(9) No matter the UPS is connected to the utility power or not, the output of the UPS may have
electricity. The parts inside the unit may still have hazardous voltage after turning off the UPS.
To make the UPS have no output, power off the UPS, and then disconnect the utility power
supply.
(10) Suggest charging the batteries for 8 hours before use. After connection, turn the input
breaker in the “ON” position, the UPS will charge the batteries automatically. You can also use
the UPS immediately without charging the batteries first, but the backup time may be less than
the standard value.
(11) If it is necessary to connect the inductive load such as a motor or a laser printer to the UPS,
the start-up power should be used for calculating the capacity of the UPS, as its start-up power
consumption is too big when it is started.
2.4 Connect External Batteries(Long Backup Model UPS)
1.The nominal DC voltage of external battery pack is 192 Vdc. Each battery pack consists of 16
pieces of 12V maintenance free batteries in series. To achieve longer backup time, it is
possible to connect multi-battery packs, but the principle of “same voltage, same type” should
be strictly followed.
2.For UPS 6/10KH, select the UL1015 10/8AWG(6/10mm
2
)or other insulated wire which
complies with UL Standard for the UPS battery wirings. The procedure of installing battery bank
should be complied with strictly. Otherwise you may encounter the hazardous of electric shock.
(1) A DC breaker must be connected between the battery pack and the UPS. The capacity of
breaker must be not less than the data specified in the general specification.
(2) Set the battery pack breaker in “
OFF
” position and connect the 16 pieces of batteries in
series.
(3) You must connect the external battery cable to the battery first, if you connect the cable to
the UPS first, you may encounter the hazardous of electric shock. The positive pole of the
battery is connected to the UPS with red wire; the negative pole of the battery is connected to
the UPS with black wire; the green and yellow ribbon wire is connected to the ground of the
battery cabinet.
3. To complete the connection of the external battery cable into the UPS. Do not attempt to
connect any loads to the UPS now. You should connect the input power wire to the right
position first. And then set breaker of the battery pack in the “
ON
” position. After that set the
input breaker in the“
ON
” position, the UPS begins to charge the battery packs at the time.
