7.0 Power Terminals Designations and Ratings (Terminal Block TM1)
Depending on inverter ratings, the power terminals (TM1) can have one of three configurations. These are shown as
A), B), C) and D) in Fig. 7.1. Section 7.2 covers the electrical ratings and tightening torques of the terminals.
Do Not
over tighten terminal screws. (See Sec. 7.2)
Use the proper wire size for terminal connections.
Use proper termination techniques.
