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 nu-
merical protective 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 oper-
ating voltages, no special measures are normally required.
• Do not withdraw or insert individual modules or boards while the protective device is ener-
gized. In withdrawn condition, some components are electrostatically endangered; during
handling the ESD standards (for Electrostatic Sensitive Devices) must be observed. They
are not endangered when inserted into the case.
