1.Equipment Introduction
The POWER BOX is mainly applied and developed for the renewable energy
generation system compatible with lead-acid batteries and lithium-ion batteries. It
helps to achieve the optimal usage of renewable energy. The POWER BOX can
control the bi-directional flow of electric power, work under the auto / manual
mode and time-of-use (TOU) price mode, automatically controls the PowerCube
2.0 charge / discharge. The POWER BOX control features will store renewable
energy as well as grid power in PowerCube 2.0 & discharge the PowerCube 2.0 to
supply power to the load.

2.Equipment Safety Notes
Before the inverter is used, please read all instructions, warning signs and this
manual. The inverter strictly meets safety rules of design and testing. Operators
should abide by safety regulations during installation, operation and
maintenance. Any improper operation may cause an electric shock or damage
the equipment and properties.

2.1 Safety Signs
2.2 Safety Notes
Electrical installation and maintenance must be carried out by competent
electricians according to national connection rules.
The POWER BOX must be installed only by qualified technical personnel, and
only after receiving appropriate approvals, as required by the local authority
having jurisdiction.
The PowerCube 2.0 should keep a certain distance with the POWER BOX and
protected well to prevent from any collision.
It is forbidden to place explosives and combustibles, e.g. gasoline, kerosene,
oil, slab, cotton and rag, etc. around the POWER BOX.
To avoid electric shock, the input of PowerCube 2.0 and AC output of the
inverter should be shut down for at least 5min. before installation or
maintenance.
The temperature of some parts of the inverter may exceed 60℃. The inverter
shall be cooled down in order to avoid getting burnt during the maintenance.
Children should not go near the inverter.
Please do not open the external cover of the inverter without permission,
except for installation/maintenance. Without following proper
installation/maintenance procedures, someone could be injured and/or even
damage the inverter.

Static power may damage electronic elements. Please neutralize the static
first to avoid damage to the inverter which could void warranty.
The warranty may be void if the equipment is damaged because it is not
operated according to the operation method of the specified manufacturer.
To completely isolate the inverter: - The first step is to shut down the DC switch
and followed by disconnecting the PowerCube 2.0 and the AC terminal.
The POWER BOX shall be isolated and shut down completely before
conducting any maintenance. The inverter must not be maintained in any
other modes!
It is FORBIDDEN to disconnect the PowerCube 2.0 terminal and the AC
terminal when the POWER BOX is running.
2.3 PowerCube 2.0 Installation and Maintenance
Notes
PowerCube 2.0 has been charged before delivery and should therefore be
prevented from short circuit during transportation and installation.
PowerCube 2.0 shall be placed in a well-ventilated space. Do not install the
PowerCube 2.0 in airtight or badly ventilated spaces.
Do not place the PowerCube 2.0 in high-temperature situations, direct
sunshine or in front of a furnace or fire to prevent PowerCube 2.0 from circuit
leakage causing fire and/or explosion.
The connection cable shall be as short as possible to avoid significant voltage
drop.
Before connecting the terminal for PowerCube 2.0 system, check the anode
and cathode of the PowerCube 2.0 system to ensure correct installation.
If it becomes necessary to store PowerCube 2.0, the system needs to be
isolated from the DC terminal and be disconnected from Power Box and load.
It should be stored away in a cool, dry and ventilated environment.
Please take precaution when conducting the following:
The maintenance operators shall have the know-how and technical skill for
the maintenance of the PowerCube 2.0;
When the battery is changed, the battery of the same model and quantity
shall be changed. It may be necessary to switch out the entire array of
batteries to avoid significant battery system loss due to mismatch;

Warning: Do not dispose the scrap batteries directly to fire. Such disposal may
cause the batteries to explode.
Warning: Do not dismantle the PowerCube 2.0. Its electrolyte may be toxic
and direct contact could cause serious irritation to skin and eyes and/or
worse personal injuries.
Warning: PowerCube 2.0 may cause an electric shock or short circuit when
mishandled. Please take the following measures before and during operation
of PowerCube 2.0:
a) Do not wear watch, ring or any other metal objects.
b) Use tools with insulated handles.
c) Wear rubber gloves and shoes.
d) Do not put tools and metals above the PowerCube 2.0.
e) Switch off the power supply mode before the PowerCube 2.0 terminal is
connected.
f) Ensure PowerCube 2.0 is not installed too close to the ground or connecting
components like cables and terminals touches or installed too close to the
ground. Having the system or connecting components too close to the
ground may cause trip over or accidental pull off disconnections causing
electric shock!

3.5 Installation Position
The POWER BOX should be vertically mounted (to ensure proper heat dissipation),
please choose a position without direct sunlight / snow accumulation to install the
POWER BOX.
Fig. 4 Installation Position of POWER BOX
3.6 Mounting
Step 1: Put the mounting bracket on the wall and mark the 8 drill holes by using a
marker pen. Drill 8 holes (drill bit 6mm) on the wall.
Step 2: Insert the wall plug vertically into the hole, note the insertion depth. (Not
too shallow or too deep)
Step 3: Fix the mounting bracket on the wall by using screws & flat washers.
Step 4: Put the POWER BOX on the mounting bracket.
Step 5: Ground the POWER BOX by using the grounding hole on the heat sink.
Step 6: OPTIONAL: you can lock the POWER BOX

4.Electrical Connection
Be aware of electric shock and chemical hazards!
Before connecting the PowerCube 2.0, ensure the cable connectors have
the correct polarity. Reversed polarity will damage the inverter!
Before connecting the PowerCube 2.0, please make sure that the
PowerCube 2.0 isolator is off; ensure the inverter can be disconnected
securely during maintenance.
Before connecting to Grid, please install a separate AC breaker (20A)
between POWER BOX and grid. A double pole AC breaker will be required to
connect critical load to the POWER BOX as well.
It is very important for system safety and efficient operation to use appropriate
cable for electrical connection.
PowerCube 2.0 connection: cable of AWG8 (10mm2) or AWG6 (16mm2).
Grid & Load connection: cable of AWG12 (4mm2).
Make sure N wire is connected to PE wire when the POWER BOX is working in
EPS (Emergency Power Supply) mode.

4.4 Load Connection
Critical load: in case of grid outage, the POWER BOX will work in EPS (Emergency
Power Supply) mode, discharge the PowerCube 2.0 & supply power to critical
load via LOAD port.
LOAD port is only for critical load connection. Please make sure that you’ve
purchased the AC contactor accessory from Trinabess .
The connection procedure to LOAD port is the same as grid connection (Fig. 10).
Before connecting the critical load, please make sure that you understand the
following diagram (Fig. 11).
