CAUTION
Depending on circumstances, procedures indicated by CAUTION may also be linked to serious results. In any case, it is important to follow the directions for usage. Store this manual in a safe place so that you can take it out and read it whenever necessary. Always forward it to the end user.
Procedures which may lead to a dangerous condi tion and cause superficial to medium injury, or physical damage only, if not carried out properly.
[DESIGN PRECATUIONS]
DANGER
Input/output could be switched on or off when a problem occurs in the
repeater module. So build an external monitoring circuit that will monitor any input/output signals that could cause a serious accident.
CAUTION
Use each module in an environment as specified in the "general
specification" in the CPU module User's Manual. Usage of the module outside the general specification range may cause electric shock, fire, malfunction, product damage or deterioration.
Do not have control cables and communication cables bundled with or
placed near by the main circuit and/or power cables. It may cause malfunction due to noise interference. Wire those cables at least 100mm(3.94 inch) away from the main circuit and/or power cables.
[INSTALLATION PRECAUTIONS]
CAUTION
Do not directly touch the module's conductive parts.
Doing so could cause malfunction or trouble in the module.
Tighten the module securely using DIN rail or installation screws within the
specified torque range. Loose terminal screws may cause falling, short circuit or erroneous operation. If the terminal screws are too tight, it may cause falling or short circuit due to damage of the screws.
[WIRING PRECAUTIONS]
DANGER
Perform installation and wiring after disconnecting the power supply at all
phases externally. If the power is not disconnected at all phases an electric shock or product damage may result.
CAUTION
Be sure to ground the FG terminal to the class-D (class 3) or higher
sequencer dedicated grounding conductor. Otherwise there will be an electric shock or misoperation.
Terminal screws which are not to be used must be tightened always.
Otherwise there will be a danger of short circuit against the bare solderless terminals.
Perform correct wiring for the module according to the product's rated
voltage and terminal arrangement. Connecting to a power supply different from the rating or mis-wiring may cause fire and/or trouble.

[WIRING PRECAUTIONS]
CAUTION
Fix terminal screws securely with the specified torque.
Loose terminal screws may cause short circuit or malfunction. If the terminal screws are too tight, it may cause falling, short circuit or erroneous operation due to damage of the screws or module.
Make sure foreign objects do not get inside the module, such as dirt and
wire chips. It may cause fire, trouble or malfunction.
Be sure to fix the communication and power cables that are connected to
the module in place, either by running them through a duct or by using clamps. If the cables are not fixed in one of these ways, dispersion, movement, or careless pulling of the cables may cause damage to the module or cables, or malfunction due to cable contact faults.
When removing the communication cable or power supply cable from the
module, do not pull the cable. When removing the cable with a connector, hold the connector on the side that is connected to the module. When removing the cable connected to the terminal block, first loosen the screws on the part that is connected to the terminal block. Pulling the cable that is still connected to the module may cause malfunction or damage to the module or cable.
[STARTUP AND MAINTENANCE PRECAUTIONS]
DANGER
Do not touch terminals when the power is on.
It may cause an electric shock or malfunction.
Perform cleaning the module or re-tightening of terminal screws after
making sure to turn off the external power supply. If you do not switch off the external power supply, it will cause trouble or malfunction of the module.
CAUTION
Never try to disassemble or modify module.
It may cause trouble, malfunction, injury or fire.
The module case is made of resin; do not drop it or subject it to strong
shock. Module damage may result.
Make sure to switch all phases of the external power supply off before
installing or removing the module to/from the panel. If you do not switch off the external power supply, it will cause trouble or malfunction of the module.

phases externally. If the power is not disconnected at all phases an electric shock or product damage may result.
Do not touch terminals when the power is on. It may cause an electric
shock or malfunction.
Perform cleaning the module or re-tightening of terminal screws after
making sure to turn off the external power supply. If you do not switch off the external power supply, it will cause trouble or malfunction of the module.
13
CAUTION
Use each module in an environment as specified in the "general
specification" in the CPU module User's Manual. Usage of the module outside the general specification range may cause electric shock, fire, malfunction, product damage or deterioration.
Do not have control cables and communication cables bundled with or
placed near by the main circuit and/or power cables. It may cause malfunction due to noise interference. Wire those cables at least 100mm(3.94 inch) away from the main circuit and/or power cables.
Do not directly touch the module's conductive parts.
Doing so could cause malfunction or trouble in the module.
Tighten the module securely using DIN rail or installation screws within the
specified torque range. Loose terminal screws may cause falling, short circuit or erroneous operation. If the terminal screws are too tight, it may cause falling or short circuit due to damage of the screws.
Fix terminal screws securely with the specified torque.
Loose terminal screws may cause short circuit or erroneous operation. If the terminal screws are too tight, it may cause falling, short circuit or erroneous operation due to damage of the screws or module.
Be sure to ground the FG terminal to the class-D (class 3) or higher
sequencer dedicated grounding conductor. Otherwise there will be an electric shock or misoperation.
Terminal screws which are not to be used must be tightened always.
Otherwise there will be a danger of short circuit against the bare solderless terminals.
Perform correct wiring for the module according to the product's rated
voltage and terminal arrangement. Connecting to a power supply different from the rating or mis-wiring may cause fire and/or trouble.
Make sure foreign objects do not get inside the module, such as dirt and
wire chips. It may cause fire, trouble or malfunction.
Be sure to fix the communication and power cables that are connected to
the module in place, either by running them through a duct or by using clamps. If the cables are not fixed in one of these ways, dispersion, movement, or careless pulling of the cables may cause damage to the module or cables, or malfunction due to cable contact faults.
When removing the communication cable or power supply cable from the
module, do not pull the cable. When removing the cable with a connector, hold the connector on the side that is connected to the module. When removing the cable connected to the terminal block, first loosen the screws on the part that is connected to the terminal block. Pulling the cable that is still connected to the module may cause malfunction or damage to the module or cable.
14
CAUTION
Never try to disassemble or modify the module.
It may cause trouble, malfunction, injury or fire.
The module case is made of resin; do not drop it or subject it to strong
shock. A module damage may result.
Make sure to switch all phases of the external power supply off before
installing or removing the module to/from the panel. If you do not switch off the external power supply, it will cause trouble or malfunction of the module.
