Grounding
• Ensure that you run continuous grounds from the
utility ground to the MicroVission. See Figure 1-3:
Ground Wiring.
• Grounds must be copper or aluminum wire.
• Never use conduit grounds.
Mixing Voltages
• Separate different voltages from each other and
separate AC from DC, see Figure 1-4: Mixed Voltage
Wiring.
• Each voltage level must be run in separate conduit:
• 460 VAC
• 230 VAC
• 120 VAC
• 24 VAC
• DC Signals
• If your installation site has wireways or conduit trays,
you must install dividers between the different
voltages.
