1-3. Inspecting the Unit.
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 panel surfaces are free of dents and scratches.
▌Check the broken rear output terminals.
▌Check the cabinet is free of scratches.
▌Check the LDC display is not scratched or cracked.
Electrical Check
▌When turning on the power, check the alarm sound.
If the alarm sounds, the instrument has the error during self-testing itself.
Error checking, press the error key and conform error code.
More information about error code, refer to “7.Error Messages”.
About Self-test, refer to 『1-6. Check after Power On』.
▌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.

EX Series Operating Manual
1-5. Check Before Power On
Output Terminal Check
▌Check the rear panel outputs for voltage sensing and rear main outputs.
<Figure 1-1>
Floating the power supply output more than ±60 Vdc from the chassis presents an
electric shock hazard to the operator. Do not float the outputs more than ±60 Vdc
when metal shorting material or wire without insulation are used to connect
the (+) output to the (+) sense and the (-) output to the (-) sense terminals.
Outputs can be floated to maximum of ±240 Vdc provided that the metal shorting wire
without insulation are either replaced with insulated conductors or they are removed
from the terminals so there is no operator access to the output conductors without
insulation. All field wiring insulation must be adequate for the voltage present.
<Figure 1-2>

WARNING
WARNING

EX Series Operating Manual
▌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 receptacle. Do not operate your power
supply without adequate cabinet ground connection.
Input AC 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. AC100V, 110V, 115V, 230V input power is optional.
Refer to chapter "1-2. Accessories & Options"
▌In other to prevent the instrument severe damage from overload, fuse is built-in
(1U, 2U products) or braker(3U products) is installed rear side. If fuse also is
broken or braker is turned down repeatedly when power turns on, check the
input power line or broken braker and then call to nearest ODA Technologies
A/S Center
If products maximum output capacity is over 5KW, fuse will be replaced to Breaker.

1-6. Check After Power On.
The power-on test includes an automatic self-test that checks the internal microprocessors
and allows the user visually to check the display. You will observe the following sequence
on the display after pressing the front panel power switch to on. And also keep the
ex-remote and voltage value is zero and current value is max value.OVP & OCP level are
set to maximum output value of instrument capacity and it is under the vigilance.
Display Procedure on the LCD
▌Display "ODA Technologies".
▌Display "EX-Series Ver1.3"
▌Annunciators of ERR,LMT,RMT,LOCK on front side are lit and go off clockwise from
the left.
CV & CC annunciators are not applied.
▌During displaying above procedure, the instrument is initialized by stored in non-
volatile memory.
▌Also the instrument runs automatic self-test below mentioned.
Connection test between front panel and connector.
Remote interface test Check remote interface for PC communication.
Memory data confirm test Check product information and related setting.
ADC H/W error test Check error on ADC control condition.
Unregulated state test Check output voltage floating state.
ADC/DAC calibration test check ADC & DAC Calibration data state.
If the error occurs, alarm beeps and the error code is saved to volatile memory
automatically. You can read the error code by pressing error key.
About error code explanation, refer to “7. Error Messages”.

1-7. Installation.
Cooling
▌The power supply can operate without loss of performance within the temperature range
of 0 °C to 40 °C, and with derated output current from 40 °C to 55 °C. 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. 1-4 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.
Rack Mounting
▌Our products dimension is based on 1U * 19inch full rack size and we provide front rack
bracket basically when you purchase our goods.
