Connecting Power Cables
Context
- The unit must be grounded as required by local electrical specifications.
- Cables must be routed in through cable clips.
- Route and bind the cables along the beams or columns of the unit.
- The neutral wire is not required for the power input to the product. Cut the blue neutral wire onsite and wrap the exposed part using insulation tape.
- Select appropriate holes for routing cables based on the onsite cable routes.
- In the example, the equipotential ground cable is routed from the top of the cabinet. In the bottom cabling mode, the ground cable is routed through the cabinet bottom.
Procedure
- A ground cable must be routed from the equipotential ground point of the unit to the ground. The following figure shows the equipotential bonding point of the unit.Figure 4-23 Equipotential ground point (using top cabling as an example)
- Connect wiring terminals of the L1, L2, and L3 wires of the input power cable respectively to the corresponding terminals of the external power cable.
- Connect the PE cable to the cabinet ground screw, as shown in the following figure.
Exercise caution while connecting cables. Prepare protective tools in advance.
