REMARKS
a. Do not touch the hot part, or the hot and cold parts at the same time, as you are liable to a shock hazard.
b. Do not short circuit the hot and cold circuits as electrical components may be damaged.
c.
Do not connect an instrument, such as an oscilloscope, to the hot and cold circuits simultaneously as this may cause
