High Voltage Safety Precautions

 


ۍ

 Read all safety precautions before use 

 
  Please note that this document covers only the BM1Z002FJ evaluation board 

(BM1Z002FJ-EVK-002) 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.
