Permissible humidity
Mean value per year
≤
75 % relative humidity; on
56 days of the year up to 93 % relative humidity;
condensation must be avoided!
Siemens recommends that all devices be installed such that they are not exposed to direct sun-
light, nor subject to large fluctuations in temperature that may cause condensation to occur.
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
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 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 In withdrawn condition, some components are electrostatically endangered; during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 EEC standards (standards for Electrostatically Endangered Components) must
be observed. They are not endangered when inserted into the case.
