waste.
5. Only use this product within a board whose structure allows no
possibility for fire to escape.
About Installation
1. When wiring, use only recommended crimp terminals.
2. Do not block areas around the product for proper dissipation of
heat. (If you do not secure space for heat dissipation, life cycle of
the product will be compromised.)
3. To avoid electrical shocks, make sure that power is not supplied to
the product while wiring.
4. To avoid electrical shocks, make sure that power is not supplied to
the product when performing DIP switch settings.
Noise Countermeasures
1. Do not install the product near devices generating strong high
frequency waves or surges.
2. When using a noise filter, check the voltage and current and
install it as close to the product as possible.
3. In order to prevent inductive noise, wire the lines connected to the
product separately from power lines carrying high voltages or
currents. Do not wire in parallel with or on the same cable as
power lines.
Other measures for reducing noise include running lines along
separate ducts and using shield lines.
To avoid faulty operations,
malfunctions, or failure, observe the
following operating instructions.
1. When turning on the power, make sure to realize rated voltage
within 1 second from the time of first supply of electricity.
2. Make sure to use power supply for operations, inputs, and
transformer with the appropriate capacity and rated burden.
3. Maintenance and handling of this product may only be performed
by qualified personnel.
4. Distortion ratio of input wave forms must be 30% or less. Use of
this product with circuits that have large distortion in wave forms
may result in unwanted operations.
5. Using this product for thyristor controls or inverters will result in
errors.
6. When setting the volume, adjust the control from the minimum
side to the maximum side.
Checking Operation
Overvoltage
Gradually increase the input from 80% of the setting.
The input value will equal the operating value when the
input exceeds the setting and the alarm indicator starts
