3.6 Main Circuit Wiring
This section describes the functions, specifications, and procedures required to safely and properly wire the main circuit
of the drive.
NOTICE: Do not solder the ends of wire connections to the drive. Soldered wiring connections can loosen over time. Improper wiring
practices could result in drive malfunction due to loose terminal connections.

Main Circuit Terminal Functions
Table 3.1 Main Circuit Terminal Functions
Terminal Type Function Reference
R/L1
Main circuit power
supply input
Connects line power to the drive.
Drives with single-phase 200 V input power use terminals R/L1 and S/L2 only (T/
L3 must not be used).
42S/L2
T/L3
U/T1
Drive output Connects to the motor. 48V/T2

B1
Braking resistor Available for connecting a braking resistor or the braking resistor unit option. 59
B2
+1
DC reactor connection
These terminals are shorted at shipment. Remove the shorting bar between +1 and
+2 when connecting a DC reactor to this terminal.

Wire Gauges and Tightening Torque
Select the appropriate wires and crimp terminals from Table 3.2 through Table 3.4.
Note: 1. Wire gauge recommendations based on drive continuous current ratings using 75 °C 600 Vac vinyl-sheathed wire assuming ambient
temperature within 30 °C and wiring distance less than 100 m.
2. Terminals +1, +2, –, B1 and B2 are for connecting optional devices such as a DC reactor or braking resistor. Do not connect other
non-specified devices to these terminals.
• Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is
greater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following
formula to calculate the amount of voltage drop:
•
Line drop voltage (V) = 3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10
-3
• Refer to instruction manual TOBPC72060000 for braking unit or braking resistor unit wire gauges.
• Refer to UL Standards Compliance on page 388 for information on UL compliance.
