SINUMERIK 810D Equipment Manual Configuration CCU (PHC) – 03/2006 Edition
When handling components which can be destroyed by electrostatic
discharge, it must be ensured that personnel, the workstation and
packaging are well grounded.
Generally, electronic modules must not be touched unless work has to be
carried out on them. Only touch electronic modules after you have
grounded yourself.
Touch components only if:
– you are constantly grounded via an ESD arm band,
– ESD-shoes or ESD-shoe grounding strips if there is an ESD floor.
Modules may be placed only on electrically conductive surfaces (table with
ESD top, conductive ESD foam plastic, ESD packing bags, ESD transport
containers).
Keep modules away from visual display units, monitors or TV sets
(minimum distance from screen 10 cm).
Do not bring ESD-sensitive modules into contact with chargeable and
highly-insulating materials, such as plastic, insulating table tops or clothing
made of synthetic materials.
Measurements on modules are allowed only if
– the measuring instrument is properly grounded (e.g. equipment
grounding conductor), or
– before measuring with a potential-free measuring instrument, the probe
is briefly discharged (e.g. touch the unpainted metal parts of the control
housing).
