SAFETY PRECAUTIONS

Be sure to read this manual and all other attached documents carefully before installing,

operating inspecting or conducting maintenance on this unit. Always use this unit properly.

Be sure to carefully read the information about the device, the safety information and precautions

before using this unit. Be sure that the person(s) responsible for maintenance receives and

understands this manual completely.

This manual divides the safety precautions into DANGERs and CAUTIONs.

: Failure to observe these warnings may result in death or serious injury.

: Failure to observe these cautions may result in injury or property

damage.

Failuretoobserveany may lead to serious consequences.

All of these DANGERs and CAUTIONs provide very important precautions and should

always be observed.

Additional safety symbols representing a prohibition or a requirement are as follows:

: Prohibition. For example, “Do not disassemble” is represented by:

: Requirement. For example, if a ground is required, the following will be shown:

DANGER

CAUTION

REQUIREMENT

 An electric shock may lead to a deatch or burn. Noise may cause the system

to malfunction. Ground the line ground (LG), frame ground (FG), and shield

(SHD) terminals, as described below.

• Electrically insulate the mount base from the cubicle. To assure this, do not

remove the insulating sheet from the mount base.

• Ground the LG and FG terminals separately to prevent mutual interference.

The LG terminal is grounded to prevent intrusion of power line noise, while

FG and SHD terminals are grounded to suppress intrusion of line noise into

external interfaces for remote I/O modules, interface modules, and other

modules.

REQUIREMENT

 Excessive accumulation of heat in the cubicle may cause a fire or hardware

failure. When the temperature in the cubicle reaches 48°C or higher, the

maximum output current of the power supply module is limited. At 55°C, for

instance, it is limited to 5.85 A. Where this is very likely, install a cooling fan

in the cubicle or reduce the number of modules installed therein.

 The customer must not replace internal parts by themselves. Otherwise,

damage to internal parts may result. If the unit should fail, replace it on a

module basis.

DANGER

 Device an emergency stop circuit, interlock circuit, and other similar circuits

outside the programmable controller. Disregarding this rule may result in

damage to the equipment or cause an accident if the programmable controller

fails.

 Keep it in mind that this hardware unit operates on a high voltage. If the user

touches a high-voltage terminal inadvertently during connection or

disconnection of this hardware unit or its cable, he or she may suffer from an

electric shock. Also, this hardware unit may be damaged due to a short

circuit or noise. Be sure to switch off the hardware unit before connecting or

disconnecting it or its cable.

 Turn off the power before making connections to the terminal block. Wiring

with the power turned on may incur electrical shock hazards.

CAUTION

 High operating temperatures may cause the unit to fail. Further,

electromagnetic interference from adjacent equipment may cause the unit to

malfunction. Allow for clearances of specified dimensions between the

enclosure and the programmable controllers and between the programmable

controllers to assure heat dissipation and alleviate interference.

 During test running after mounting, measure the temperature around the

programmable controllers in the enclosure to make sure that they do no

exceed specified tolerances. If a clearance of specified dimensions is not

available between the programmable controllers or the measured temperature

is higher than specified, install a cooling fan to effect forced cooling.

 At an extremely high temperature, this hardware unit may fail. Secure the

mount base to a vertical surface. If the mount base is secured horizontally,

heat does not dissipate efficiently, resulting in an extremely high temperature.

This may further cause the hardware unit to fail or its parts to deteriorate.

 This hardware unit may be damaged due to static electricity. Ground yourself

before setting switches or connecting or disconnecting cables or connectors

with the hardware unit.

 This hardware unit may be damaged during its installation or removal unless

the following rules are observed:

• Check that the connector pins are not damaged (bent or broken), are aligned

straight and are free from dust.

• Move the hardware unit along an imaginary vertical surface to the face of the

mount base. If the product is inserted or removed slantwise from the

connector on the mount base, connector pins may be bent.

 Turn off the power before operating the MAIN/SUB selector switch or the CPU

No. selector switch. Operating these switches with the power turned on may

cause the module to fail.

PREFACE

We greatly appreciate your making use of an optional add-on to the S10mini Series CPU, called the

inter-CPU link module or, simply, CPU link module.

This hardware manual on the optional S10mini CPU link module explains how to handle the module.

Read this manual carefully to use the module properly.

For each S10mini Series product model, there are two types of product available: standard and

environmentally resistant.

The environmentally resistant product has thicker platings and coatings than those with the standard

one.

The model ID name of the environmentally resistant product is that of the standard product followed

by “-Z”.

Example: Standard product: LQE050

Environmentally resistant product: LQE050-Z

The manuals that come with the two types of S10mini Series product are identical. They describe

only standard products; however, users of an environmentally resistant product can also follow the

instructions given there without any problem. So, please follow the instructions for the proper use of

the product.
