2-18 KLN Series 051614
2.8.2 PARALLEL CONNECTIONS
Up to five identical KLN units (one master and up to four slaves) can be operated in parallel to
increase the output current. Output current of the parallel combination = number of units in par-
allel x output current of a single unit.
CAUTION: OBSERVE CORRECT POLARITY FOR ALL CONNECTIONS.
See Figure 2-21A for parallel connections with local sensing and Figure 2-21B for parallel con-
nections with remote sensing. See PAR. 2.5.5 for guideline regarding load connections. See
PAR. 3.4.3 for instructions on operating units connected in parallel.
Connections for parallel operation can be simplified by using the optional Parallel Connector
Board (see Table 1-4) illustrated in Figures 2-21 and 2-22. When connecting two units in paral-
lel, connections can be further simplified by using the optional Parallel Connection Cable, Kepco
P/N 518-0121 which replaces the optional Parallel Connector Board and two Programming Port
cables shown in Figure 2-21. If neither the optional Parallel Connector Board nor the Parallel
Connection Cable are used, refer to Figure 2-23 for programming port connections required for
parallel operation.
