NOTICE
Electrostatic discharge
The CPU contains components that can be damaged or destroyed by electro-
static discharge.
− When handling the CPU, observe the necessary safety measures against
electrostatic discharge (ESD) in accordance with
EN 61340-5-1 and
IEC 61340-5-1.
The modules are equipped with highly integrated components in MOS technology. These
components are highly sensitive to over-voltages that occur
, e.g. with electrostatic dis-
charge. The following symbol is used to identify these hazardous modules:
The symbol is located on modules, module racks or on packaging and thus indicates
electrostatic sensitive modules. Electrostatic sensitive modules can be destroyed by ener-
gies and voltages that are far below the limits of human perception. If a person who is
not electrically discharged handles electrostatic sensitive modules, voltages can occur
and damage components and thus impair the functionality of the modules or render the
modules unusable. Modules damaged in this way are in most cases not immediately rec-
ognized as faulty
. The error can only appear after a long period of operation. Components
damaged by static discharge can show temporary faults when exposed to temperature
changes, vibrations or load changes. Only the consistent use of protective devices and
responsible observance of the handling rules can effectively prevent malfunctions and
failures on electrostatic sensitive modules.
Please always use the original packaging for shipping.
NOTICE
Material damage due to non-observance of ESD instructions
If you do not follow the ESD instructions when unpacking and packing,
damage to the CPU may occur
.
− Please note the ESD instructions when unpacking and packing the CPU.
For measurements on electrostatic sensitive modules the following must be observed:
■ Floating measuring instruments must be discharged before use.
■ Measuring instruments used must be grounded.
When modifying electrostatic sensitive modules, ensure that a grounded soldering iron is
used.
CAUTION
When working with and on electrostatic sensitive modules, make sure that
personnel and equipment are adequately grounded.
