Safety Precautions
This section describes precautions that apply to ladder programming. Before programming,
always read this manual and all other documents provided to ensure correct programming.
Before using the equipment, familiarize yourself with equipment details, safety information,
and all other precautions.
Handling
Installation
• Do not subject the product to halogen gases, such as fluorine, chlovine, bromine, and
iodine, at any time even during transportation or installation.
Failure to observe this caution may cause damage or failure of the product.
• Firmly tighten the Module mounting screws and terminal block mounting screws to pre-
vent them from loosening during operation.
Loose screws may result in a malfunction of the MP920.
• Always turn OFF the power supply to the Module before installing it.
• Insert the connectors of the cables that are to be connected to the MP920 Modules and
secure them well.
Incorrect insertion of the connectors may result in a malfunction of the MP920.
CAUTION
CAUTION

viii
Wiring
• Always connect a power supply that meets the given specifications.
Connecting an inappropriate power supply may cause fires.
• Wiring must be performed by qualified personnel.
Incorrect wiring may cause fires, product failure, or electrical shocks.
• Do not accidentally leave foreign matter such as wire chips on the Mounting Base or in
the Module when wiring.
This may cause fires, failures, and malfunctions.
CAUTION
• Always ground the FG terminal to a ground resistance 100Ωor less.
Failure to ground the MP920 may result in electrical shocks or malfunctioning.
Select, separate, and lay external cables correctly.
• Consider the following items when selecting the I/O signal lines (external cables) to
connect the MP920 Module to external devices.
• Mechanical strength
• Noise interference
• Wiring distance
• Signal voltage, etc.
• Separate the I/O signal lines from the power lines both inside and outside the control
panel to reduce the influence of noise from the power lines.
If the I/O signal lines and power lines are not separated properly, malfunctioning may result.

ix
Application
Maintenance
• Do not touch any Module terminals when the system power is ON.
There is a risk of electrical shock.
WARNING
• Do not attempt to modify the MP920 programs, force outputs, switch between RUN and
STOP, or perform other similar operations while the MP920 is operating without know-
ing the direct and indirect consequences of the operation.
Incorrect programming or operation may damage the equipment or cause an accident.
CAUTION
• Make sure that the polarity of the Module’s built-in battery is correct. The battery must
be installed correctly and must not be charged, disassembled, heated, thrown into fire,
or short-circuited.
Improper handling may cause the battery to explode or ignite.
WARNING
• Do not attempt to disassemble or modify the MP920 Modules in any way.
Doing so can cause fires, product failure, or malfunctions.
• The customer must not replace any built-in fuses.
If the customer replaces a built-in fuse, the MP920 Module may malfunction or break down.
The built-in fuse must always be replaced by Yaskawa service staff.
PROHIBITED
