• When using an I/O Connecting Cable with a locking connector, be sure that the connector is
firmly locked in place before using it.
• Always turn OFF the power supply to the Controller before connecting a cable.
• An I/O bus check error will occur and the Controller will stop if an I/O Connecting Cable's con-
nector is disconnected from the Rack. Be sure that the connectors are secure.
• A 63-mm hole will be required if the I/O Connecting Cable must pass through a hole when con-
necting an Expansion Rack.
• Do not bend the I/O Connecting cable past its natural bending radius or pull in it with excessive
force.
• The cables can withstand a pulling force up to 49 N (11 lbs).
• The minimum bending radius is shown in the following diagram.
• Always attach the cover to the output connector (left side) on the last I/O Interface Unit on the
last Expansion Rack to protect it from dust.
