However, the FR-CS82S is not equipped with terminal T/L3. (Phase need not be matched.) Never connect the power cable to the U, V, and W of the inverter. Doing so will damage the inverter. • Connect the motor to U, V, and W. (The phases must be matched.) 31 2. INSTALLATION AND WIRING 2.5 Main circuit terminals Terminal symbol Terminal name Terminal function description Refer to page Connect these terminals to the commercial power supply.
Do not connect anything to these terminals when using the high power R/L1, S/L2, T/L3 AC power input — factor converter (FR-HC2) or the power regeneration common converter (FR-CV). U, V, W Inverter output Connect a three-phase squirrel-cage motor to these terminals. ― Connect the brake unit (FR-BU2), power regeneration common P/+, N/- Brake unit connection converter (FR-CV), or high power factor converter (FR-HC2) to these 42 terminals.
