WARNING
Observe all safety rules when working with high voltages or line voltages. Connect the (G) 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 ins
ulation and minimize the use of bare conductors.
b) Remove power when adjusting switches. c) Post warning signs and keep personnel safely away.
