Permissible humidity Mean value per year ≤ 75 % relative humidity;
on 56 days of the year up to 93 % relative humidity; con-
densation must be avoided!
Siemens recommends that all devices be installed such that they are not exposed to direct sunlight, nor
subject to large fluctuations in temperature that may cause condensation to occur.
The device is designed for installation in normal relay rooms and plants, so that electromagnetic compatibility
(EMC) is ensured if installation is done properly.
In addition, the following is recommended:
• All contacts 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
conductive shield grounded at both ends. For substations with lower operating voltages, no special mea-
sures 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 standards
(for Electrostatic Sensitive Devices) must be observed. They are not endangered when inserted into the
case.
