4.1.8 Deployment Conditions
4.1.9 Constructive versions
The protection device is designed for installation in normal relay rooms and plants, so that electromagnetic immunity is
ensured if installation is done properly.
In addition the following is recommended:
• Contacts and relays operating within the same cabinet or on the same relay board with digital protection equipment,
should be in principle provided with suitable surge suppression components.
• For substations with operating voltages of 100 kV and above, all external cables shall be shielded with a conductive
shield earthed at both ends. For substations with lower operating voltages, no special measures are normally required.
• For substations with lower operating voltages, no special measures are normally required. When removed, many com-
ponents are electrostatically endangered; when handling the EEC standards (standards for Electrostatically Endan-
gered Components) must be observed. The modules, boards, and device are not endangered when the device is com-
pletely assembled.
