State LEDs
In case of overload or short-circuit, the outputs switch off automatically and try to switch on
again cyclically. Therefore, an acknowledgement of the outputs is not necessary.

Technical Data
The System Data of AC500 and S500
Ä
Chapter 2.6.1 “System Data AC500” on page 1248 are
valid for standard version.
The System Data of AC500-XC
Ä
Chapter 2.7.1 “System Data AC500-XC” on page 1309 are
valid for the XC version.
Only additional details are therefore documented below.
