Technical data
The system data of AC500 and S500
Chapter 2.6.1 “System data AC500” on page 971
are
applicable to the standard version.
The system data of AC500-XC
Chapter 2.7.1 “System data AC500-XC” on page 1023
applicable to the XC version.
Only additional details are therefore documented below.
The technical data are also applicable to the XC version.
