Check drive model number to ensure receipt of correct model.
Drive, Peripherals, Option Cards
2
Make sure you have the correct peripheral devices.
3
Check the option card model number.
Installation Area and Physical Setup
4
Ensure that the area surrounding the drive complies with specifications.
Power Supply Voltage, Output Voltage
5
The voltage from the power supply should be within the input voltage specification range of the drive.
–
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.
8
Power supply voltage of models 4
o
0477 to 4
o
0930 should not exceed 480 V when connecting with recommended EMC filters.
Main Circuit Wiring
9
Confirm proper branch circuit protection as specified by national and local codes.
10
Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3.
11
Properly wire the drive and motor together.
The motor lines and drive output terminals U/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.
12
Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. Wire gauge recommendations based on using
75 °C (167 °F), 600 Vac vinyl-sheathed wire.
13
Use the correct wire gauges for the main circuit.
• 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.
14
Properly ground the drive.
15
Tighten control circuit and grounding terminal screws.
16
Set up overload protection circuits when running multiple motors from a single drive.

o
0930, and terminals p2 and n2 of the harmonic filter module.
22
The cable between drive models 4

0930 and harmonic filter module should not exceed 5 m (16.4 ft.).
23
The resistance value between the terminals R/L1, S/L2, and T/L3 of the harmonic filter module should exceed 1000 Ω when connected to drive
models 4
o
0720 to 4
