Safety Precautions
Please comply with the following items for safe use:
oThis system uses special power supply units, therefore its installation and maintenance must
be done only by authorized technicians.
oDuring the installation of the Server, the distance between the equipment and wall must be at
least 300 mm for ventilation and heat dissipation from the system.
oThe temperature of the surface of the cabinet may rise to approximately 50 C, therefore care
must be taken always before touching the surface to prevent injuries.
oSince the storage is external, care must be taken to ensure that the voltage of the storage
bank meets the requirements of the rated voltage of the Server. Under no circumstances
should a storage bank be connected to the Server with different DC voltage settings than
those required by the Server.
oDo not open the cabinet of the Server, otherwise it will cause an electric shock. The internal
inspection and maintenance should be conducted only by authorized technicians.
oAfter the machine is turned off, its voltage may still be high for a long time, do not open
the cabinet to prevent electric shocks.
oThe “Manual Bypass” switch is used for maintenance and repair of the Server, which can be
performed only by authorized technicians.
oThis system is provided with multiple PV inputs, therefore it should be connected with
the independent loop, without the electrode grounded.
oThe "EPO" button on the panel is used for emergency stop power supply (power off) of the
Server, please pay attention to its operation.
oThe internal short circuit of the Server may lead to the risk of an electric shock or a fire,
therefore, under no circumstances should any form of liquid be placed on the product to
prevent electric shock or other hazards.
oIf the Server malfunctions, please cut off the power supply quickly and contact an
authorized technician.
oDo not store or use the Server in the following locations:
Outdoor;
Without cross-ventilation or are dusty;
Near combustible gas or corrosive substances;
With unusually high or low temperatures (±40 ℃) or with high humidity (>90%);
In direct sunlight or near heating appliances;
oPlease install and use dry powder fire extinguishers. Under no circumstances should a liquid fire
extinguisher ever be used.
oThe external power switch should be installed near the Server so that the power supply can be cut
off in an emergency.
Warning!
1. The Server must be reliably grounded when it is connected to the AC load.
2. Improper operation can be harmful and cause substantial loss, therefore, please follow
instructions and ensure that only authorized technicians work with the Server.

Unpacking Inspection
When unpacking the case of the Server, please make the inspections as follows:
1.
Take a visual inspection to make sure that there is no deformation, damage and
dislocation or other damage in transportation on the internal or external surface of the
Server and the battery. If there is any damage, do not install or use the system, please
notify Kilowatt Labs, Inc. immediately.
2.
Check the technical data sheet of the product to confirm whether it is the right
equipment. The technical data sheet of the Server is located on the label on the
internal side of the front door, with the model, capacity and main parameters of the
Server indicated on the label.
2.4 Determination of Mounting Positions
Please pay attention to the following requirements for the selection of the Server’s
installation space:
1. This Server must be installed in a clean and dry room (the environment temperature
within 0 ~ 40℃, the relative humidity of 5% ~ 90%, and the optimal operating
temperature of 25℃). If the room temperature is 40 ℃, the indoor exhaust fan should

17
be installed to ensure sufficient air flow in the room so that the equipment gets
adequate heat dissipation in case of rise in room temperature. In hot environments, it
is best to install an air-conditioner.
2. To facilitate wiring, daily maintenance, diagnosis, and repair of the Server, please make
sure the safe space of the front and the back doors is reserved (advisable space is 1000
mm or more to ensure that the door of the Server can be fully opened, and the
technicians can pass the freely).
Wall

1. The altitude is less than 1000 meters, otherwise, the derating of Server should be
used.
2. In the environment the bearing capacity should be greater than the equipment
weight (The equipment weight is as shown in the technical specifications).
2.5 Cabinet Handling
Please remove the surrounding rat proof baffles below the machine at first, and then get
the mechanical arms of the special handling equipment (hoisting equipment, stackers or
forklift) with the sufficient lifting capacity (please see Table 4 for the total weight of the
Server) stretched into the bottom of the base of the equipment. When the mechanical arms
are stretched into the base in place, jack up the equipment and then place it in the
predetermined installation location.

2.6Incoming Line Way of System
The incoming lines of the Server is the lower wiring pattern. When wiring, open the front
door of the Server, unpack the downside baffle, you can view the connection bar connected
with the power cable.
2.7Requirements of External Distribution
To guarantee reliable operation of the Server, please make sure that the power of
the external power supply should be more than 1.5 times of the equipment’s rated
power and the rated current of the power circuit breaker supply nearby the supply
equipment should be more than 1.2 times (not the switch with one grade higher
than the breaker) of that of the air switch of the equipment itself (RECTIFIER or
BYPASS).

The "BYPASS INPUT" and "AC INPUT” power supply system of the equipment should
be equipped with the separate "Circuit Breaker" or "Over-current Protection Switch” in
order to improve the reliability of the system.

The external power switch should be installed near the system to cut off the power
supply in an emergency.

CENTAURI ENERGY SERVER User Manual - Model 30-2017/12/18-VERSION 1.0
19
Special notes: Because there is the filter capacitor of the RFI filters to earth, which may
generate some leakage current, therefore the leakage protection switch should not be
used for the Server power supply in this system in case of false triggering protection of the
device.
2.8Power Cable
In the design of external connecting cables, the following factors should be considered: the
current capacity of power cable, requirements of the system overload capacity, the
environment temperature and physical support media. Based on this, suggested connection
cable’s cross-section dimensions are indicated in Table 12. This serves as a reference only,
and qualified installation engineers should make the appropriate selection about local
related standards and Table 12. The length of the connecting cables should be around 2~10
meters. Longer cable lengths lead to low voltage and therefore cross-section area of the
corresponding cable should be increased.
