5.5.1 Cable installation
The cable is installed in the cable duct beneath the MCU and through the small cable
pass-through element in the connection area of the Compact Station (see Section 3.4).
The cables must be fully installed and fixed inside and outside the Compact Station. Then
the cable pass-through element must be fitted as described in Section 5.1.
5.5.2 Status signaling contact - X411
The status signaling contact is used for remote monitoring of the Compact Station. The
status of the Compact Station (mains connected or disconnected) can be established
using the potential-free relay contact. This function is adjustable, see Section 6.3.3.
