  2. mMINT Communication Wiring Modbus RTU Network Master RS-485 Modbus SW3 should be moved to the ON position only when it is the last device in a chain of devices or if it is a single device. A Tx/Rx + Tx/Rx - B GND* SHD *) Connect shield to ground at master device end only. Interconnect shielding where devices are daisy-chained. (For diagnostics) SW1 should be moved to the ON position only when it is the last device in a chain of devices or if it is a single device. IZM26 Integrated -Status (on/off) sensors -Shunt trip and spring release control only available with Digitrip models 1150x **) for diagnostic mode, to configure the mMINT Feed control voltage to A14 and A15 for breaker remote control and for Trip Unit operation without current flow. Terminal B1 Terminal B2 +, P 0V, N INCOM +, P Terminal A14 0V, N Terminal A15
