3.2 ELECTRICAL INSTALLATION
DANGER!
The following information is merely a guide for proper installation. Comply with applicable local
regulations for electrical installations.
DANGER!
Make sure the AC power supply is disconnected before starting the installation.
3.2.1 Identification of the Power and Grounding Terminals
NOTE!
Models CFW110006B2 and CFW110007B2 may operate with two phases only (single-phase power
supply) without rated output current derating. In this case, the single-phase power supply may be
connected to two of any input terminals.
Models CFW110006S2OFA, CFW110007S2OFA, and CFW110010S2 only operate with single-
phase power supply. In this case, the single-phase power supply shall be connected to terminals
R/L1 and S/L2.
R/L1, S/L2, T/L3: AC power supply.
DC-: this is the negative potential terminal in the DC bus circuit.
BR: braking resistor connection.
DC+: this is the positive potential terminal in the DC bus circuit.
U/T1, V/T2, W/T3: motor connection.
