Wire the Main Circuit Terminal Block

Wire the main circuit terminal block correctly as specified by the instructions in the manual.
To comply with UL standards on drive models 2257 to 2415, 4208 to 4720, and T208 to T720, use UL-approved
closed-loop crimp terminals. Use the tools recommend by the terminal manufacturer to crimp the closed-loop crimp
terminal. Refer to Closed-Loop Crimp Terminals on page 285

Notes on Wiring the Main Circuit Terminal Block
Read these notes before you wire the main circuit terminal block.
• Use UL-Listed, vinyl-coated insulated copper wires for operation with a continuous maximum permitted
temperature of 75 °C at 600 V.
• Remove all unwanted objects that are near the terminal block connections.
• Remove the insulation from the connection wires to the wire stripping lengths shown in the manual.
• Do not use bent or crushed wires. Remove the damaged end of the wire before you use it. Incorrect connections can
cause death or serious injury from fire.
• Do not solder stranded wire. Soldered wire connections can become loose over time and cause unsatisfactory drive
performance.
