1.4 Safety and ESD Notes

EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!

Standard ESD precautions must be taken when handling electronic equipment. The

78M6610+PSU contains ESD protected interfaces.

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

78M6610+PSU hardware. Damage to the 78M6610+PSU and external equipment will

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

78M6610+PSU’s V3P3 supply rail (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

10–240 VAC 10mA–20A 46–64Hz

1.5 Testing the 78M6610+PSU Boards Prior to Shipping

Before every 78M6610+PSU Kit is shipped, the following procedures have been performed at the factory:

• Full Calibration – Precise energy source equipment is used to calibrate the current, voltage, and ambient

temperature for both the 16-pin and 24-pin daughter cards

• Accuracy Test – A “bench” level test ensures the energy accuracy is within ±0.5%.
