Plug connectors
(
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
Plug−in connectors (plug/connector box) with SpeedTec bayonet nut
connectors are vibration−proof.
ƒ
If SpeedTec bayonet nut connectors are used, O−rings must be removed (if
any)!
ƒ
Never disconnect plugs when voltage is being applied! Otherwise, the plugs
could be destroyed! Inhibit the controller before disconnecting the plugs!
