Connection
The switch provides a grounding screw on the top panel for chassis grounding. After
crimping one end of the grounding cable to a cold pressed terminal, fix the grounding screw
and connect the other end to the earth firmly.
Note:
Cross-sectional area of the chassis grounding cable>2.5 mm
2
; grounding resistance<5Ω.
4.6 Power Terminal Block
The power terminal is located on the cover plate of the device, and the power cord is
connected to the terminal block to supply power to the device. This device supports redundant
power input and adopts 5 core 5.08 mm spacing plug-in terminal block. when any one of the
power supply failure, the device can run normally without interruption, improve the reliability
of network operation.
说明：
Power cord cross-sectional area should be above 0.75mm
2
(max cross-sectional is 2.5mm
2
)
；
grounding resistance<5
。
Copper conductor must be used for field wiring and the temperature should
meet 75
℃
.
