Safety information for Users
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
electrostatic discharges:
The symbol is located on the module, the module rack or on packing
material and it indicates 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 discharge 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 may 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.
Attention!
•
Before commissioning, the device has to be brought in environment
temperature.
•
With condensation you may only switch on the device after complete
dryness.
•
To prevent overheat during operation avoid direct sun contact of the
device.
•
After opening of the control cabinet or panel, parts of the system are
available that may lead dangerous voltage.
•
All signal connections require screened cables.
•
Signal cores may not be lead within a cable shaft of high-voltage cores.
•
Please take care for sufficient ground of the operating device. For this a
ground screw is to be found at the backside of the device.
