Wiring
Ground before disconnecting the grounding wire after power off.
The upper cover of the device has a ground screw (see fig.2), that is, the ground wire of the chassis, called
"chassis ground". Connect one end of the ground wire
After being crimped with the cold-pressed terminal, fix it at the "chassis ground" with a grounding screw, and the
other end of the grounding wire is reliably connected to the ground.
Note:
Cross-sectional area of ground wire 2.5 mm2Above; grounding resistance requirements: <5 Om.
4.4 Power terminal
The power terminal is located on the upper cover of the device, and the power cable is connected to the
device through the power terminal to supply power to the device. This series of equipment supports redundant
power source input, using 4 pin 5.08mmSpacing plug-in terminals, when any one of the power supply fails, the
equipment can be with uninterrupted normal operation, the reliability of network operation is improved.
