4.3 Component dimensions
Length of the profile rails
The following profile rails are available.
Table 4-1 Profile rails - Overview
Profile rail length usable length for modules Order No.
160 mm 120 mm ES7 390-1AB60-0AA0
482.6 mm 450 mm ES7 390-1AE80-0AA0
530 mm 480 mm ES7 390-1AF30-0AA0
830 mm 780 mm ES7 390-1AJ30-0AA0
2,000 mm cut to length if required ES7 390-1BC00-0AA0
In contrast to other profile rails, the 2-meter rail is not equipped with any fixing
holes. These must be drilled, allowing optimal adaptation of the 2-meter profile rail
to your application.

• Module height: 125 mm
• Module height with shielding terminal module: 185 mm
• Maximum mounting depth: 130 mm
• Maximum mounting depth of CPU 31xC, including the plugged DP connector
with chamfered cable guide: 140 mm
• Maximum mounting depth with open hinged front panel (CPU): 180 mm
Dimensions of other modules such as CPs, FMs etc. are found in the respective
manuals.
Shielding terminal module
If you use a shielding terminal module, the dimension specifications apply from the
lower edge of the module.
The direct contact of the shielding terminal module to the profile rail makes it easy
for you to connect all shielded cables of S7 modules to ground.
