This pictogram is used in relation to Danger, Warning, and Caution notices.
1.4 Proper Usage
• The instrument or instrument components may only be used for the applications described in the
manual or the technical description, and only in combination with the equipment, components,
and devices of other manufacturers as far as this is recommended or permitted by Heraeus
Electro-Nite.
• The instrument described has been developed, manufactured, tested, and the manual compiled in
keeping with the relevant safety standards. Consequently, if the handling instructions and safety
guidelines described for planning, installation, operation, and maintenance are adhered to, the
instrument, under normal conditions, will not be a source of danger to property or life.
1.5 Procedures for Maintenance and Repair
If measurement or testing work is to be carried out on an active unit, your national accident prevention
rules and regulations must be observed. Use only suitable electrical tools.
Warning:
• Repairs to an item of automation equipment may only be carried out by Heraeus Elec-
tro-Nite service personnel. For replacement purposes, use only parts or components
contained in the spare parts list or listed in the Spare Parts List section of this manual.
Unauthorised opening of equipment and improper repairs can result in loss of life or se-
vere personal injury as well as substantial property damage.
• Only use the fuse types specified in the technical specifications or the maintenance
instructions of this manual.
• Do not throw batteries into an open fire and do not carry out any soldering work on
batteries (danger of explosion). Maximum ambient temperature 85C. Lithium batteries
or batteries containing mercury should not be opened or recharged. Make sure that the
same type is used when replacing batteries.
• Batteries must be disposed of as classified waste.
1.6 Guidelines for Handling Electrostatic Discharge
VLSI chips (MOS technology) are used in practically all Heraeus Electro-Nite electronic modules.
These VLSI components are, by their nature, very sensitive to over voltages and thus to electrostatic
discharge (ESD).
1.6.1 Electrostatic Discharge
This pictogram and warning label is used on cabinets, sub-racks, and packing and suggests
that modules are susceptible to ESD.
Before starting maintenance or installation make sure that you have sufficient protection
against ESD.
Electronic devices can be destroyed by voltage and energy levels that are far below the level
perceptible to human beings. Such voltages can occur when a component or a module is touched by
a person who has not been electrostatically discharged.
In most cases, the components subjected to such over voltages, cannot be immediately detected as
faulty; the fault occurs only after a long period in operation.
1.6.2 Shipping of ESD-Sensitive Modules
Anti-static packing material must always be used when storing and dispatching modules and
components. If the container itself is not conductive, the modules must be wrapped in a conductive
