*1 The wire gauges for drive models 4810 to 4H12 are the recommended wire gauges when you use these drive models as a 6-Phase/12-
Pulse drive.
*2 Remove insulation from the ends of wires to expose the length of wire shown.
*3 When you use drive models 4810 to 4H12 as a 6-Phase/12-Pulse drive, remove the common bus bars on the input terminals.
*4 When you connect a braking unit (CDBR-type) to terminals - and +3, refer to Braking Unit Connection Wire Gauge (CDBR-Type) on
page 51 .
Braking Unit Connection Wire Gauge (CDBR-Type)
To comply with IP20 when you connect a braking unit (CDBR-type) to drive models 2257 to 2415, 4208 to 4720, or
T208 to T720, refer to
Table 7.3 , Table 7.4 , and Table 7.5 to select the wires.
