hazardous conditions, resulting in death or severe
injury.
Indicates that incorrect handling may cause
hazardous conditions, resulting in minor or moderate
injury or property damage.
A-1
[Design Precautions]
DANGER
Configure a safety circuit so that the safety of the overall system is
maintained even if an external power failure or a programmable controller
failure occurs.
Incorrect output or malfunction can lead to an accident.
(1) The status of analog output changes depending on the setting of various
functions that control the analog output. Take sufficient caution when
setting for those functions.
For details of analog output status, refer to Section 3.4.1 "Combinations
of functions in each part" in the User's Manual.
(2) Normal output may not be obtained due to malfunctions of output
elements or the internal circuits.
For output signals that may cause a serious accident, provide an
external monitoring circuit.
CAUTION
Do not install the control or communication cable(s) together with the main
circuit or power cables.
Keep a distance of 100mm or more between them.
Failure to do so may cause malfunctions due to noise.
At power ON/OFF, voltage or current may instantaneously be output from the
output terminal of this module.
In such case, wait until the analog output becomes stable to start controlling
the external device.
A-2
[Installation Precautions]
CAUTION
Use the module in an environment that meets the general specifications
given in this manual.
Operating it in any other environment may cause an electric shock, fire,
malfunction, product damage or deterioration.
For protection of the switches, do not remove the cushioning material before
installation.
Securely fix the module with the DIN rail or fixing screws. Fixing screws must
be tighten within the specified torque range.
A loose screw may cause a drop of the module or malfunction.
Overtightening may damage the screw, resulting in a drop or malfunction of
the module.
Do not directly touch any conductive part of the module.
Doing so may result in a malfunction or failure of the module.
A-3
[Wiring Precautions]
CAUTION
Be sure to shut off all phases of the external power supply used by the
system before installation or wiring.
Failure to do so may cause a damage to the product and/or malfunctions.
Always ground the FG terminal to the protective ground conductor.
Failure to do so may result in malfunctions.
Be sure to tighten any unused terminal screws within a tightening torque
range.
Failure to do so may cause a short circuit due to contact with a solderless
terminal.
Use applicable solderless terminals and tighten them with the specified
torque.
If any solderless spade terminal is used, it may be disconnected when the
terminal screw comes loose, resulting in failure.
Check the rated voltage and terminal layout and then wire the module
correctly.
Connecting a power supply of a different voltage rating or incorrect wiring
may cause a fire or failure.
Tighten terminal screws within the specified torque range.
A loose terminal screw may cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to damage of the
screws or module.
Take care to prevent foreign matter such as dust or wire chips from entering
the module.
Failure to do so may cause a fire, failure or malfunctions.
Place the connection wires and cables in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module and/or cables or malfunctions due to poor cable
connection.
A-4
[Wiring Precautions]
CAUTION
Do not install the control cable(s) together with the communication cable(s).
Doing so may cause malfunctions due to noise.
When disconnecting the cables from the module, do not hold and pull the
cable part.
Disconnect the cables after loosening the screws in the portions connected
to the module.
Pulling the cable that is still connected to the module may damage the
module and/or cable and cause malfunctions due to poor cable connection.
[Starting and Maintenance Precautions]
CAUTION
Do not touch the terminals while the power is on.
Doing so may cause malfunction.
Be sure to shut off all phases of the external power supply used by the
system before cleaning or retightening the terminal screws.
Not doing so can cause the module to fail or malfunction.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage
of the screws or module.
Never disassemble or modify the module.
This may cause breakdowns, malfunction, injury and/or fire.
Do not drop or apply any strong impact to the module. Doing so may damage
the module.
Be sure to shut off all phases of the external power supply used by the
system before mounting or dismounting the module to or from the panel.
Not doing so can cause the module to fail or malfunction.
Do not install/remove the terminal block more than 50 times after the first use
of the product. (IEC 61131-2 compliant)
Before handling the module, always touch grounded metal, etc. to discharge
static electricity from the human body.
Failure to do so can cause the module to fail or malfunction.
[Disposal Precautions]
CAUTION
When disposing of this product, treat it as industrial waste.
