must be connected to the correct port on a DC power supply device 

otherwise, the ZXSDR R8881 S4200 may be damaged.  

 

4.2.2

 

Connecting

 

the

 

Grounding

 

Wire

   

1. Connect one end of the grounding wire to the GND port at the bottom of the ZXSDR 
R8881 S4200.   
2. Connect the other end of the grounding wire to the nearest outdoor grounding busbar.   

Note:

 

When

 

you

 

connect

 

cables,

 

you

 

should

 

connect

 

the

 

grounding

 

wire

 

first

 

and

 

the

 

power

 

cable

 

last.

 

And

 

when

 

you

 

disconnect

 

cables,

 

you

 

should

 

disconnect

 

the

 

power

 

cable

 

first

 

and

 

the

 

grounding

 

wire

 

last.

   

 

3. If the ODCPD1 is used, use one grounding wire to connect the GND port of 
ZXSDR R8881 S4200 to the grounding point of the ODCPD1, and then use 
another grounding wire to connect the grounding point of the ODCPD1/PIMAC to the 
nearest outdoor grounding busbar.
