Preparing AC/DC Cables
The following guidelines describe how to prepare the AC/DC cables for a grid or battery
connection. When crimping a cable, a hexagonal crimping method is recommended.
1.
Strip the head of the insulator of the AC and DC power cables. Insert the exposed part of the
power cable into the junction hole of the corresponding cable lug.
2.
Continue inserting the cable until its head reaches the wire inspection indicator, as shown in the
following figure:
Figure 20. Inserting a Power Cable into a Cable Lug, Depth Reference Diagram
3.
For safety purposes, use heat shrinkable tubing on the junction between the cables and lugs. The
voltage rating of the heat shrinkable tubing should be at least 1500 V for DC power cable or 600
V for AC power cable. Make sure the exposed part of the junction between the cables and lugs
is fully covered by the tubing, as shown in the following figures.
4.
Prepare the cables as follows:

Type B

Note:
We recommend two-hole lugs for cable connetion, but in some cases if customer want to use
single-hole lugs, the lug type and connection way should meet local standard and regulation.
