CAUTION
1. Items related to noise
Always treat the shield cables indicated in this manual with grounding measures such as cable
clamps.
Separate the signal wire from the drive line/power line when wiring.
2. Items related to installation
Install the unit on noncombustible material. Installation directly on or near combustible material may
lead to fires.
Always observe the installation direction.
Do not install or operate a unit that is damaged or that have missing parts.
Do not allow conductive foreign matter such as screws or metal chips or combustible foreign matter
such as oil enter the unit.
The unit is a precision device so does not drop or apply strong impacts on them.
Do not install the unit where it may be subject to cutting oil.
3. Items related to connection
Do not apply voltages other than those indicated in this manual on the connector. Doing so may
lead to destruction or damage.
Incorrect connections may damage the devices, so connect the cables to the specified connectors.
When using an inductive load such as relays, always connect a diode in parallel to the load as a
noise measure.
When using a capacitive load such as a lamp, always connect a protective resistor serially to the
load to suppress rush currents.
Do not connect or disconnect the connection cables between each unit while the power is ON.
When using an RS-232C device as a peripheral device, caution will be required when connecting
and disconnecting the connector.
Always use a double-OFF type AC power supply switch on the device side, and connect/
disconnect the connector with the AC power supply on the device side OFF.
