2.2.2 Installing the UPS
I. Connect external battery of long backup time UPS
This step is saved for standard UPS.
1. Please match the UPS model with the battery voltage: 1kVA UPS
uses 36V battery
consisting of 3 12V cells in series
; among 2kVA UPS,
UH11-0020 UPS and UH11-0020L UPS use 120V battery
consisting
of 10 12V cells in series
, UH11-0020B UPS and UH11-0020LB UPS
use 96V battery
consisting of 8 12V cells in series
; 3kVA UPS uses
120V
battery
consisting of 10 12V cells in series
. To avoid abnormal
condition, see to it that the cell number is correct, no more, no less;
Notice
Battery cells by different manufacturer, of different model or use
state can not be combined to constitute a battery.
2. Use voltmeter to check and make sure the external battery socket
has no voltage output;
3. Make sure that the battery switch is placed to OFF;
4. As shown in Fig. 6(a) and Fig. 6(b), connect the battery cables to
the external battery socket. Make sure that the battery poles are not
reversely connected.: red indicates positive pole (+), and black
indicates negative pole
(
). The cables should have redundant
length to avoid inadvertent pulling off. If the external battery cables
delivered with the UPS are not long enough, lengthen them
according to actual need, yet, to maximally 8 meters. The sectional
area of the cables should increase with the length, if the cables are
relatively long, twist them;
