3.1. Safety Precautions ***** WARNING *****

Before applying power to the FEBSPM3SPM45_M01MTCA evaluation board, it is

imperative that all involved personnel read and understand the safety precautions and

understand the power on/off procedures.

The FEBSPM3SPM45_M01MTCA evaluation board operates at lethal voltages and has

bulk capacitors that store significant charge. Accidental contact can lead to lab equipment

damage, personnel injury, and may be fatal. Please be exceptionally careful when probing

and handling this board. Always observe normal laboratory precautions, including:

AC mains before operating voltages are applied to the board. Alternatively, AC/DC

power to the board may be isolated.

Alternatively, high-voltage (700 V+) isolated probes may be utilized.

presence of HIGH VOLTAGES. When bulk capacitors are charged, avoid contact

with board circuitry.

MCU. One way to do this is to remove the main power source while the motor is still

motoring with the MCU active. The motor then discharges the output capacitors and

the module is safe to disconnect.
