WARNING

Correct grounding is very important. Failure to complete the grounding procedures may result in a system that is unsafe for the personnel using the equipment. If your system is not grounded correctly, it may not be protected from lighting or power surges, and it may be subject to service interruptions.

You must use insulated ground wire for system grounding.

Chassis powered by the same service panel

For each Main Chassis, connect a #6 AWG (#40 Metric Wire Gauge) ground wire from the Main Chassis to an NTBK80 grounding block. Connect the grounding block to a ground source (the ground bus in the AC service panel).
