3.7. UPS Initial Start-up
NOTE: Before starting up, verify that the total equipment ratings do not exceed the UPS capacity in order to prevent
an overload alarm.
To start-up the UPS:
①If optional EBPs are installed, verify that the EBPs are connected to the UPS.
②Connect the equipment to the load to be protected, but do not turn on the protected equipment.
③It is necessary to make provisions for cord fastening and strain relief.
④Plug the detachable UPS power cord into the input connector on the UPS rear cover.
⑤Plug the UPS power cord into a power outlet. The display on front side illuminates.
⑥The UPS performs a self-test when starting. After that, the charger will charge the battery. If the output
displayed on LCD is «0», then there is no output. If you need output current without starting the UPS during
connection to the mains, then you need to set bPS option to «ON» in setting mode (refer to page 19 «Bypass
Mode Setting».
⑦Press the combination of start-up buttons on UPS front cover for at least ½ second. The UPS will start up
and the LED will turn on and off sequentially.
⑧Check the UPS front cover for active alarms or messages. Rectify any active alarms before continuing. Refer
for that on table 23 «Troubleshooting» on page 36. If the indicator is on, do not proceed until you have
removed all alarms. Check the UPS status on front cover to view the active alarms. Correct the alarms and
restart if necessary.
⑨Verify that the indicator is illuminated. It indicates that the UPS is operating normally and that any loads
are powered.
⑩If optional EBPs are installed, then refer to page 24 «Battery number configuration» to adjust the installed
number of EBPs.
⑪To change any other standard default factory settings, see on page 19 «Parameter Settings».
⑫If you installed an optional EPO, then test the EPO function: activate the external EPO switch. Verify the
status change on the UPS display. Deactivate the external EPO switch and restart the UPS.
a) NOTE: At initial start-up, the UPS sets the system frequency according to input frequency of the line (the input
frequency auto-sensing is enabled by default).
b) NOTE: At initial start-up, please set the needed output voltage before you are starting up the UPS. After the
subsequent start-up, the UPS will output the setting voltage.
c) NOTE: The internal batteries charge up to 80% of capacity in less than 5 hours. However, we recommend after
installation or long-term storage that the batteries are charged during 48 hours. If optional EBPs are installed, refer
to recharge times listed in table 21 «Battery runtimes at 100% load» on page 34.
