[Installation Precautions]

CAUTION

zUse the programmable controller in the operating environment that meets

the general specifications given in the CPU module used.

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.

zWhile 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.

zCompletely 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.

zFor remote I/O stations of function version D or later, online module change

can be performed. However, the modules which can be replaced online are

limited, and replacement procedures are determined for each module.

For details, refer to the Q Corresponding MELSECNET/H Network System

Reference Manual (Remote I/O network).

zDo 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.

zBefore touching the module, always touch grounded metal, etc. to discharge

static electricity from human body, etc. Not doing so can cause the module

to fail or malfunction.

[Wiring Precautions]

DANGER

zCompletely turn off the externally supplied power used in the system when

placing wiring.

Not completely turning off all power could result in electric shock or damage

to the product.

CAUTION

zSolder coaxial cable connectors properly. Incomplete soldering may result in

malfunction.

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

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

operation.

zThe 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.

zMake sure to place the communication and power cables to be connected to

the module in a duct or fasten them using a clamp. If the cables are not

placed in a duct or not fastened with a clamp, their positions may become

unstable and may move, or they may be pulled inadvertently. This may

damage the module and the cables or cause the module to malfunction

because of faulty cable connections.

zWhen disconnecting a communication cable, do not pull it by holding the

cable part.

To disconnect the cable, hold its connector that is plugged into the module.

Pulling the cable part with the cable still connected to the module may

damage the module and/or cable, or cause malfunctions due to poor cable

contact.

zInstall our programmable controller in a control panel for use. Wire the main

power supply to the power supply module installed in a control panel through

a distribution terminal block. Furthermore, the wiring and replacement of a

power supply module have to be performed by a maintenance worker who

acquainted with shock protection. (For the wiring methods, refer to QCPU

User's Manual (Hardware Design, Maintenance and Inspection).)
