as to protect it against excessive humidity and or heat sources.
ώThe UPS cooling is depending on fan, so it should be kept in good air ventilation
area. There are many ventilation holes on the front and rear, so they should not be
blocked by any exotic obstacles.
ώExternal Battery
The UPS and its associated batteries are protected against the effect of over-current
through a DC compatible thermo-magnetic circuit-breaker (or a set of fuses) located
close to the battery.
ώUPS Output
Any external distribution board used for load distribution shall be fitted with protective
devices that may avoid the risk of UPS overloaded.
ώOver-current
Protection device shall be installed at the distribution panel of the incoming main
supply. It may identify the power cables current capacity as well as the overload
capacity of the system.
(Load coefficient equals max load in high altitude place divided by nominal power of the
UPS)
For safety reasons, it is necessary to install, external circuit breaker at the input A.C. supply
and the battery. This chapter provides guidelines for qualified installers that must have the
knowledge of local wiring practices for the equipment to be installed.
ώThe highest altitude that UPS may work normally with full load is 1500 meters. The
load capacity should be reduced when this UPS is installed in place whose altitude is
higher than 1500 meters, shown as the following table:

3.10 COMPUTER ACCESS
3.9.2 Parallel cable installation
3.9.3 Requirement for the parallel system
Shielded and double insulated control cables available must be interconnected in a ring
configuration between UPS units as shown below. The ring configuration ensures high
reliability of the control.
A group of paralleled UPS behaves as one large UPS system but with the advantage of
presenting higher reliability. In order to assure that all UPS are equally utilized and comply
with relevant wiring rules, please follow the requirements below:
1. All UPS must be of the same rating and be connected to the same bypass source.
2. The outputs of all the UPS must be connected to a common output bus.
3. The length and specification of power cables including the bypass input cables and the
UPS output cables should be the same. This facilitates load sharing when operating in
bypass mode.
ώOne end of a USB cable connect to the computer, the other end connect to the USB
port on the UPS.
ώOpen the software Muser4000, click “system” button.

ώNormal mode
The rectifier/charger derives power from the AC Mains and supplies DC power to the
inverter while floating and boosting charge the battery simultaneously. Then, the
inverter converts the DC power to AC and supplies to the load.
The UPS is a double-conversion on-line UPS that may operate in the following alternative
modes:

ώBattery mode (Stored Energy Mode)
If the AC mains input power fails, the inverter, which obtains power from the battery,
supplies the critical AC load. There is no power interruption to the critical load. The
UPS will automatically return to Normal Mode when AC recovers.
ώBypass mode
If the inverter is out of order, or if overload occurs, the static transfer switch will be
activated to transfer the load from the inverter supply to bypass supply without inter-
ruption to the critical load. If the inverter output is not synchronized with the bypass
AC source, the static switch will perform a transfer of the load from the inverter to the
bypass with power interruption to the critical AC load. This is to avoid paralleling of
unsynchronized AC sources. This interruption is programmable but typically set to be
less than an electrical cycle e.g. less than 15ms (50Hz) or less than 13.33ms (60Hz).

ώECO Mode
When the UPS is at AC Mode and the requirement to the load is not critical, the UPS
can be set at ECO mode in order to increase the efficiency of the power supplied. At
ECO mode, the UPS works at Line-interactive mode, so the UPS will transfer to bypass
supply. When the AC is out of set window, the UPS will transfer from bypass to Inver-
ter and supplies power from the battery, and then the LCD shows all related informati-
on on the screen.
ώMaintenance mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load
when the UPS is out of order or in repair and this manual bypass switch bears for
