Inrush current
(1) A label has been placed over the upper surface of the SYSMAC LINK Unit
to prevent wire cuttings from entering the Unit. When wiring the backup
power supply, leave the label in place.
(2) When wiring is complete, remove the label to avoid overheating.
(3) Use a power supply that is not connected to PLC operation, as in the case
of the node bypass function, for the backup power supply so that when
the power to the PLC is turned OFF, the backup power supply will contin-
ue.
(4) Use a dedicated power supply for the backup power supply. Do not share
a power supply being used for I/O, motors, or control systems.
(5) When two or more nodes are connected to a single backup power supply,
wire each node separately.

Backup power
supply
Unlike the CV500-SLK11, the CS1W-SLK11 does not require an Auxiliary
Power Supply Unit for the node bypass function. Instead, directly connect a
24-VDC external power source as a backup power supply.
Attach crimp terminals to the power supply cable when connecting the backup
power supply to the SYSMAC LINK Unit.
Crimp Terminals
Use an M3 crimp terminal, as illustrated below.
6.2 mm max.
Specification
200 mA max. at 24 V DC (per node)
