Design
The protection device is designed for installation in normal relay rooms and plants, so that electromagnetic compati-
bility (EMC) is ensured if installation is done properly.
In addition, the following are recommended:
• All contactors and relays that operate in the same cubicle, cabinet, or relay panel as the numerical 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 conduc-
tive shield earthed at both ends. For substations with lower operating voltages, no special measures are normally
required.
• Do not withdraw or insert individual modules while the protective device is energized. In withdrawn condition, some
components are electrostatically endangered; during handling the ESD standards (for
E

S
ensitive

e-
vices) must be observed. The modules and device are not endangered when inserted into the housing.
