CHECKING THE GROUND CONNECTION
Use an ohmmeter to check the electrical resistance between the console’s metal case and the earthing ground
wire’s connection at the “known good earth ground”. It should read less than 1 ohm.

POWER WIRING NOTES:
1. Barrier ground must be #12 AWG or larger.
2. Check to be sure that the electrical resistance between the console ground
lug and a known good earth ground is less than 1 ohm.
3. Connect the power supply wires in the power panel to a separate dedicated circuit.
4. Electrical rating power input -- 120 Vac or 240 Vac, 50/60 Hz, 100 W maximum.
5. See the "Console Dimensions and Designated Conduit Knockouts" diagram for
actual locations of power conduit knockouts into the console. Power wiring conduits
must enter Power Bay knockouts.
