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.

15 Verify phase advancing capacitors are NOT installed on the output side of the drive. –
Control circuit wiring
16 Use twisted-pair cables for all drive control circuit wiring. –
17 Ground the shields of shielded wiring to the GND terminal. 52
18 If using a 3-Wire sequence, set parameters for MFDI terminals S1 through S7, and properly wire control circuits. 44
19 Check for any other wiring mistakes. Only use a multimeter to check wiring. –
20 Properly fasten the control circuit terminal screws in the drive. Refer to Table i.3 , Table i.4 , or Table i.5 . 46
21 Pick up all wire clippings. –
22 Ensure that no frayed wires on the terminal block are touching other terminals or connections. –
23 Properly separate control circuit wiring and main circuit wiring. –
24 Analog signal line wiring should not exceed 50 m. –
25 Safe Disable Input wiring should not exceed 30 m. –
