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
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.
