battery pack can store and release electric energy based on the requirements
of inverter management system.
The battery pack, which is wall-mounted, consists of master control battery
pack (HEC2-MP69r1) and slave control battery pack (HEC2-SP69r1). The
master battery pack and slave battery pack are of the same size, but the
former is fitted with LED status indicator to show the current electric quantity,
running status and fault information.
2-Product Introduction
Avoid direct contact with the leaked liquid or gas of battery, for the
electrolyte is corrosive; otherwise, skin irritation or chemical burn may occur.
For any contact with leaked substances, please take the following measures:

3.2 Steps of Installation
The positioning rack attached in battery pack can be used for simple
positioning. Please use it along with the level gauge, in order to correct the
horizontal error. Once all racks are installed, the positioning board can be
removed.
As shown in picture below, the lock hole is arranged at the back of rack to
avoid accidental falling of battery pack. Please determine whether secondary
lock is required according to the accidental risks at site.
Once harness is installed, protect the unconnected communication ports of
battery pack with waterproof cap, cover and reset the top.
The PTC-OUTPUT and series-OUTPUT interface of the final slave battery
pack per cluster should be short-circuited by using F, G short-circuit piece.
Use harness H, C1, D1, E1 for connection, as shown in picture below:
Use harness C1, D1 and E1 for connection, as shown in picture below.
Please repeat this step is 1 master battery pack is fitted with 4 slave
battery packs (maximally).
The PTC-OUTPUT and series-OUTPUT interface of the final slave
battery pack should be short-circuited by using F, G short-circuit
piece, in order to form complete circuit of this electrical interface.
The ground clearance of battery pack should conform to the local laws and
regulations. When attached positioning board has conflict with the laws and
regulations, the laws and regulations shall prevail.
Keep slot upwards
Connect the rack B, positioning board C, D and E according to the
picture below. Determine the ground clearance of battery pack, the
drilling position for fixed bolts of 8 racks, and mark the drilling position
with marking pen.
Determine the rack position of the second battery pack according to the
picture below. Mark the drilling position with marking pen. Repeat the
steps in 1.2 to fix the rack of battery pack.
Please repeat this step to install multiple racks of battery pack.
Conduct drilling (hole depth ≥50mm) at the marked position by using
the φ12mm percussion drill and remove the positioning board E. Fix and
fasten the rack E by using M8*60 expansion screws. Not less than 2
expansion screws should be used per column (4-point fixing).
Positioning board C: Determine the inverter position. Positioning board
D: Determine the rack position of battery pack.
Note:
Make sure the slot faces upwards when installing the rack.
#1 installation positioning board: Applies to vertical positioning between
master control battery pack and PCS; applies to vertical positioning
between battery packs. between battery packs.
#2 installation
positioning board:
Applies to horizontal
positioning between
master battery packs.
#3 installation positioning board:
Applies to positioning between rack and
ground during installation on ground.
When 1 cluster of master battery pack system is used in the battery
system selected by user, the optional accessory 1 should be purchased,
and the inverter harness should be connected according to picture
below:

Covering pieces are arranged at top and both sides of battery pack. Choose
whether cover them after installation (covering is recommended).
The effect picture for product with the max. battery pack system and
completed installation is shown below: The top covering piece of battery pack
will be provided with semi-transparent treatment, in order to display the
installation effects of harness.
4.1 Hardware Setting
The machine can be started immediately after system installation, for the
battery pack has been configured before leaving factory.
4.2 Status Introduction
Once the battery pack is powered on, its status will be displayed and judged
by LED of master battery pack.
A total of 7 LED lamp beads are arranged at the upper left corner of master
battery pack panel
#1-#6 lamp: Current electric quantity; in which, #6 lamp: Red/blue lamp,
others are single-color lamps in blue.
#7 lamp: Current battery status; red/yellow lamp.
#1-5# lamp bead: The corresponding lamp beads will flicker during battery
charging, or they will be off progressively during discharging.
4-Product Debugging
#6 lamp bead:
Steady red: Battery pack is discharged to low battery level
(25%SOC>current electric quantity≥10%SOC), charge/discharge is
allowed;
Red light flashing: Low battery protection of battery pack, discharging is
disabled, please charge as soon as possible;
Red and blue flash alternatively: Charging at low battery (25%SOC>cur-
rent electric quantity≥10%SOC);
#7 lamp bead:
Off: Battery is running normally;
Steady red: Battery fault, charge/discharge prohibited
Blinking yellow: WIFI communication error, charge/discharge allowed
Note: When status indicator is steady red, the power status indicator will
become off completely!
When 2 clusters of master battery packs are used in battery system
selected by user, the optional accessory 1 and 2 should be purchased;
the parallel harness of two master battery packs and inverter connec-
