3.12 Wiring Checklist
No. Item Page
Drive, peripherals, option cards
1 Check drive model number to ensure receipt of correct model. 17
2 Check for correct braking resistors, DC reactors, noise filters, and other peripheral devices. 52
3 Check for correct option card model. 279
Installation area and physical setup
4 Ensure area surrounding the drive complies with specifications. 26
Power supply voltage, output voltage
5 The voltage from the power supply should fall within the input voltage specification range of the drive. 83
6 The voltage rating for the motor should match the drive output specifications.
17
, 75
Main circuit wiring
7 Confirm proper branch circuit protection exists per National and Local codes. 34
8 Properly wire the power supply to drive terminals R/L1, S/L2 and T/L3. 36
9
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.
42
10 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 41
11 Use the correct wire gauges for the main circuit. Refer to Table 3.2 , Table 3.3 , or Table 3.4 . 41
• When using comparatively long motor cable, calculate the amount of voltage
drop.
3 x voltage resistance (Ω/km) x cable length (m) x motor rated current (A) x 10
-3
Motor rated voltage (V) x 0.02 ≥
41
• If the cable between the drive and motor exceeds 500 m, adjust the carrier frequency (C6-02) accordingly. 43 , 75
12 Properly ground the drive. Review page 43. 43
13
Tightly fasten all terminal screws (control circuit terminals, grounding terminals).
Refer to Table 3.2 , Table 3.3 , or Table 3.4 .

Note: Close MC1 through MCn before operating the drive.
15
If using a braking resistor or dynamic braking resistor unit, install a magnetic contactor. Properly install the resistor, and ensure that overload protection
shuts off the power supply.
52
16 Verify phase advancing capacitors are NOT installed on the output side of the drive.
Control circuit wiring
17 Use twisted-pair cables for all drive control circuit wiring. 44
18
Ground the shields of shielded wiring to the GND terminal.
48
19 If using a 3-wire sequence, properly set parameters for multi-function contact input terminals S1 through S7, and properly wire control circuits. 35
20 Properly wire any option cards. 279
21
Check for any other wiring mistakes.
Only use a multimeter to check wiring.
-
22
Properly fasten the control circuit terminal screws in the drive.
Refer to Table 3.2 , Table 3.3 , or Table 3.4 .
41
23 Pick up all wire clippings.
24 Ensure that no frayed wires on the terminal block are touching other terminals or connections.
25 Properly separate control circuit wiring and main circuit wiring.
26 Analog signal line wiring should not exceed 10 m.
27 All other wiring should be less than 50 m.
