POWER WIRING
Input and output power connections are performed through a
ten position terminal block, TB1 (see page 2-3 for location).
Figure 2.6 Power Terminal Block Designations (TB1)
➀ Connection for Dynamic Brake Resistors for all models except the 200-230 Volt,
0.37 to 0.75 kW (0.5 to 1 HP) drive. Important: The [DB Enable] parameter must
be enabled for proper operation.
➁ For single phase applications, the AC input line can be connected to any two of
the three input terminals R, S, T (L1, L2, L3).
➂ 1305 drives are UL and cUL listed, and CSA certified as a motor overload
protective device. An external overload relay is not required
for single motor
applications. Important: This drive is not intended for use with single phase
motors.
➃ Ground from drive to motor frame must be an independent continuous insulated
wire run.
