Electromagnetic Compatibility - Siemens SIMOTICS XP 1LA5 Compact Operating Instructions

Closed bearings
● For sealed 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 Siemens Service Center, or technically coordinate
•
outdoors use.

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.
