When connecting 2 or 3 units in parallel, the combined power may be drawn
from a single connector. A single connector can handle 30 A.
DC output or optional input for daisy-chaining
The second DC connector (DC 2) of the AC/DC Power Supply can be used for 2
purposes, to provide DC output or to serve as an input connector when daisy-
chaining up to 3 AC/DC Power Supply units.
To connect to DC2 do as follows:
1. To have a second DC output:
Connect the DC cable to the connector marked DC1 and the equipment that
must be powered.
2. To daisy-chain a second AC/DC Power Supply.
Connect the cable from DC1 in AC/DC Power Supply unit 1 to DC2 in AC/DC
Power Supply unit 2.
Connect the DC cable to the connector marked DC 2 and the equipment
that must be powered.
3. Remove the u-shaped cut-out for this input from the protective lid.
To daisy-chain a third AC/DC Power Supply repeat step 2. The connector
specifications are the same as for
DC1 .
