3.3 Cable Selection
Wire connections should be as short as possible. Make sure that
suitable wires are chosen based on safety requirement and rating of
current. Small cross section will result in lower efficiency, less
output power and the wires may also become overheated and cause
danger. For selection, please refer to the following table.

Step 1. Please connect AC input cables, DC output cables, battery
charging cables, and RJ-45 communication cables(if used)
to the terminal blocks of this product.
Step 2. Make sure cables well connected, all are then feeds the AC
energy to the supply.
Step 3. After power-on, make sure LED indicates in green or orange,
mean normal operation. （LED status refer to Chapter 4.3） ing

3 4 . Battery Selection
Battery types: Lead acid or lithium ion batteries
Battery capacity: Please refer to the following table
Battery capacity recommendation
NOTE:
1
.
Using batteries with greater capacity than recommendation will not
damage the battery, but extend charging period is expected.
2
.
Please contact battery supplier for charging characteristics if it s '
not clear.
3 5 . Serial and parallel connection of battery
● : Serial connection When connect
2 batteries in series, it doubled
t h e o u t p u t v o l t a g e , b u t t h e
capacity remains.
EX: 2pcs of 12V 100AH in series,
become a 24V 100AH battery.
● Pa r a l l e l c o n n e c t i o n : W h e n 2
batteries connected in parallel,
output voltage remains, but the
capacity . becomes doubled
EX: 2pcs of 12V 100AH connect in
parallel,become a 12V 200AH
battery.
