WARNING!
Typical battery performance data are quoted for an operating temperature of
20°C.. Operating it above this range will reduce the battery life while
operation below this range will reduce the battery capacity.
Should the equipment not be installed immediately it must be stored in a room so as to
protect it against excessive humidity and or heat sources.
CAUTION!
An unused battery must be recharged every 3months. Temporarily
connecting the UPS to a suitable AC supply and activating it for the time
required for recharging the batteries are required.
The 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:
（Load coefficient equals max load in high altitude place divided by nominal power of the UPS）
Altitude（m）
1500 2000 2500 3000 3500 4000 4500 5000
Load coefficient 100% 95% 90% 85% 80% 75% 70% 65%
To monitor the UPS via software, simply connect an RS232 or USB cable to each end of
the computer and the UPS respectively.
3.5 External Protective Devices
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.
◆External 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.
◆UPS Output
Any external distribution board used for load distribution shall be fitted with protective devices that
may avoid the risk of UPS overloaded.
◆Over-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 .
CAUTION !
Select a thermo magnetic circuit-breaker with an IEC 60947-2 trip curve C
(normal) for 125% of the current as listed on the next page.
