11 Retrofitting Interfaces - JUMO mTRON T Operating Manual

This section describes how to retrofit the modules for optional interfaces RS232 and RS422/
485 of central processing unit 705001.
CAUTION!
Incorrect handling may result in damage or malfunctions.
This compromises the function of the central processing unit or the system as a whole.
Only qualified personnel are permitted to carry out module retrofits. Existing country-specific
requirements for changes at an electrical device have to be observed. Before a retrofit, the
system must be shut down and disconnected from the power supply.
CAUTION!
Modules may be damaged by electrostatic discharge.
This compromises the function of the central processing unit or the system as a whole.
Modules may only be retrofitted at a grounded workstation and in compliance with the rele-
vant safety measures.
Identifying the module
The module can be identified using the part no. on the packaging.
