PowerWAVE 9000 DPA UPS - Multi-Cabinet Configuration
(Issue 2.1 Oct. 2009)
WHEN CABLING THE UPS CABINETS, ENSURE THAT EACH UPS IS
COMPLETELY VOLTAGE FREE. CHECK THAT THE MAINTENANCE
BYPASSES (IA1) AND ALL PARALLEL ISOLATORS (IA2) ARE OPEN
(“OFF”) ON ALL CABINETS.
6.2.2 Connection of Parallel Communication Cables (Bus-lines)
For the correct performance of different parallel UPS functions and
operations, the paralleled units communicate continuously between each
other. This is achieved by means of the 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 sequential between the
units. Communication BUS lines are connected as shown below
(See
Figure 6.3)
.
NOTE:
Only connect the Bus Line cables when the UPS cabinets are
switched off and each parallel isolator IA2 is open.
Follow Bus Line cable connection sequences detailed below.
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;
3.
Connect PORT JD6 on Parallel Adapter of UPS-Cabinet 1and PORT
JD5 of Parallel Adapter of UPSCabinet 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..
