question 1. Which measure is correct for resetting trip of EMPR: a) by once pressing button "Test/Reset"; b) resupply power of EMPR? But when we're try to reset trip by resupply power, the configuration of date is reset too. Instruction illustrate the electric scheme that show us the interrupting of supply power by "OFF/RESET" button. What the reason is of interrupting power supply of EMPR?
