10.1.7 Climatic Stress Tests
Ambient
Temperatures
Standards: IEC 60255–6
– recommended operating temperature –5 °C to +55 °C (+23 °F to +131 °F)
if max. half of the inputs and outputs are subjected
to the max. permissible values
– recommended operating temperature –5 °C to +40 °C (+23 °F to +104 °F)
if all inputs and outputs are subjected
to the max. permissible values
– limiting temporary (transient) –20 °C to +70 °C
operating temperature (–4 °F to 158 °F)
in quiescent state, i.e. no pick-up and no
indications
– limiting temperature during storage –25 °C to +55 °C (–13 °F to 131 °F)
– limiting temperature during transport –25 °C to +70 °C (–13 °F to 158 °F)
Storage and transport of the device with factory packaging!
Humidity Permissible humidity mean value p. year ≤75 % relative humidity
on 56 days per year up to 93 % relative
humidity; condensation not permissible!
It is recommended that all devices are installed such that they are not exposed to di-
rect sunlight, nor subject to large fluctuations in temperature that may cause conden-
sation to occur.
10.1.8 Service Conditions
The device is designed for use in an industrial environment or an electrical utility en-
vironment, for installation in standard relay rooms and compartments so that proper
installation and electromagnetic compatibility (EMC) is ensured. In addition, the follow-
ing 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.
Visibility of display
may be impaired
above +55 °C/130 °F
