5.1 Important notes
¯ The mounting site must always comply with the operating conditions stated in
the technical data. Take additional measures if necessary.
¯ The mechanical connections must always be ensured.
¯ The mounting rail and the mounting plate in the control cabinet must be
electrically conductive and free of lacquer.
¯ Attach and detach Controllers and modules of the I/O system 1000 only when the
supply voltage is switched off. Otherwise, they could be damaged by short
circuits.
¯ Always arrange the modules from left to right starting with the Controller directly
followed by a power supply module EMP−S701 on the right side.
¯ The module must always be installed directly next to each other. Free slots
between the modules are not permissible because otherwise the backplane bus
would be interrupted.
¯ The side contacts of the last module always must be covered with the supplied
contact cover. Otherwise, the modules may be damaged by short circuit or static
discharge.
