2.10.1 Transport and storage
• Only pack, store, transport and ship electronic components, modules or devices in the
original product packaging or in other suitable materials, e.g. conductive foam rubber or
aluminum foil.
• Observe the limits during transport and storage. See Technical specifications (Page 130)
section.
2.10.2 Installation and connection
• We recommend touching components, modules and devices only if they are grounded by
one of the following measures:
– With an ESD wrist strap.
– With ESD shoes or ESD grounding strips in ESD areas with conductive flooring.
• Place electronic components, modules and devices only on conductive surfaces (e.g.
tables with ESD coating, conductive ESD plastic foam, ESD packing bags, ESD transport
containers).
• Ensure that there is sufficient overvoltage protection.
Installation/disassembly with voltage switched on
• Refer to the Mounting (Page 52) section
• Read the Replacing modules (Page 122) section.
• Observe the special conditions for hazardous areas in the section AUTOHOTSPOT.
