Field Wiring Terminal: Use Copper Conductors Only, 60/75℃, 12-24 AWG torque value 7 lb-in. Terminal Block + 10 - 48VDC PW1 - Power Ground + 10 - 48VDC PW2 - Power Ground Earth Ground Relay Output 1A @ 24VDC 1. The relay contact opens if Power1 or Power2 falls 2. The relay contact opens if the Port Link is broken (When Link Down Detection is enabled) IES-0920 User Manual Page 9
