IMPORTANT NOTICE:
Hazardous voltages are present on the HV BCM Evaluation Board under power.
PERSONAL CONTACT WITH LINE VOLTAGE MAY RESULT IN SEVERE INJURY, DISABILITY,
OR DEATH. IMPROPER OR UNSAFE HANDLING OF THIS BOARD MAY RESULT IN
SERIOUS INJURY OR DEATH.
Read the precautions below entirely BEFORE using the HV BCM Evaluation Board. Do
not operate the evaluation board unless you have the appropriate safety precautions
in place on your bench to guarantee safety.
The list below is not comprehensive and is not a substitute for common sense
and good practice.
n During operation, the power devices and surrounding structures can be operated
safely at high temperatures.
n Remove power and use caution when connecting and disconnecting test probes
and interface lines to avoid inadvertent short circuits and contact with hot surfaces.
n When testing electronic products always use approved safety glasses. Follow good
laboratory practice and procedures.
n Avoid creating ground loops when making measurements of the isolated input or
output voltage.
n Care should be taken to protect the user from accidental contact when
under power.
n Care should be taken to avoid reversing polarities if connecting to the opposite
(solder) side of the board.
n The Customer Evaluation Board described in this document is intended to
acquaint the reader with the benefits and features of high voltage distribution.
They are not designed to be installed in end-use equipment.
n Refer to the specific HV BCM module data sheet for electrical details.
