Installing and Grounding Power Supplies
This section describes the installation and grounding of Multi-line,
Quint-line, and Dual-line shelves and power supplies.
Shelf Grounding To ground the shelves, connect separate chassis and signal ground
connections from TB1 on the first shelf (Multi-line or Dual-line
shelf), to the local building or rack ground locations. Refer to
Figure 4-3 .
1. Connect TB1 pin 4 (signal ground) on each shelf to the
building ground.
2. Tighten the connecting screws to secure the wires in place.
3. Extend the building ground path to any additional shelves.
NOTE: For multi-line shelves, ground each shelf unit to the chassis
building ground.
