Installation requirements
2.2.1
Power requirements
The input voltage must be stable with neither EMI noise nor distortion.
When DC power supply is used, the input voltage is - 48 V DC and the allowed range is
−
- 40 V DC to - 72 V DC.
When AC power supply is used, the input voltage is 110/220 V AC and the allowed
−
range is 100 V DC to 240 V AC.
All safety requirements and rules about electricity of the locality or the building must be followed. All
power supply must be legal.
2.2.2
Device grounding requirements
A good grounding system is the basis for the stable and reliable operation of the device, and an
important guarantee for lightning, anti-interference and anti-static protection of the device. Users
must provide a good grounding system for the device.
2.2.3
Installation site requirements
To ensure the stable operation of the device in the long run, the installation site must meet the
following requirements:
The working environment temperature of the device should be controlled at -5°C to
−
45°C. Place the device away from the main heat source (such as power supply). If the
ambient temperature is higher than 45 °C, improve the ventilation of the room, such
as installing fans or air conditioners.
The humidity of the installation site should range from 10% to 95%, non-condensing
−
and frost-free.
