Preparing Ac/Dc Cables - Delta 100kW PCS Installation Manual

Preparing AC/DC Cables

The following guidelines describe how to prepare the AC/DC cables for a grid connection.
When crimping 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, which is available from the
accessory kit.
2. Continue inserting the cable until its head reaches the wire inspection indicator, as shown in the
following figure:

3. For safety purpose, use heat shrinkable tubing on the junction between the cables and lugs. The
voltage rating of the heat shrinkable tubing should be at least 1000 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:
