Important Safety Instructions
Please read this manual thoroughly before putting the equipment into
operation. Pay regard to the following safety instructions and keep this
manual nearby for future purpose.
INITIAL OPERATION
This operating manual is based on the state of technology at the time of
printing. However, it is possible that despite regular control and correction, the
present document contains printing errors or deficiencies. Nanjing Bridge New
Energy Technology Co.,Ltd assumes no liability for any technical, printing or
translational errors within this manual.
UNPACKING
Please make sure that the shipping carton and the packaging is free of
damage. If external damage is found, it is important to record the type of
damage. Please keep the original packaging to ensure the device is
adequately protected in case it needs to be transported in the future or claims
for compensation need to be asserted.
SETTING UP
To avoid electric shocks and product failure, the device should be installed in a
temperature and humidity controlled indoor environment. The ambient
temperature must not exceed 40℃. The device must never be exposed to
liquids or extreme humidity.
VISUAL INSPECTION
The unit must be examined immediately for defects or damages in transit.
Damage caused during transport may be loose or broken control knobs and
bent or broken connectors. Do not use the device if any physical damage is
apparent. Please inform the carriers and a representative of Bridge
Technology immediately.

MAINS OPERATION
Make sure to verify the model number and voltage stated on the nameplate.
Damages due to wrong power feed are not covered by guarantee conditions.
CAUTION
The unit must only be operated when connected directly to the mains.
To avoid damage, do not connect the unit to isolating transformers,
autotransformers, magnetic current limiters or similar devices.
INTENDED USE
The device corresponds to protection class I and has a galvanic isolation
between the input and the output circuit. The device must be grounded on the
input side, since the grounding ensures protection against contact. In the case
of locally variable devices, the earth is connected to the device by means of a
cold-plug connector, and the ground is connected to the screw terminal
provided for locally-variable devices (screw contacts at the grid input). In the
case of devices with high leakage current (marking on the device), the existing
grounding bolt must additionally be connected to the domestic installation
earth. For compliance with the EMC and safety regulations (CE, approvals),
the device may only be operated with PE connected. The device may only be
operated by trained personnel and in accordance with the instructions for use.
Typical fields of application are laboratories, industry and service engineering.
Applications which can lead to injuries or death in the event of a fault in the
device are not permitted.

1.6 Connect to Power
ESA series power source supports the world grid standards, but a particular
product supports the GRID SYSTEM only for one country or region. Before the
power supply is used, it is necessary to verify that the product specifications
are consistent with the Local GRID. And please connect the power following
the steps below.
1.6.1 Check the input power
Make sure that specifications of the power source are consistent with the local
GRID, such as voltage and frequency.
1.6.2 Check the fuse
When the product leaves factory, the specified fuse is installed. Please check
whether the fuse matches the actual input voltage according to the "Input
Power Requirements" at the rear panel of the product.
1.6.3 Cable selection
The user should select the appropriate cable and cold-pressed terminal
according to the equipment's input/output voltage level and current, and crimp
the grid side AC input cable and the AC output cable.
1.6.4 Connect the AC power
Connect the power source to AC power supply with proper specification cable
according to the product specification within the local country could be used.
Wiring methods refer to the following steps.
A. Remove the bottom baffle after opening the front cabinet door. The user
can access the grid side incoming line, earthing protection wire PE, the

16

positive and negative poles on the DC side into the cabinet through the
threading holes at the bottom of the cabinet (marked in red in Figure 1-6),
and reliably connect with the terminal/wire copper bar.
Figure1-6 Holes for cables Figure1-7 The wiring copper bar
B. Lay the PE cable from the cable hole at the bottom of the cabinet and
reliably connect with the connection copper bar shown in Figure 1-7, and
ensure both side of PE cable are well grounded. The grounding terminals
are connected with the main components, and the users should connect
them with the earth through suitable cables before putting them into use.
C. The AC incoming line (L1/L2/L3/N) and the positive and negative
terminals/copper bar on the DC side are shown in figure 1-8. After the
cables are threaded through the holes at the bottom, it is connected to the
terminal block/wiring copper bar. After the connection is completed, the
phase sequence and connection reliability should be carefully checked to
Warning
For safety reasons, the grounding protection PE must be
connected reliably.

17
www.bripower.cn
ensure that the phase sequence is correct, the connection is reliable, and
the identification is clear to facilitate maintenance and repair in the future.

Connection terminals
1.7 Power on Inspection
1.7.1 AC Input power on
After the cable connection is completed, the circuit breaker on the grid side
could be turned on (as shown in Figure 1-9). It should be noted that the input
connection is 3P+N, and the correct phase sequence must be confirmed.
1.7.2 Control module power on
After power-on for grid side, open the cabinet door, close the power switch of
the control module shown in Figure 1-10 (②), then the control unit starts to
work. After completing these operations, close the cabinet door, and the power
supply will enter standby state.
Warning
Before connecting the cable, make sure that the upper switch is in
the off state. Live work is strictly prohibited. At the same time,
ensure that a reliable protective grounding has been made.

1.8 User Interface
The GUI software is installed in the touch panel, which is in fact a computer
with Microsoft Windows. The software can also be installed in control PC
connected to power supply. The GUI software provides functions including
output settings, island test settings, protection parameter settings, waveform
display, measurement display and faults display.
Also, the power source can be controlled in local and remote style. Both of
which have same interface and operation. The modes will be described in
Chapter 2.
While the Power knob is turn on, it takes several seconds to initialize the
controller and other units. Make sure that the power’s output connection
terminals are correctly connected. Then, All the functions and parameters can
be set and run via touch panel displayer or GUI software.
