Installation - Pytes E-BOX Series User Manual

3.All power supply should be off.

5.4 Installation

5.4.1 Install the battery
The E-BOX SERIES can be installed either vertically or horizontally. In this chapter, instructions here
are only for horizontal installation such as: installation in a 19-inch cabinet. Vertical installation is similar.
All equipment must be placed steadily after installation.
5.4.2 Connect Ground cable
Unscrew the screw at the grounding hole on the front panel of the battery, wrap the ground cable around
the screw, and tighten it with a screwdriver. Connect the other end of the ground cable to a reliable ground
point.
Note: The grounding resistance should be less than 0.1Ω.
5.4.3 Connecting the power cable
Before connecting the power cable, connect and disconnect the cable to identify the positive and
negative terminal, then make a mark respectively. After the cable is connected, measure whether there
is a short-circuit or reverse connection.
Select the correct line based on your load by referencing to the table below：
AWG
(kcmil)
4 41.7
5 33.1
6 26.3
7 20.8
8 16.5
9 13.1
10 10.4
It should be > 6 AWG.
Connecting the power cables:
1)Power cable connection instructions of Single-Rack:
Single battery:
Connect the positive and negative poles of the battery to the positive and negative terminal of the DC
port of the energy storage inverter (or the junction box) with a red and black cable respectively.
Multiple batteries (Max number 8):
The connection of several batteries is only permitted in parallel. Firstly, connect the positive poles
with the red cables, and connect the negative poles with the black cables. Next connect the positive and
negative poles of the battery to the positive and negative poles of the DC port of the hybrid inverter (a
storage device or a junction box) with a red and black cable.
The standard charge/discharge curent of each single battery is the same no matter how many
batteries are paralleled refer to the "Table1-1". Bus bar should be applied when higher current (>100A)
is needed for specific projects.
The capacity can be increased by connecting the batteries in parallel, but due to the limitations of
BMS and power cable, Max. 8 batteries can be connected in parallel as a group without any additional
kits and a bus bar should be used for connecting them together.
