Install the motor wiring away from other wire routes. Avoid long parallel runs
with other wires. A dedicated conduit should be provided from the drive to the
motor for the output wiring.
WARNING! Check the motor and motor wiring insulation before connecting
the ACH 400 to line power. Follow the procedure provided below. Before
proceeding with the insulation resistance measurements, check that the
ACH 400 is disconnected from incoming line power. Failure to disconnect
line power could result in death or serious injury.
For frames R1 through R4
Connect the output power to the terminals at the bottom of the bypass section
as shown in Figure 3-1. Connect the equipment grounding conductor to the
ground lug near the motor cable terminal block connection point.
For frames R5 through R9
Connect the motor cables to the output terminal block. The motor grounding
conductor can be connected to the ground lug. Figure 3-3 shows the
connection points for frames R5 through R6. For frames R7 through R9, refer
