Using the High Voltage BCM TM Evaluation Board
Important Information
WARNING: Hazardous voltages are present on the High Voltage 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 High Voltage 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.
1) The High Voltage BCM ® Evaluation Board does not contain a fuse. ALWAYS use a fuse
upstream of the evaluation board when operating under power.
2) ALWAYS remove power before touching, servicing, or attaching probes to the High Voltage
BCM Evaluation Board. Verify that the power is removed before touching. Physically disconnect
input power or use a lockout / tagout (LOTO) system to prevent the accidental application of
power while servicing the evaluation board.
3) While the High Voltage BCM Evaluation Board is designed to demonstrate the use of BCM bus
converters in offline systems, for general laboratory evaluation, it is highly recommended for
safety purposes to use an isolated high voltage source for the evaluation board. This source
can be a bench top regulated high voltage DC source, or an offline PFC front end powered
through an ISO-VAC or line isolation transformer.
4) NEVER leave the High Voltage BCM Evaluation Board unattended when under power.
5) Provide strain relief for wires and place the High Voltage BCM Evaluation Board on the bench
in such a way as to prevent accidental dislodgement from the bench top. Connecting wires or
attached probes should not hang off the bench.
6) Use appropriate shielding of exposed high voltage areas of the High Voltage BCM Evaluation
Board to prevent accidental casual contact.
7) The High Voltage BCM Evaluation Board is designed for use in a laboratory environment.
Use of the evaluation board in other environments is not recommended.
