outage is known to last for more than few minutes, it is advisable to turn off the system
instead of using the battery up while repeatedly using it up reduces the battery life
dramatically.
The battery will undergo self-discharging over time even when not in use (not
connected). A useful advice to preserve the battery at best condition is to regularly
recharge the battery if the battery is put in storage for a period of time. It is
recommended to turn on the system to recharge the battery for 1 ~ 2 hours every 3
months of storage if the storage temperature is lower than 30
°
C. The battery should be
recharged for 1 ~ 2 hours every month if the storage temperature exceeds 30
°
C.
However, the user shall avoid the situation with storage temperature over 30
°
C to
protect the life of the battery. Do not connect any other battery to this UPS battery
because mixed use of batteries of different capacity, history, or manufacturers may
cause damages. In case the user wants to have a longer battery support time during AC
power off, he/she should consult his/her dealer for application of an external 12 V
battery.
When the UPS battery is installed in the KS system with power off, the standby
current will consume the battery much faster than self-discharge. An over-discharged
battery will not only mean premature death of the battery itself, it also may cause
danger when later being recharged. It is therefore absolutely important that the end
user shall
disconnect the UPS battery from the system when the system is to be
powered off for more than 72 hours and replace a new battery whenever the
monitoring software indicates the battery is out of service
.
UPS STATUS DETECT FUNCTIONS
The UPS function requires use of the optional UPS battery. The Posiflex UPS
functions can support the system against intermittent power failure. However, in order
to achieve best hardware stability against any possible memory or CMOS data loss or
even system crash, the UPS function will be automatically enabled or disabled
depending on the existence of a healthy UPS battery.
In the Jiva KS series products, when the system is working on UPS battery
power, the status is indicated by LED and is detectable by software. This “operating on
battery” signal can be obtained through checking the communication status of COM1
at signal DCD provided this signal is not engaged elsewhere (In other words, Modem
