Electrical Wiring Diagrams - Mitsubishi Electric Lossnay LGH-50RVS-E Handbook

4. Electrical wiring diagrams

LGH-50RVS-E, LGH-80RVS-E, LGH-100RVS-E
* Wiring for TM1, TM2, TM3, TM4, and TB5 shown in dotted lines are field work.
* Be sure to connect the earth wire.
* An all pole electric leakage isolator must be installed.
* Always use an isolator for the main power connection.
