Storage in rooms and protection against humidity

The motors can be stored for up to two years under the following conditions:
Storing indoors
● Apply a preservation agent (e.g. Tectyl) to bare external components if this has not
already been carried out in the factory.
● Store the motors as described in Section "Ambient conditions for long-term storage".
The storage room/area must satisfy the following conditions:
– Dry
– Dust-free
– Free of any vibration
– Well ventilated
– Protected against extreme weather conditions
– The air inside the room or space must be free of any aggressive gases
● Protect the motor against shocks and humidity.
● Make sure that the motor is covered properly.
Protection against humidity
If a dry storage area is not available, then take the following precautions:
● Wrap the motor in humidity-absorbent material. Then wrap it in foil so that it is air tight.
● Include several bags of desiccant in the sealed packaging. Check the desiccant and
replace it as required.
● Place a humidity meter in the sealed packaging to indicate the level of air humidity inside
it.
● Inspect the motor on a regular basis.
