＜High Voltage Safety Precautions＞

◇Read all safety precautions before use

Please note that this document covers only the BM2SC123FP2-LBZ evaluation board

(BM2SC123FP2-EVK-001) and its functions. For additional information, please refer to

the datasheet.

To ensure safe operation, please carefully read all precautions before

handling the evaluation board

Depending on the configuration of the board and voltages used,

Potentially lethal voltages may be generated.

Therefore, please make sure to read and observe all safety precautions described in

the red box below.

Before Use

[1] Verify that the parts/components are not damaged or missing (i.e. due to the drops).

[2] Check that there are no conductive foreign objects on the board.

[3] Be careful when performing soldering on the module and/or evaluation board to ensure that solder

splash does not occur.

[4] Check that there is no condensation or water droplets on the circuit board.

During Use

[5] Be careful to not allow conductive objects to come into contact with the board.

[6] Brief accidental contact or even bringing your hand close to the board may result in

discharge and lead to severe injury or death.

Therefore, DO NOT touch the board with your bare hands or bring them too close to the board.

In addition, as mentioned above please exercise extreme caution when using conductive tools such as

tweezers and screwdrivers.

[7] If used under conditions beyond its rated voltage, it may cause defects such as short-circuit or,

depending on the circumstances, explosion or other permanent damages.

[8] Be sure to wear insulated gloves when handling is required during operation.

After Use

[9] The ROHM Evaluation Board contains the circuits which store the high voltage. Since it stores the

charges even after the connected power circuits are cut, please discharge the electricity after using

it, and please deal with it after confirming such electric discharge.

[10] Protect against electric shocks by wearing insulated gloves when handling.

This evaluation board is intended for use only in research and development facilities and

should by handled only by qualified personnel familiar with all safety and operating

procedures.

We recommend carrying out operation in a safe environment that includes the use of high

voltage signage at all entrances, safety interlocks, and protective glasses.

Operation Procedure

1. Operation Equipment

(1) 3 Phase AC Power supply 210 Vac to 480 Vac, or DC Power supply 300 Vdc to 900 Vdc. (80 W or more)

(2) Electronic Load capacity 2.0 A

(3) DC voltage meter

2. Connect method

(1) Turn off each power supply and connect the measuring instrument as shown below.

(2) Set the power supply within the usage range and turn on the power.

(3) If using electronic load, set it between 0 A to 2 A.

(4) Connect the output DC voltage meter directly to the output and measure the voltage by sensing.

(5) When removing the measuring instrument, set the input voltage to 0 V and check that the voltage of the input electrolytic

capacitors C8, 9, 10 are 10 V or less. After that, turn off the power of each measuring instrument and remove it.

(Note that you may get an electric shock if high voltage remains in the input capacitor.)
