Making Ground Connections

Use the procedure in this section for both the main shelf and the Expansion panel.
After installing the TimeProvider shelf and/or the Expansion panel into the rack,
make the grounding connections as follows.
Recommendation: Although there are a number of methods for
connecting the equipment to earth ground, Symmetricom
recommends running a cable of the shortest possible length from
the ground lug to earth ground.
Front Access Shelf
To connect Chassis Ground on the front access chassis, connect a cable from the
frame ground lug on the left side of the front panel to the proper grounding zone or
master ground bar.
Rear Access Shelf
To connect Chassis Ground on the rear access shelf, connect a cable from Pin 3 of
the power connector to the proper grounding zone or master ground bar.
Expansion Panel
All connections to the Expansion Panel, including chassis ground, are made using
the interconnection cable.

Making Power Connections

The TimeProvider front- and rear-access shelves use different types of power
connectors. Each shelf is delivered with the appropriate connector and shell.
Electrical Shock Caution: To avoid possible injury from shock,
make sure that the fuses are removed from the fuse panel or
power supply before connecting or applying power to the unit.
Warning: For continued fire protection, replace power supply
fuse(s) with the specified type and a 5 A rating. There are no
user-serviceable fuses in the TimeProvider shelf.
This unit must be grounded.
Refer all servicing to qualified personnel.
