[DESIGN PRECATUIONS]
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.
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]
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]
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.
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.
