Wiring
Grounding
•
The Drive must be solidly grounded using the main circuit ground terminal
•
If Drive is installed in a cabinet with other equipment, ground leads for all equipment should be connected to a
common low-impedance ground point within the cabinet.
•
The supply neutral should be connected to the ground point within the cabinet.
•
Select appropriate ground wire size from Table 1-1.
•
Make all ground wires as short as practical.
•
NEVER ground the Drive in common with welding machines, or other high power electrical equipment.
•
Where several Drives are used, ground each directly to the ground point (see Figure 1-2). DO NOT FORM A
LOOP WITH THE GROUND LEADS.
•
When connecting a motor to the Drive's output terminals, include a separate ground wire. Attach ground wire
solidly to motor frame and to Drive's ground terminal
•
When using armored or shielded cable for connection between Drive and motor, solidly connect armor or shield
to motor frame, and to the Drive's ground terminal
