SIMATIC 545/555/575 System Manual
Installing 575 System Hardware
To install the Series 505 remote I/O annex card (PPX:575–2126), follow the
steps below.
1. Carefully set your CPU board on a static-dissipative surface.
CAUTION
Electronic equipment can be damaged by electrostatic discharge.
Ensure that personnel make contact with a static-dissipative pad and/or wear a
grounded wrist strap when handling the CPU cards or modules.
2. Lower the annex card directly onto the CPU board as shown in
Figure 4-16, applying pressure until all connectors and standoffs are
mated.
NOTE: If you are installing the annex card on a 575–2104, ensure that
dipswitch settings are correct before you mate the annex card to the CPU
board, because the dipswitch is inaccessible once the annex card is installed.
