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. 18
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.
13
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.

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. 30
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.

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
