Mounting to a PC Section 3-5
3-5-2 Mounting to a CJ-series PC
Ethernet Units can be connected to either a CJ-series CPU Rack or a CJ-
series Expansion CPU Rack. Connect the Ethernet Unit in any of the posi-
tions shown below using the sliders on the top and bottom of the Unit. Up to
four Ethernet Units can be mounted to a single PC. If it is mounted in combi-
nation with other CPU Bus Units (e.g., Controller Link Units), the maximum
total number of CPU Bus Units that can be mounted is 16.
Note Tighten PC Backplane mounting screws to a torque of 1.2 N
⋅m, and the Unit’s
screws to a torque of 0.8 N
â‹…m.
Note The CS1W-ETN01/ETN11 Ethernet Unit’s maximum current consumption is
380 mA. Make sure that the total current consumption of all the Units con-
nected to the same CPU Backplane or Expansion Backplane does not exceed
the output capacity of the Power Supply Unit.
