If the power has to be supplied from two power sources due to low capacity of the DC power
supply unit, etc., be sure to connect the minus lines of the two power supply units.

(AWG24) to ground equipment. Ground resistance must be
less than 100
Ω
(class D). Note that the ground cable must not be connected to the same
ground as the power circuits. Grounding is recommended but if a proper ground cannot be
provided the PC will still operate correctly without being grounded.
