Service Conditions
The protective device is designed for use in an industrial environment and an electrical utility environment.
Proper installation procedures should be followed to ensure electromagnetic compatibility (EMC).
In addition, the following is recommended:
•
All contacts and relays that operate in the same cubicle, cabinet, or relay panel as the numerical protec-
tive device should, as a rule, be equipped with suitable surge suppression components.
•
For substations with operating voltages of 100 kV and above, all external cables should be shielded with
a conductive shield grounded at both ends. For substations with lower operating voltages, no special
measures are normally required.
•
Do not withdraw or insert individual modules or boards while the protective device is energized. In with-
drawn condition, some components are electrostatically endangered; during handling the ESD stand-
ards (for Electrostatic Sensitive Devices) must be observed. They are not endangered when inserted into
the case.
