[Installation Precautions]

CAUTION

z Use the programmable controller in the operating environment that meets

the general specifications given in the user’s manual of the CPU module.
Using this programmable controller in an environment outside the range of
the general specifications could result in electric shock, fire, erroneous
operation, and damage to or deterioration of the product.

z While pressing the installation lever located at the bottom of module, insert

the module fixing tab into the fixing hole in the base unit until it stops.
Then, securely mount the module with the fixing hole as a supporting point.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the programmable controller in the environment of much
vibration, tighten the module with a screw.
Tighten the screw in the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage
to the screw or module.

z Completely turn off the externally supplied power used in the system before

mounting or removing the module.
Not doing so could result in damage to the product.

z Do not directly touch the module's conductive parts or electronic

components.
Touching the conductive parts could cause an operation failure or give
damage to the module.

z Completely turn off the externally supplied power used in the system when

installing or placing wiring. Failure to do so may cause malfunction or failure
of the module.

[Wiring Precautions]

DANGER

z Completely turn off the externally supplied power used in the system when

installing or placing wiring.
Failure to do so may cause electric shocks or damage the product.

CAUTION

z Always connect the FG terminals to the ground using class D (class 3) or

higher grounding exclusively designed for programmable controller.
Failure to do so may cause malfunctions.

z When connecting cables to the terminal block for external power supply,

check the rated voltage and terminal layout of the product for correct wiring.
Connecting a power supply that is different from the rating or incorrectly
wiring the product could result in fire or damage.

z Tighten the terminal screws with the specified torque.

If the terminal screws are loose, it could result in short circuits, fire, or
erroneous operation.

z Solder coaxial cable connectors properly. Incomplete soldering may result in

malfunctioning.

z Be sure there are no foreign substances such as sawdust or wiring debris

inside the module.
Such debris could cause fires, damage, or erroneous operation.

z The module has an ingress prevention label on its top to prevent foreign

matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.

z Make sure to place the communication and power cables into a duct or

fasten them using a clamp. Failure to do so may damage the module or
cables by pulling a dangling cable inadvertently or cause the module to
malfunction due to bad connection.

z When disconnecting the communication and power cables from the module,

do not pull a cable part by hand.
When disconnecting a cable with a connector, hold the connector connected
to the module by hand and pull it out to remove the cable. When
disconnecting a cable connected to a terminal block, loosen the screws on
the terminal block first before removing the cable. If a cable is pulled while
being connected to the module, it may cause the module to malfunction or
damage the module and cables.
