12.2 Check Before Powering On For The First Time - Siemens SIMATIC S7-1500 System Manual

12.2 Check before powering on for the first time
Before the first power-on, check the installation and the wiring of the S7-1500R/H redundant
system.
Questions for checking
The following questions provide instructions for checking your system in the form of a
checklist.
Rack
• Are the rails firmly mounted to the wall, in the frame, or in the cabinet?
• Are the cable ducts correctly installed?
• Have the minimum clearances been observed?
Grounding concept
• Are the rails connected to the protective conductors?
• If applicable, are all further protective conductor connection points on the S7-1500R/H
redundant system connected to the protective conductor? Has the protective conductor
been tested?
• Are the required equipotential bonding cables connected with low impedance to the
relevant sections of the plant?
Module installation and wiring
• Are all the modules inserted/installed in accordance with the installation schedule and
STEP 7 configuration, and screwed firmly to the rails?
• Have all synchronization modules been installed and locked in the S7-1500H redundant
system? You should hear the modules click into place in the module slots.
• Are all redundancy connection connectors in the S7-1500H redundant system correctly
connected to the LC sockets? You should hear the connectors click into place in the LC
sockets.
• Are the redundancy connections (PROFINET cable) between the CPUs in the S7-1500R
redundant system connected to the correct ports of PROFINET interface X1? The ports
used must correspond to the configuration in STEP 7.
• Are the PROFINET devices in the S7-1500R/H redundant system connected?
System power/load current supply
• Are all system power/load current supplies switched off?
• Is the power cable connector correctly wired?
