2. 3 Operating Principle
Figure 2-3 The UPS operating principle
1. Input filter: it filters the input and provides clean AC power to the UPS.
2. AC/DC converter: In Normal mode, it converts the AC input power to
regulated DC power, and raises the regulated DC voltage for DC/AC
converter.
3. DC/DC converter: Raises the DC Voltage from the battery system to the
optimum operating voltage for the inverter when the UPS operates in Battery
mode.
4. DC/AC inverter: In Normal mode, it utilizes the DC output of the AC/DC
converter and inverts it into precise, regulated sine wave AC power. In
Battery mode, it receives energy from the battery through the DC/DC
converter.
5. Bypass: It is very important in the UPS system. In the event of a UPS fault
that will not lead to UPS shutdown, the load will be automatically
transferred to the bypass. Meanwhile, the LED indicators will indicate the
7
2 Product Description
fault type, and the fault information will be reported through the
communication ports.
6. Charger: The charger of standard UPS provides 1A charging current; and
long backup time provided 1K is 6.5A and 2K/3K is 5.5A charging current.
7. Battery: Sealed maintenance-free lead –acid battery can be used as the DC
source of the UPS.
8. Output filter: It filters the output and provides clean AC power to the load.

3. 1 Unpacking Inspection
1. Open the packing box of UPS and take it out, visually examine the unit for
transit damage.
2. Check against the accessory lists that the accessories of the UPS are present.
(Refer to Table 9-1).
3. Make sure the model is what you wanted from the nameplate on the rear
panel
4. If the UPS arrives damaged, or there is any missing accessory or other
question above, please contact the distributor immediately.
3. 2 Installation Notes
1. When locating the UPS, make sure there is no hazardous objects such as
water, inflammable gas, corrosive agents and so on around the UPS, and that
the installation environment meets the specifications.
2. The UPS should not be placed on a side. The air inlet port at the front panel
and the outlet port on the rear panel and two side panels should not be
blocked so as to ensure good ventilation.
3. In case if the UPS is unpacked, installed and used at very low temperatures,
condensations of water drops may appear. It is necessary to wait until the
UPS fully dried inside out before proceeding to installation and use.
Otherwise, they may be a risk of electric shock.
4. Place the UPS near the utility power source outlet which supplies power to
the UPS. In any emergency, switch off the main input socket, cut off the
battery voltage input. All power sockets must be connected with ground
protection.

3.3 Cable Connection
3.3.1 Connecting Input and Output Cables
1. Input cable connection
If the UPS is connected via the power cable, please use a proper socket with
over current protection, and pay attention to the capacity of the socket: over
10A for 1K(S/L), over 16A for 2K(S/L) and 3K(S/L). A side of input wiring
has been fixed with the UPS, and the other side is just need to plug into the
input socket. The wiring configuration is shown in the following diagram.
Figure 3-1 Connection Method of Input
2. Output cable connection
The output of 1K(S/L)/ 2K(S/L)/ 3K(S/L) all available to uses sockets. The
total output power shall not exceed 1kVA/0.8kW, 2kVA/1.6 kW，3kVA/2.4
kW. Simply plug the load power cable to the output sockets of UPS to
complete connection as shown in the following diagram.

3.3.2 Operation Procedure of External Battery for Long Backup Time
UPS
The battery connection procedure is very important for long backup model.
Any incompliance may result in the risk of electric shock. Therefore, the
following steps must be strictly complied with.
1. First connect in series the batteries of the pack to ensure proper battery
voltage that 1KS/1KL for 36VDC, 2KS/2KL for 72VDC (or 96VDC),
3KS/3KL for 96VDC (or 72VDC).
2. Take out the battery cable delivered with the UPS, one end of the external
battery cable is a plug for connecting the UPS, the other end has 3 open
wires for connecting the battery pack.
3. Connect the external battery cable to the battery terminal (DO NOT connect
the battery socket of the UPS first. Otherwise, it may cause electric shock).
Connect the red wire to the “+” terminal of the battery. The black wire is
connected to the “-” terminal of the battery. The green/yellow wire is
grounded for protection purpose.
4. Connect the plug of the external battery cable to the external battery slot on
the rear panel of the UPS to complete the connection procedure.
