10.2 Important notes
CAUTION
The choke can become hot during operation (rising to temperatures in
excess of 80° C). Risk of light burns and fire! Therefore, you should make
sure that the choke is mounted a sufficient distance away from neigh-
bored components. Provide the requisite conditions for unobstructed con-
vection to cool the choke.
You must read the instructions manual for the servo amplifier/servo motor you are using in
your application and observe the safety instructions they contain before commencing mount-
ing/installation work. This manual is only valid in conjunction with the instructions manual for
the servo amplifier and servo motor you are using in your application.
Mount the motor choke 3YLN on a conductive earthed assembly plate in the switchgear cab-
inet. The choke box 3YL-24 can be mounted to DIN rails as well.
The motor choke is wired into the cable close to the amplifier. When laying the motor cable,
allow about 400 mm for the connection to the choke.
