Grounding the Chassis
The 3916 is connected to ground at the power supply and the chassis.
Note: The Battery Return lead is considered DC-I (isolated from frame
ground) as described in GR-1089-Core, Issue 6.
Power Supply Grounding
The safety ground connection is provided by the AC power cord or by the
ground terminal on the DC power input connector.
Supplemental Ground
On standard chassis systems a supplemental ground connection is provided
for connection to a Common Bonding Network (CBN). The supplemental
ground connection is required on 3916 DC Standard installations. The
supplemental ground connection is optional on 3916 AC Standard and 3916
Dual AC Standard installations. Mini chassis systems do not require a
supplemental ground connection.
The grounding screws are located on the left side of the standard chassis. See
Figure 2-1. The ground location will support a 2-hole lug.

WARNING
The AC version relies on the AC power cord for Safety Ground.
The outlet providing power to the 3916 must meet the Local
and National Safety codes.
WARNING
The DC version relies on the connector at the front of the
power supply to provide Safety Ground. This grounding
connection must be properly attached when the 3916 is
installed.
