The safety ground connection is provided by one of the following:
• DC power supply — by the grounding terminal on the DC power supply
• AC power supply — by the AC power cord
Supplemental Ground
A supplemental ground connection is provided for connection to a Common
Bonding Network (CBN). The grounding screws are supplied and are located
to the right of center on the rear of the chassis. See Figure 2-2 on page 2-18.
You are required to provide the grounding lug and grounding wire. The
following description indicates the required specifications:

when the 5150 is installed.
WARNING: The AC version relies on the AC power cord for Safety Ground. The
outlet providing power to the 5150 must meet the Local and National Safety codes.
