Chapter 2 Installing
Making Ground and Power Connections
After installing the TimeProvider 5000 into the rack, connect the chassis to the
proper grounding zone or master ground bar. Run a 16 AWG green/yellow-striped
insulated wire from the TimeProvider 5000 grounding terminal to the Earth Ground
on the rack. The rack grounding method is below.
1. Crimp the customer-supplied UL listed Ring Lug to one end of the 16 AWG wire
and connect it to the ground terminal on the left side of the front panel using the
supplied M4 Kept machine nut. The surface of the TimeProvider 5000 Earth
grounding terminal must be clean of contaminants and oxidation.
2. Crimp the appropriate customer-supplied UL listed Ring Lug to the other end of
the 1 mm² / 16 AWG green/yellow-striped wire. Remove the paint and sand the
area around the screw hole to ensure the proper conductivity. Coat the
connection with an electrically conductive antioxidant compound such as
Kopr-shield spray. Connect this Ring Lug to the rack with appropriate customer
supplied screws and external star lock washers.
3. Using a digital voltmeter, measure between the ground and chassis and verify
that no voltage exists between them.
Power Connections
Use the following procedure to make the power connections:
1. Ensure the power source is turned off.
2. Connect the frame ground terminal to earth ground.
3. Locate the power connectors included in the installation kit, Phoenix Contact p/n
MC 1,5/2-STF-3,81.
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.
Warning: To avoid possible damage to equipment, you must provide
power source protective fusing as part of the installation. The
TimeProvider 5000, TimeProvider E10 and TimeProvider E30 are
intended for installation in a restricted-access location.
Caution: To avoid damage to the unit, remove the fuses in the fuse
panel which provides power to the TimeProvider 5000, TimeProvider
E10 and TimeProvider E30 before making power connections.
