Electrical Installation

Electrical connections
The MP270 requires electrical connections
to the power supply,
to the configuration computer (PU or PC),
to the PLC,
to the printer.
The electrical connections to the PU/PC is required purely for downloading the
runtime software ProTool/Pro RT and configuration data. Following the
configuration and test phases, a serial printer can be connected to the MP270
instead of the configuration computer.
EMC compatible installation
A precondition for error-free operation is an EMC compatible hardware design of
the PLC and the use of interference-proof cables. The guidelines on
interference-free design of the PLCs apply equally to installation of the MP270.
Caution
!
Only shielded cables are permitted for all signal connections.
Screw or lock all plug connections.
Do not install signal lines in the same cable ducts as power cables.
Siemens AG refuses to accept liability for malfunctions and damage arising
from use of self-made cables or cables from other manufacturers.
