5.3 Direct installation
Mount the dedicated power supply by tightening M4 screws to the upper and
lower mounting holes (two holes in all) provided in the dedicated power supply.
6. Construction Cautions
Installation of dedicated power supply
At least one dedicated power supply is required per CC-Link/LT system.
When constructing the system using only one dedicated power supply, the
following three conditions should be satisfied.
If the following four conditions are not satisfied, use two or more dedicated power
supplies or power adapters (CL1PAD1) in constructing the system.
• The current capacity of the dedicated power supply is 2A or less, therefore, total
current consumption should be an equivalent to or less than 2 A.
• Total current at start-up of each module + current consumption of the I/O
equipment that receives power from a dedicated power supply ≤ Maximum
output current (2.2A) of dedicated power supply
• In order to operate a stable system, the voltage drop should be equivalent to or
less than 3.6 V.
• The minimum operating voltage of each module is 20.4 V, therefore, supply voltage
subtracted by the voltage drop should be equivalent to or more than 20.4 V.
6.1 System power calculation method
6.1.1 Current consumption calculation
*1 Some remote I/O modules for CC-Link/LT supply the power for I/O via the
connection cable.
For the details, refer to the instruction manual of each remote I/O module.
6.1.2 Voltage drop
Calculate the voltage drop based on the simplified graph or the calculation
formula. (supply voltage: 24V DC, ambient temperature: 20°C)

*1 Some remote I/O modules for CC-Link/LT supply the power for I/O via the
connection cable.
For the details, refer to the instruction manual of each remote I/O module.
The simplified graph and the calculation formula concerning voltage drop
calculations may not be accurate depending on the ambient temperature
and the number of used connectors dedicated to CC-Link/LT.
If the driving voltage (20.4V) cannot be assured in a used remote I/O
module, add another dedicated power supply or power adapter (CL1PAD1).
6.1.3 Start-up current calculation
Construct the system properly so that the calculated start-up current (when the
power is turned on) does not exceed the maximum output current (2.2 A) of the
dedicated power supply.
