ٟ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 sourcesᇭ
CAUTION!
An unused battery must be recharged every 6months. 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
ٟTo get the UPS completely monitored by the software, you just simply connect RS232
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 below.
