STORE AND TRANSPORT THE DEVICE WITH FACTORY PACKAGING.
Humidity 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 sunlight, nor subject to large fluctuations in temperature that may cause conden-
sation to occur.
10.1.8 Service Conditions
The protective device is designed for use in an industrial environment and an electrical
utility environment. Proper installation procedures should be followed to ensure elec-
tromagnetic compatibility (EMC). 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 conductive shield grounded at both ends. The shield must
be capable of carrying the fault currents that could occur. For substations with lower
operating voltages, no special measures are normally required.
