The subsequently described installation and assembly operations only
refer to the FM 458-1 DP, EXM 438-1 and EXM 448/EXM 448-2
modules, which can be installed in the S7-400 automation system.
Detailed information about the mechanical design of a SIMATIC S7-400
station, as well as the installation which must be observed when
locating modules in the PLC, are provided in the "S7-400 Installation
Manual" (C79000-G7000-C417).
Proceed as follows to install the FM 458-1 DP module (also as module
assembly with options) into the subrack of an S7-400:
1. Remove the line connector at the power supply module.
2. Remove the dummy covers from the slots in which you wish to insert
the modules. Hold the dummy cover at the positions marked and
withdraw towards the front.
3. Insert the module (1) and carefully swing it downwards (2). If you
detect some resistance when swinging the module downwards,
slightly lift the module and try again.
