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

DANGER

 Devise 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.

CAUTION

 This hardware unit may fail if the ambient temperature is too high. The

hardware unit may also malfunction due to interference by electromagnetic

waves from adjacent hardware. To dissipate heat and reduce

electromagnetic interference, provide the specified mount of space between

the cubicle and this hardware unit and between the hardware unit and other

ones.

 After installing this hardware unit, measure temperatures near the in-cubicle

controller and the mount base during operation, and check whether the

measurements are within the limits. If the specified amount of space cannot

be provided or the measured temperature is too high, use a cooling fan.

 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 damage (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.

REQUIREMENT

Electric shock hazards exist so that you might suffer burns or become

electrocuted. Further, the system might malfunction due to noise interference.

Therefore, ground the line ground (LG), frame ground (FG), and shield wire

(SHD) as directed below:

• Insulate the mount base from the enclosure. To keep the mount base

insulated, avoid removing the insulation sheets that are supplied with the mount

base.

• The LG is a ground terminal for power supply noise. The FG and SHD are

ground terminals for the noise in the communication module and other external

interface lines. To avoid interference between the ground terminals,

separately ground the LG and FG.

• Ground the module’s FG by shorting it to the mount base’s FG terminal. Note,

however, that the FG terminal for each remote I/O line or JPCN-1 line must be

connected separately to a single place on the terminating side.

REQUIREMENT

 A surge voltage may cause hardware units to malfunction or to be damaged.

Where a coil such as one in an electromechanical relay is connected to the

PCs’ OK output circuit, protect the relay with a surge-absorbing diode that is

capable of withstanding a peak inverse voltage of at least 10 times the circuit

voltage and has a forward current equal to or larger than the load current.

 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.

 If the battery is handled improperly, it may catch fire or explode. Some used

batteries may still have a considerable amount of charge. To deliver such

used batteries to a waste disposal site safely, follow the general rules for

collection, packing, and transportation. For concrete methods of packing and

transportation, consult with professionals of your local waste disposal

business.

PROHIBITION

If a part in a module is damaged, do not replace the part, but replace the faulty

module in its entirety, except when the part is the battery for the CPU.
