†
The total output current should not exceed 1.5 A. For example, if 3.3 V at 0.25 A
is required, 1.25 A is available on the 5 V output.
Wiring
24 V DC is internally isolated from frame ground and the +5 V, +3.3 V outputs in
the Power Supply. Floating 24 V DC supplies can be used.

+
Connect an appropriate source of 24 V DC to the power supply.
Terminals accommodate one AWG #14 (avg. 2.1mm
2
cross
section) to AWG #22 (avg. 0.36mm
2
cross section) wire, or two
wires up to AWG #18 (avg. 0.86mm
2
cross section). Use copper
wire rated for 90°C. When inserting two wires in the same position,
the wires must be the same size and type (solid or stranded).
Connect the ground terminal to the conductive mounting panel
with a 10 cm (4 in) maximum length of AWG #14 (avg. 2.1mm
2
) or
larger wire. Use hardware such as star washers to ensure ground
integrity.
