1. Handling Precautions
- Do not touch components inside of the converter; otherwise, it will
cause electric shock.
- Do not damage the cable by applying excessive load, placing heavy
objects on it, or clamping; otherwise, it will cause electric shock or fire.
- Turn the power supply OFF before wiring, transporting, and
inspecting the converter; otherwise, it may cause electric shock.
- Provide an external safety circuit so that the entire system functions
safely even when the converter is faulty.
- Connect the grounding terminal of the converter; otherwise, it may
cause electric shock or malfunction.
- Do not use the converter in the following places; water splashes, the
atmosphere of the corrosion, the atmosphere of the flammable vapor,
and the side of the combustibility. Doing so may result in fire or the
converter may become faulty.
- Be sure to use the converter and the ABSOCODER sensor in the
environment designated by the general specifications in the manual.
Failure to do so may result in electric shock, fire, malfunction or unit
failure.
- Be sure to use the specified combination of the ABSOCODER
sensor, the converter and sensor cable; otherwise, it may cause fire or
the converter malfunction.
2. Storage
- Do not store the converter in a place exposed to water, or toxic gas
and liquid.
- Be sure to store the converter in designed temperature and humidity
range, and do not expose to direct sunlight.
- Be sure to consult with NSD when the converter is stored for long
periods.

3. Transport
- Do not hold the cable or shaft of ABSOCODER sensor during transport;
otherwise, it will cause injury or malfunction.
4. Installation
- Do not step on ABSOCODER sensor or place heavy objects on the
converter; otherwise, it will cause injury or malfunction.
- Do not block the exhaust port or allow any foreign matter to enter the
converter; otherwise, it will cause fire or the converter failure.
- Be sure to secure the converter and ABSOCODER sensor with the
provided brackets; otherwise, it may cause malfunction, injury, or drop.
- Be sure to secure the specified distance between the converter and
the control panel or other equipment; otherwise, it may cause
malfunction.
5. Wiring
- Be sure to secure the terminal block firmly; otherwise, it will cause fire.
- Be sure to mount the terminal cover provided with the converter,
before supplying the power, starting operation after the installation, and
wiring; otherwise, it may cause electric shock.
- Be sure to keep the sensor cable, control cable, and communication
cable at least 300 mm away from the main circuit and power line;
otherwise it may cause injury or malfunction.
- Be sure to connect all cables correctly; otherwise, it may cause injury
or malfunction.
- Be sure to firmly connect the external I/O connectors and sensor
connectors; otherwise, it may cause incorrect inputs and outputs or
injury.
6. Operation
- Do not change the converter 's function switch settings during the
operation; otherwise, it will cause injury.
- Do not approach the machine after instantaneous power failure has
been recovered. Doing so may result in injury if the machine starts
abruptly.
- Be sure to check that the power supply specifications are correct;
otherwise, it may cause the converter failure.
- Be sure to provide an external emergency stop circuit so that
operation can be stopped with power supply terminated immediately.
- Be sure to conduct independent trial runs for the converter before
mounting ABSOCODER sensor to the machine; otherwise, it may
cause injury.
- When an error occurs, be sure to eliminate the cause, ensure safety,
and reset the error before restarting operation; otherwise, it may cause
injury.
7. Maintenance and Inspection
- Do not disassemble, remodel, or repair the unit; otherwise, it will
cause electric shock, fire, and unit malfunction.
- The capacitor of the power line deteriorates through prolonged use.
We recommended that the capacitor be replaced every five years to
prevent secondary damage.
8. Disposal
- Be sure to handle the converter and ABSOCODER sensor as
industrial waste while disposing of it.
