The batteries must be charged min. 12 hours before first-use.
4.2.4. Output Connection
Please add double-pole miniature circuit breaker (equivalent to UPS output breaker) to distribution
board where the loads are to be connected. Connect the phase cable to output “L” terminal and
the neutral cable to output “N” terminal.
4.2.5. Communiation Interface Connection
Connectivity cards allow the UPS to communicate in a variety of networking environments and with
different type of devices.
The Communication port on the UPS provides true RS232 type to communicate with UPS software
to remote monitoring the power and UPS status.
With optional interfaces cards, which contains, RSE(RS485 plus EPO), USE(USB plus EPO), DCE(Dry
Contact plus EPO), as well as SNMP/ card, you may combine them according to your demand.
However, RSE card and USE card are prohibited to be used simultaneously.
The bundled software of the UPS is compatible with many operating systems such as Windows 98,
& 2000, ME, NT and XP.
In the event of an extended period of UPS non-operation, the batteries must be charged
periodically in order to prolong battery life. The charge period, which depends on the
temperature, is given in the
Section 3.3
of the manual.
To enable the short circuit protection feature of the UPS, each load shall be supplied through
a separate circuit breaker chosen according to the load current. This may provide quick
disconnection of the short circuited load and maintain operation continuity of the other
loads. To obtain maximum protection, the rating of each individual load circuit breaker shall
have the minimum value, which is enough to carry the full load current continuously.
Make sure that all circuit breakers are at “0” position before starting with the installation.
Each load should be supplied through separate circuit breaker and the cable cross section
should be chosen according to the load current value.
Make sure that the UPS is not overloaded to provide a higher quality supply to the loads.
