3.5 EXTERNAL PROTECTIVE DEVICES
ώ
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.
ώ
The 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.
ώ
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.
ώ
UPS Output
Any external distribution board used for load distribution shall be fitted with protective
devices that may avoid the risk of UPS overloaded.
ώ
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.
(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.
ώ
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:
WARNING! :
Typical battery performance data are quoted for an
operating temperature between 20°C and 25°C. Operating
it above this range will reduce the battery life while
operation below this range will reduce the battery
capacity.
CAUTION! :
An unused battery must be recharged every 6months
Temporarily connecting the UPS to a suitable AC
mains supply and activating it for the time required for
recharging the batteries.
