Drive, Peripherals, Option Cards
1 Check drive model number to ensure receipt of correct model. 34
Drive, Peripherals, Option Cards
2 Make sure you have the correct peripheral devices. 458
3 Check the option card model number. 458
Installation Area and Physical Setup
4 Ensure that the area surrounding the drive complies with specifications. 58
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.
34
7 Verify that the drive is properly sized to run the motor.
8
Power supply voltage of models 4o0477 to 4o0930 should not exceed 480 V when connecting with recommended EMC filters.
78
Main Circuit Wiring
9 Confirm proper branch circuit protection as specified by national and local codes. 78
10 Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3. 83
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.
98
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. 105
15 Tighten control circuit and grounding terminal screws. 98

17
Verify that ground wiring for models UUoEoooo and UUoWoooo is correct before turning on the EMC filter switch.
–
18 Verify phase advancing capacitors, input noise filters, or GFCIs are NOT installed on the output side of the drive. –
19
Properly wire the power lines to terminals X, Y, and Z of drive models 4o0720 to 4o0930, and terminals X, Y, and Z of the harmonic filter module.
96
20
Properly wire the power lines to terminals X1, Y1, and Z1 of drive models 4o0720 to 4o0930, and terminals X1, Y1, and Z1 of the harmonic filter
module.
21
Properly wire the power lines to terminals p2 and n2 of mdrive models 4o0720 to 4o0930, and terminals p2 and n2 of the harmonic filter module.
22
The cable between drive models 4o0720 to 4o0930 and harmonic filter module should not exceed 5 m (16.4 ft.).
96
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 4o0720 to 4o0930. If the resistance value does not exceed 1000 Ω, check for main circuit wiring mistakes between the harmonic filter
module and drive models 4o0720 to 4o0930.
