to the load. If an electronic load is going to be used pay attention to the right polarity: the (+)

output terminal is that located closer to the corner.

Warning:

Like in any offline circuit, extreme caution must be used

when working with the application board because it contains

dangerous and lethal potentials.

The application must be tested with an isolation transformer

connected between the AC mains and the input of the board

to avoid any risk of electrical shock.
