Installing The Terminal Module For Power Supply Ps - Siemens SIMATIC ET 200iSP Operating Instructions Manual

Installing the mounting rail
1. Mount the rail in the cabinet so that you have sufficient space for installation and heat
dissipation of the modules (maintain the minimum clearance to the casing).
2. If necessary, mark the mounting holes on the base of the enclosure and drill the holes with
a diameter of 6.5 mm
3. Screw the mounting rail to the base surface of the cabinet (screw size M6).
Note
Make sure there is a low-resistance connection between the mounting rail and the base of
the cabinet.
If the ET 200iSP is subjected to increased vibration and shock loads, we recommend screwing
the mounting rail to the mounting surface centrally between the two outer fixing holes (at
b/2). The securing screws require an additional M6 hole at b/2 on the mounting rail (see table
above).
