8.3 Safety information for wiring
NOTICE
The module can be damaged if power is connected when wiring the NCU
When connecting the NCU, the system and the NCU must be disconnected (brought into a no
voltage condition).
Note
If your axis grouping contains a Smart Line Module without DRIVE-CLiQ (5 kW or 10 kW), you
must assign the Smart Line Module enabling signal to digital input X122.1 on the NCU.
8.4 Opening the front cover
Introduction
The interfaces are concealed behind a front cover. You must fold down this cover before you can
wire up the interfaces. When the front cover is closed (ipped up), it automatically locks into
place by means of a hook on the connector panel.
Note
Replacement of the front cover in the event of servicing
A hinge connects the front cover to the front of the housing. In order to replace it, it can easily
be removed in the open state (45° angle) by pulling it slightly. It is installed in the same way, at
a 45° angle, by slightly pressing on the hinge.
