5. Attach permanent labels 20 mm from both ends of each power cable.
6. Use cable ties to bundle cables every 150 mm upwards from the bottom and
fasten the cables to the cable tray.
To ensure that the power cable is long enough, perform the following steps to install a
power cable:
1. Prepare a power cable a little longer than the distance between the power module and
PDF.
2. Install a terminal on one end of the power cable and connect the terminal to the device.
To facilitate power cable routing, it is recommended that the power cable is connected
only to power jack A on the right of the power module, as shown inFigure2.
3. Connect power cables to the positive and negative electrodes securely. Otherwise, the
power test result is inaccurate.
4. Route the power cable, bind it to the cable tray, and cut any excess length of the cable.
Install a terminal on the other end of the power cable and connect the terminal to the
PDF.
