XG33, on, off, ZKS (DC bus short circuit) status
View
Connec‐
tion
I/O
Function
1
I
Supply voltage of inputs/outputs (24VEA*)
2
O
Supply voltage for external, current sourcing output
(ZKS1*)
Output (24VEA) is used to connect input XG33.3
3
I
DC bus short-circuit input for signaling an active DC
bus short circuit (ZKS2*)
Not connected:
ZKS active
Connected to 24VEA of XG33.2:
ZKS not active
The mains contactor opens in the case of an active
DC bus short circuit.
4
O
Supply voltage for external OFF output (OFF1*)
Output (24VEA) is used to connect input XG33.5
5
I
OFF input (OFF2*)
Connection for N/C contact to switch off the supply
unit
The input is always available, irrespective of wheth‐
er or not a master communication has been activa‐
ted. Compared to the master communication, the
input is of higher priority. The input can be used, for
example, to loop in an emergency stop circuit or the
like.
6
O
Supply voltage for external ON output (ON1*)
Output (24VEA) is used to connect input XG33.7
7
I
ON input (ON2*)
Connection for N/O contact to switch on the supply
unit.
The input is edge-controlled.
The input is only available, if the master communi‐
cation has been deactivated (P-0-4089.0.1).
8
I
Reference potential of supply voltage (0VEA*)

Function, pin assignment
Operating HNA05 with HMU05 (slave mode) requires at least the
OFF input and the DC bus short circuit input (ZKS) to be connec‐
ted.
