If using a braking resistor or dynamic braking resistor unit, install a magnetic contactor.
15 Properly install the resistor, and ensure that overload protection shuts off the power
supply.
16 Verify phase advancing capacitors are NOT installed on the output side of the drive.
17 Use twisted-pair cables for all drive control circuit wiring.
18
Ground the shields of shielded wiring to the GND
If using a 3-wire sequence, properly set parameters for multi-function contact input
19
terminals S1 through S7, and properly wire control circuits.
20 Properly wire any option cards.
