Environmental Conditions
Ambient Temperature
The ambient temperature refers to the temperature of the air immediately surrounding the device.
-
Operation temperature:
-
–25 to +70 °C (–13 to +158 °F): Normal operating temperature
-
–35 to –25 °C (–31 to –13 °F): Commissioning possible
-
-
Storage temperature: –50 to +85 °C (–58 to +185 °F)
Extreme Atmospheric Conditions
TeSys GV5 / GV6 devices are designed to operate in industrial atmospheres as defined in IEC/EN 60947-2 standard for the highest level of pollution (level 3).
They are tested for extreme storage conditions according to the following standards:
|
Standard |
Title |
|---|---|
|
IEC/EN 60068-2-2 |
Dry heat, severity level +85 °C (+185 °F) |
|
IEC/EN 60068-2-1 |
Dry cold, severity level –50 °C (–58 °F) |
|
IEC/EN 60068-2-30 |
Damp heat, cyclic
|
|
IEC/EN 60068-2-52 |
Salt-mist test |
It is recommended to install the device in a properly ventilated switchboard without excessive dust.
Vibration
Conformity tests are carried out in accordance with IEC/EN 60068-2-6 standard at the levels of severity required by the merchant shipping regulatory body (DNV-GL):
-
2 Hz to 13.2 Hz with an amplitude of +/- 1 mm (+/- 0.04 in)
-
13.2 Hz to 100 Hz at a constant acceleration of 0.7 g
Electromagnetic Disturbances
Overcurrent protection tests are carried out in accordance with the electromagnetic compatibility (EMC) standard (IEC/EN 60947-2 standard appendixes F and J).
Check for compliance with EMC standard by testing for immunity to:
-
Overvoltages produced by the operation of electromagnetic switchgear.
-
Overvoltages produced by atmospheric disturbance that pass through the electrical network (for example, lightning).
-
The use of apparatus emitting radio waves (such as radio transmitters, walkie-talkies, or radar).
-
Electrostatic discharges produced by the operators themselves.
Conformity with EMC standard as described above helps to ensure that:
-
The device operates correctly in a disturbed environment:
-
Without nuisance tripping.
-
In accordance with the trip time.
-
-
There is no disturbance to any type of industrial or commercial environment.
