Drive, Peripherals, Option Cards
1 Check drive model number to ensure receipt of correct model. 31
2 Make sure you have the correct braking resistors, DC link chokes, noise filters, and other peripheral devices. 376
3 Check the option card model number. 376
Installation Area and Physical Setup
4 Ensure that the area surrounding the drive complies with specifications. 48
Power Supply Voltage, Output Voltage
5 The voltage from the power supply should be within the input voltage specification range of the drive. 191
6 The voltage rating for the motor should match the drive output specifications.

7 Verify that the drive is properly sized to run the motor.
Main Circuit Wiring
8 Confirm proper branch circuit protection as specified by national and local codes. 68
9
Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3.
Note: Confirm the following when wiring models 4A0930 and 4A1200:
• Remove the jumpers shorting terminals R/L1-R1/L11, S/L2-S1/L21, and T/L3-T1/L31 when
operating with 12-pulse rectification. Refer to 12-Pulse Rectification on page 73 for details.
• When operating without 12-pulse rectification, properly wire terminals R1/L11, S1/L21, and
T1/L31 in addition to terminals R/L1, S/L2, and T/L3.
71
10
Properly wire the drive and motor together.
The motor lines and drive output terminals R/T1, V/T2, and W/T3 should match in order to produce the desired phase
order. If the phase order is incorrect, the drive will rotate in the opposite direction.
93
11 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 85
12
Use the correct wire gauges for the main circuit. Refer to Main Circuit Wire Gauges and Tightening Torques on page
85 .
• 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 × wire resistance (Ω/km) × wire length (m) × current (A) × 10

• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency set to C6-02 accordingly.

Tighten control circuit and grounding terminal screws. Refer to Main Circuit Wire Gauges and Tightening Torques on
page 85 .

Install a magnetic contactor when using a dynamic braking option. Properly install the resistor and ensure that overload
protection shuts off the power supply using the magnetic contactor.
382
17 Verify phase advancing capacitors, input noise filters, or GFCIs are NOT installed on the output side of the drive. –
Control Circuit Wiring
18 Use twisted-pair line for all drive control circuit wiring. 98
19 Ground the shields of shielded wiring to the GND terminal. 98
20 For 3-Wire sequence, set parameters for multi-function contact input terminals S1 – S8, and wire control circuits. –
21 Properly wire any option cards. 98
22 Check for any other wiring mistakes. Only use a multimeter to check wiring. –
23
Properly fasten drive control circuit terminal screws. Refer to Main Circuit Wire Gauges and Tightening Torques on
page 85 .
