l Cable lugs are required for the PE wire.
¢ For MA01c–MA02c, recommended cable lug for PE wire is JST 8-4 (solderless terminals ring tongue).
For details on power connector sizing, see 4.4 Power Connectors. The dimensions apply to both solid and stranded cables.
7.9.2 Torque Requirements
Connections must be tightened with the correct torque, see the following table.

7.10 Electrical Installation
7.10.1 Mains, Motor, and Grounding Connection
The mains, motor, and grounding connection for single-phase and 3-phase drives are shown in Figure 46andFigure 47. Actual
configurations vary with unit types and optional equipment.
 NOTICE
In motors without phase insulation, paper, or other insulation reinforcement suitable for operation with voltage supply, use a
sine-wave filter on the output of the drive.
