If you keep the prescribed environmental conditions (see technical data) the corre-
sponding safety module is maintenance-free.
Please only use original spare parts of YASKAWA.
WARNING!
Incorrect or faulty spare parts can cause damage, malfunction or failure
as well as affect security.
For shipping always use the original packaging.
National rules and regulations apply to the disposal of the unit!
VIPA modules make use of highly integrated components in MOS-Technology. These
components are extremely sensitive to over-voltages that can occur during electrostatic
discharges. The following symbol is attached to modules that can be destroyed by elec-
trostatic discharges.
The Symbol is located on the module, the module rack or on packing material and it indi-
cates the presence of electrostatic sensitive equipment. It is possible that electrostatic
sensitive equipment is destroyed by energies and voltages that are far less than the
human threshold of perception. These voltages can occur where persons do not dis-
charge themselves before handling electrostatic sensitive modules and they can damage
components thereby, causing the module to become inoperable or unusable. Modules
that have been damaged by electrostatic discharges can fail after a temperature change,
mechanical shock or changes in the electrical load. Only the consequent implementation
of protection devices and meticulous attention to the applicable rules and regulations for
handling the respective equipment can prevent failures of electrostatic sensitive modules.
When you are conducting measurements on electrostatic sensitive modules you should
take the following precautions:
n
Floating instruments must be discharged before use.
n
Instruments must be grounded.
CAUTION!
Personnel and instruments should be grounded when working on electro-
static sensitive modules.
