming coat only it is necessary to apply a finish
coat in accordance with the directives applying to the specific case of application.
The priming coat alone is not suitable to provide a sufficient long­term corrosion
protection.
The coating must not carry an electrostatic charge!
The operator must ensure that highly effective mechanisms which can set up a charge
in the coating are safely avoided.
Examples of highly effective charge­generating mechanisms are:
– the rapid passage of heavily dust­laden air near by
– the sudden escape of particle­laden compressed gases
– other heavy friction action (not manual cleaning or rubbing with cleaning cloths)
