Line start permanent magnet motor (LSPM)
Compressors equipped with a line start permanent
magnet motor (LSPM) can be identified by the letter "L"
added to the type designation (e. g. 6CTEU-50LK or
4JTC-10LK). The built-in permanent magnets generate
a non-negligible magnetic field which, however, is shiel-
ded by the compressor housing.

ent magnet motor
Safety signs attached to the compressor
WARNING
Strong magnetic field!
Keep magnetic and magnetizable objects away
from compressor!
Persons with cardiac pacemakers, implanted
heart defibrillators or metallic implants: maintain
a clearance of at least 30 cm!
Work on a compressor with LSPM motor
Any work on the compressor may only be performed by
persons that are not part of the specified group. Main-
tenance work beyond the work described in the present
document and in the Operating Instructions KB-104
may only be performed after consultation with BITZER.
