Installation Instructions
WARNING!
NOTE:
IN ORDER TO ACHIEVE EQUAL LOAD SHARING BETWEEN THE UPS-CABINETS, THE INPUT CABLE
LENGTHS FROM THE INPUT DISTRIBUTION BOARD TO THE UPS AND FROM THE OUTPUT CABLE TO THE
OUTPUT DISTRIBUTION BOARD SHOULD BE THE SAME RESPECTIVELY.
WHEN CABLING THE UPS'S BEWARE TO CONNECT INPUT AND OUTPUT WIRES TO THE CORRESPONDING
TERMINALS,
RESPECTING
EXAMPLE: PHASE1 OF UPS1 = PHASE1 OF UPS2 = ...... = PHASE1 OF UPS n
6.2.2
Paralleling of UPS-Cabinets
For the correct performance of different parallel functions and operations the parallel units communicate
continuously between each other. This is achieved by means of the so-called communication BUS-Lines.
After terminating the input and output cabling of each single UPS, it is necessary to connect the units together
to form the parallel system. For this purpose a communication BUS line is connected sequentially between the
units. Connect communication BUS lines according to Figure 14.
!
NOTE!
1.
Fit the Parallel Adapter over the Connector JD8 on all UPS-cabinets
2.
Set DIP Switch SW2-2 on each Parallel Adapter depending on the UPS Cabinet in the parallel cabinet
configuration (see Figure 15)
3.
Connect PORT JD6 on Parallel Adapter of UPS-Cabinet 1and PORT JD5 of Parallel Adapter of UPS-
Cabinet 2 with the corresponding BUS-Cable;
4.
Connect PORT JD6 on Parallel Adapter of UPS-Cabinet 2 and PORT JD5 of UPS-Cabinet 3 with the
corresponding BUS-Cable
5.
Continue in the same manner for the remaining UPS-Cabinets.
