Max. connectable cross-section: 1.5 mm
Type: Screw terminal 1 (see Spring-Loaded Terminals/Screw Terminals)
Note
The Smart Line Module signals ready-to-operate, even though one of the external
conductors is not available. In this case the feedback is deactivated and a warning message
is output to X21/2 (DO, Warning I*t). If the feedback was deactivated by applying a "High"
signal to terminal X22/2 (DI, Disable), no warning message will be output to X21/2 (DO,
Warning I*t).
Note
For operation, 24 V DC must be connected to terminal 3 and ground to terminal 4. When
removed, pulse inhibit is activated, feedback is deactivated and the bypass relay drops out. If
the Line Module is not disconnected from the line supply when the EP terminal is deactivated
(e.g. a main contactor is not installed), the DC link remains charged.
NOTICE
If a drive line-up is switched off by means of the line disconnecting device, the voltage at
terminals 3 (EP +24 V) and 4 (EP M) must be interrupted beforehand. This can be carried
out using a leading breaking auxiliary contact (≥ 10 ms), for example.
This protects external loads located parallel to the drive on the same switching component.

•
DC link is pre-charged
•
Pulses enabled (X21.3/.4)
•
No overtemperature
•
No overcurrent switch-off
•
DO: Prewarning
High = no prewarning
Low = prewarning
Overtemperature warning threshold / I*t
•
No regenerative feedback capability due to a line fault
