Operation Sorensen SFA Series
an OCP externally, apply a 10.5–13.3 VDC signal to J1-3 for a minimum of four
(4) seconds.
3.7
REMOTE SHUTDOWN (S/D)
A 12 VDC voltage can be connected externally between terminals J1-
18 (S/D Fault) and J1-24 (COM) to disable, i.e., shut down the output of the
power supply. Disabling or opening the +12 VDC signal will allow the unit to
revert to normal operation.

MASTER/SLAVE OPERATION
The following modes of operation are used for applications requiring more
current or voltage than is available from a single power supply. To meet the
requirements for greater output voltage or current, two supplies may be
connected in series or up to five connected in parallel.
3.8.1
P
ARALLEL
O
PERATION
In the parallel mode of operation, a master/slave configuration is established.
Up to five power supplies may be paralleled using this configuration. To set up
the parallel mode of operation, connect the interface cable (Elgar P/N 890-453-
03) from the master unit to the slave unit(s), as shown below in Figure 3–13.
Next connect the positive outputs of supplies together and the negative outputs
of the supplies together. It is recommended that the outputs are connected
together as close to the load as practical.
