Interface description

8.4.3.1

X3 DC link connection

Table 8- 18 X3: Connection for the DC link
Connection/Meaning
C/L+ input (plus DC link)
D/L- input (minus DC link)
Protective conductor
Shield connection
Connection via
AWG
Note
After the DC link voltage is applied, fault output -X38/5 is "low" for approx. 2 seconds (self-
test), i.e. in the "fault" state. The Control Unit must suppress this state when the system is
switched on.
