Installing Power and Ground Wiring
2
Power Supply terminals accommodate one AWG #14 (avg. 2.1mm cross
2
section) to AWG #22 (avg. 0.36mm cross section) wire, or two wires up to
2
AWG #18 (avg. 0.86mm cross section). Use copper wire rated for 90 deg C.
When inserting two wires in the same position, the wires must be the same size
and the same type (solid or stranded).
Connect the ground terminal to the conductive mounting panel with a 4 in
2
maximum length of AWG #14 (avg. 2.1mm ) wire. Use hardware such as star
washers to ensure ground integrity.
Grounding DC Power Supplies
DC power supplies are non-isolated. DC- must be grounded to frame / earth
ground. DC- is grounded to frame internally in the Power Supply. As a result,
floating power supplies cannot be used.

Grounding AC Power Supplies
AC power supplies are isolated. Therefore, the AC source does not have to be
grounded. However, it is recommended to only use ground-referenced sources
such as a neutral line or grounded center-tap transformer.
