4-3 Wiring the Terminals
This section describes how to wire the terminals on the CIF Units.
Be sure that all terminal screws and cabl
e connector screws are tightened to the torque specified in the
relevant manuals. The loose screws may result in fire or malfunction.
• Do not apply voltages that exceed the rated value to any Input Unit.
• Do not apply voltages or connect loads to the Output Units or slaves in excess of the maxi-
mum ratings.
• Turn ON the power after checking the connector wiring.
• Observe the following precautions when you wir
e communications cables. The communica-
tions cables may be broken or the Units may malfunction.
Do not fold communications cables.
Do not pull on communications cables with excessive
force. Secure communications
cables so that they are not pulled on excessively.
Do not place heavy objects on top of communications cables.
For a terminal block, cable ties can be used to secure the communications cable.
This section describes how to connect wires to the screwless clamping terminal block, the installation
and removing methods, and functions for preventing incorrect attachment.
You can connect ferrules that are attached to the twisted wires to the screwless clamping terminal
block. You can also connect the twisted wires or the solid wires to the screwless clamping terminal
block. If you connect the ferrules, all you need to do to connect the wires is to insert the ferrules into the
terminal holes.
\
Make sure that the voltages and currents that are input to the Units and slaves are within the speci-
fied ranges.
Inputting voltages or currents that are outside of the specified ranges may cause accidents or fire.
\
Be sure that all terminal screws and cable connector screws are tightened to the torque specified in
the relevant manuals. The loose screws may result in fire or malfunction.
