ƒ Carry out the electrical installation according to the relevant regulations (like cable

cross−sections, fusing, connection to the PE conductor). Additional notes can be

found in the detailed operating instructions.

ƒ For the connection, the following has to be observed:

– A safe PE connection has to be established,

– The specified clearances between bare live parts among each other and against

earth must be observed.

For the motor connection, the use of Lenze system cables is recommended.

( Stop!

ƒ Tighten the coupling ring of the connector.

ƒ If plugs without SpeedTec bayonet nut connectors are used, the connector

boxes for the power / encoder / fan connections must be secured by

O−rings if loadings by vibration occur:

– M17 connector box with O−ring 15 x 1.3 mm

– M23 connector box with O−ring 18 x 1.5 mm

– M40 connector box with O−ring 27 x 4.0 mm
