Technical Data
4.1 General
Humidity
Admissible humidity
It is recommended that all devices be installed so that they are not exposed to direct sunlight nor subject to large fluctu-
ations in temperature that may cause condensation to occur.

Deployment Conditions

4.1.8
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 equip-
ment, 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
components are electrostatically endangered; when handling the EEC standards (standards for Electrostatically
Endangered Components) must be observed. The modules, boards, and device are not endangered when the
device is completely assembled.
