Making Ground Connections
After the TSG-3800 is installed in a rack, the shelf must be connected to a proper
earth ground.
1. Run a cable from the frame ground (FG) lug to earth ground.
Keep this cable as short as possible. Frame ground connections are made using
the #8-32 stud labeled
FG
on the lower left corner of the rear panel.
2. Using a digital voltmeter, measure between ground and chassis and verify that
no voltage potential exists between them.
Making Alarm Connections
To make alarm connections to the TSG-3800:
1. Locate the ALARM terminal block connectors labeled MAJOR ALARMS (TB1)
and MINOR ALARMS (TB2) on the rear panel, see
Figure 2-2
,
Figure 2-3
, and
Figure 2-4
.
Both terminals contain REMOTE, LOCAL, and AUDIO alarm connections. Three
contacts are provided for each alarm: normally closed (NC), normally open (NO),
and common (COM). Refer to
Figure 2-5
for terminal screw assignments.
