Active Line Module X24 24 V Terminal Adapter - Siemens SINUMERIK 840D sl Manual

Connection of the Components
5.3 Line Modules Interfaces Description
Warning
For operation, ground must be attached to the -X21:3 24 VDC terminals and the -X21:4
terminals. For cancelation, a pulse suppression will be activated. Feedback is deactivated
and the bypass relay drops out. If the Line Module is not separated from the supply system
when the EP terminal is opened (e.g. no main power switch present), the DC link will remain
charged.
Notice
If the main power switch is used to switch off a running drive group, the voltage at terminal 3
(EP +24 V) and 4 (EP M) must be interrupted beforehand. This can be achieved, for
example, with a leading (≥10 ms) disconnecting auxiliary contact.
