1-3. Check
When you receive your power supply, inspect it for any obvious damage that may have
occurred during shipment. If any damage is found, notify the carrier and the nearest ODA
Sales Office immediately. Warranty information is shown in the front of this manual. Keep
the original packing materials in case the power supply has to be returned to ODA
Technologies in the future. If you return the power supply for service, attach a tag
identifying the owner and model number. Also include a brief description of the problem.
Mechanical Check
▌Check the broken key, encoder switch, power switch.
▌Check the broken output terminals.
▌Check the panel surfaces are free of dents and scratches.
▌Check the cabinet is free of scratches.
▌Check the LCD display is not scratched or cracked.
Electrical Check
▌When turning on the power, it shows instrument model and ODA website at first.
▌Check the model Number is matched with displayed model number.
▌After it shows "**OUTPUT OFF**" message, verifies to a high level of confidence
that the power supply is operating in accordance with its specifications.

Floating the power supply output more than ±60 Vdc from the chassis presents an
electric shock hazard to the operator.
Power Cord Check
▌Your power supply is equipped with a 3-wire grounding type power cord; the third
conductor being the ground. The power supply is grounded only when the power-
line cord is plugged into an appropriate receptable. Do not operate your power
supply without adequate cabinet ground connection.
WARNING

Input Power Line Check
▌You can operate your power supply from a nominal 198-242 V single phase AC
power source at 47 to 63 Hz. AC 100V, 110V, 115V, 230V input power is optional.
Refer to chapter "1-2, Accessories & Options"
▌In order to prevent the instrument severe damage from overload, fuse is installed
in inlet case. If the fuse is also repeatedly when power turns on, check the
input power line or broken breaker and then call to nearest ODA Technologies A / S Center
Input power connection is following.

1-6. Check After Power On
When turning on the power switch, the front-panel display will light up briefly while the
instrument performs its power-on default value setting. And also keep the ex-remote
interface setting mode, voltage value is zero and current value is max value.
Display Procedure on the LCD
▌Display "OPE-303S V1.0" and website address
Visit ODA Technologies website. Get the manuals, windows application software demo, and upgrade
information & technical support.
▌Display "**OUTPUT OFF**"
▌By using front panel key and encoder switch, set the voltage/current and functions.
Default Setting Values
▌Output Voltage : 0V ▌Cursor location : Default voltage.
▌Output Current : Limit setting max value Voltage : 1V Unit
▌Output Select : Voltage Current : 0.1A Unit
▌Remote Interface : ex-remote interface setting mode
▌After standby mode : Display "**OUTPUT OFF**"
The RS232C is attached in the instrument when the power supply is shipped from the
factory for remote interface configuration and baud rate is set 9600bps at first time.
In case of choosing RS 485 interface, address no. is 05 when this is shipped from the factory.
For your safety, Setting Voltage and Current will not be set up after turn-on.
After power on, power supply will be in "**OUTPUT OFF**" Mode.

1-7. Installation
Cooling
▌The power supply can operate without loss of performance within the
temperature range of 0℃ to 40℃, and with derated output current from
40℃ to 55℃. A fan cools the power supply by drawing air through the rear
panel and exhausting it out the sides. Using an ODA rack mount will not
impede the flow of air.
< figure 1-6 Bottom view>
Bench Operation
▌Your power supply must be installed in a location that allows sufficient space
at the sides and rear of the power supply for adequate air circulation.
