1.4.3.1 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.

or for internal connection of process voltages
Earthing Direct connection to the earthed DIN rail or via
the screws with wall mounting
Screw terminals Front terminal, conductor connection vertically
with respect to the printed circuit board
Spring terminals Front terminal, conductor connection vertically
with respect to the printed circuit board
Weight 200 g
Mounting position Horizontal or vertical
Terminal Units (AC500 Standard) > TU515, TU516, TU516-H and TU542 for I/O Modules
