Installation of toroidal cores
h The three phases without shielding and without PE must be lead through the cores.
The cores must be installed and attached near the motor connection of the BM5500,
BM5600, BM5700 .
h When
using toroidal cores it is further recommended to use current isolated bearings
on the nondrive end for synchronous/asynchronous main drives sizes 180 and higher.

7.9 Requirements for the motor temperature sensors
Type Additional requirements: Isolation
KTY84/PT1000 - SELV/PELV
MSKL
1)
(PTC) R = 1 k at T
threshold
, I
max
< 2 mA SELV/PELV
To protect the motor against not permitted over
heating, a motor temperature sensor can
be connected to the b maXX device. The device switches off of the motor when a settable
threshold temperature has been exceeded.
1)
Motor protection resistor (PTC) as per DIN 44080-082
NOTE!
The motor temperature sensor should be installed in such a manner that „safe elec-
trical separation“ is ensured. The motor temperature sensors integrated into
Baumüller motors meet these requirements. If third-party motors are connected, the
proprietor must ensure that the temperature sensors used in the motor of a third-party
manufacturer motor comply with the „safe electrical separation“ function.
