WARNING
Observe all safety rules when working with high voltages or line voltages. Connect the (GND) terminal to earth ground in order to maintain the case at a safe voltage.
Whenever hazardous voltages (>45 V) are used, take all measures to avoid accidental contact with any live components: a) Use maximum insulation and minimize the use
of bare conductors. b) Remove power when adjusting switches. c) Post warning signs and keep personnel safely away.
