Storing indoors
The storage rooms must provide protection against extreme weather conditions. They must be dry, free from dust, frost and
vibration and well ventilated.
Bare metal surfaces
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be coated with an anti-corrosion agent
which will last for a limited amount of time (<6 months). Apply suitable anti-corrosion measures for longer storage times.
Condensation drain hole
Open any condensation drain holes to drain the condensation depending on the environmental conditions, every six months
at the latest.
Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For machines that have a special design regarding the ambient temperature in the operating state or the installation altitude,
other conditions could apply regarding the storage temperature. In this case, refer to the machine rating plate for data on the
ambient temperature and installation altitude.
Storage time
Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce the useful life of the bearing
grease (aging).
Open bearings
● For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12 months.
● Replace the grease if it is identified that the grease has lost its lubricating properties or is polluted. The consistency of the
grease will change if condensation is allowed to enter.
Closed bearings
● For closed bearings, replace the DE and NDE bearings after a storage time of 48 months.
NOTICE
Storage
The motor can be damaged if you use it or store it unprotected outdoors.
•
Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a superstructure or additional cover,
for example.
•
If required, contact the service center, or technically coordinate outdoors use.
4.5 Electromagnetic compatibility
Note
If the torque levels are very unequal (e.g. when a reciprocating compressor is being driven), a non-sinusoidal machine
current will be induced whose harmonics can have an impermissible effect on the supply system and cause impermissible
interference emissions as a result.
Note
Converter
• If operated with a frequency converter, the emitted interference varies in strength, depending on the design of the
converter (type, interference suppression measures, manufacturer).
•
Avoid that the specified limit values stipulated for the drive system (consisting of the motor and converter) are exceeded.
• You must observe the EMC information from the manufacturer of the converter.
•
The most effective method of shielding is to conductively connect a shielded machine supply cable to the metal terminal
box of the machine (with a metal screw connection) over a large surface area.
• On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages caused by the converter may occur on
the sensor cable.
