5.3 Location Requirements
The P631 has been designed to conform to EN 60255-6. Therefore it is important
when choosing the installation location to make certain that it provides the
operating conditions as specified in above DIN norm sections 3.2 to 3.4. Several
of these important operating conditions are listed below.
5.3.1 Environmental Conditions
Ambient temperature: -5 °C to +55 °C [+23 °F to +131 °F]
Air pressure: 800 to 1100 hPa
Relative humidity: The relative humidity must not result in the formation of
either condensed water or ice in the P631.
Ambient air: The ambient air must not be significantly polluted by dust,
smoke, gases or vapors, or salt.
Solar Radiation: Direct solar radiation on the front of the device must be
avoided to ensure that the LC-Display remains readable.
5.3.2 Mechanical Conditions
Vibration stress: 10 to 60 Hz, 0.035 mm and 60 to 150 Hz, 0.5 g
Earth quake resistance: 5 ... 8 Hz, 3.5 mm / 1.5 mm, 8 ... 35 Hz, 5 m/s²,
3 x 1 cycle
5.3.3 Electrical Conditions for Auxiliary Voltage of the Power Supply
Operating range: 0.8 to 1.1 V
A,nom
with a residual ripple of up to 12 % V
A,nom
5.3.4 Electromagnetic Conditions
Substation secondary system design must follow the best of modern practices,
especially with respect to grounding and EMC.
