Wiring Requirements

 

Be  sure  to  disconnect  the  power  cord  before  installing  and/or 

wiring your Ethernet Switch. 

Calculate the maximum possible current in each power wire and 

common  wire.  Observe  all  electrical  codes  dictating  the 

maximum  current  allowable  for  each  wire  size.  If  the  current 

goes above the maximum ratings, the wiring could overheat may 

causing serious damage to your equipment. You should also pay 

attention to the following items: 

1.  Use  separate  path  to  route  wiring  for  power  and  devices.  If 

power  wiring  and  device  wiring  paths  must  cross,  make  sure 

the wires are perpendicular at the intersection point. 

2.  NOTE:  Do  not  run  signal  or  communications  wiring  and 

power wiring in the same wire conduit. To avoid interference, 

wires  with  different  signal  characteristics  should  be  routed 

separately. 

3.  You  can use the type of signal transmitted through a wire to 

determine  which  wires  should  be  kept  separate.  The  rule  of 

thumb  is  that  wiring  that  shares  similar  electrical 

characteristics can be bundled together. 

4. Keep input and output wiring separated. It is strongly advised
