1.4 Safety and ESD Notes

EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!

Do not connect test equipment or external development boards directly to the non-

isolated portion of the 78M6610 hardware. Damage to the 78M6610 and external

equipment will occur due to the 78M6610’s “high side” reference topology. The

78M6610’s V3P3 supply (i.e., “high side”) is connected directly to Neutral (Earth

Ground) creating a ground reference disparity with any properly grounded external

equipment.

The board components and firmware settings are designed to operate with the following nominal AC electrical

ranges:

Voltage Current Line Frequency

10-300 VAC 10 mA – 20A 46-64 Hz

1.5 Testing the 78M6610+LMU EV Board Prior to Shipping

Before every kit is shipped, the board (and sensors) undergo a single-load point calibration using precise

energy source equipment. The device temperature is also calibrated at the same time. Results printed out on

paper and included with the EV kit.
