4-6 Power Wiring
MN766
4.9 Incoming Power and Motor Connections
Figure 4-3 shows the layout of the terminals on the power connectors for each size drive. All cables must be in conduits
or shielded and the conduits or shields must be grounded at the cable entrance. The brake resistor and cable must be in a
conduit or shielded if installed outside the enclosure.

Note: An open circuit between TH1 and TH2 will cause an overtemperature fault.
Refer to fault/troubleshooting information in Chapter 9.
Motor GND
1. Access the Power and Motor Terminals (see Cover Removal procedure).
2. Feed the power supply and motor cables into the drive through the cable entrance.
3. Connect the line L1, L2, L3 and GND to the power terminal connectors, Figure 4-4.
4. Connect motor leads to T1, T2, T3 and GND motor terminal connectors.

2. Use same gauge wire for Earth ground as is used for L1, L2
and L3 for AA, B, C frame drives. For D frame drives, size the
grounding conductor per the local electrical codes.
3. Metal conduit should be used. Connect conduits so the
use of a Reactor or RC Device does not interrupt EMI/RFI
shielding.
4. See Line/Load Reactors described previously in this section.
