Power Requirements for Sourcefire Devices
3D7010/7020/7030
Appendix A
Frequency Range
The frequency range of the AC power supply is 47 Hz to 63 Hz. Frequencies
outside this range may cause the appliance to not operate or to operate
incorrectly.
Power Cord
The power connection on the power supply is an IEC C14 connector and accepts
IEC C13 connectors. A UL-recognized power cord must be used. The minimum
wire gauge is 16 AWG. The cord supplied with the appliance is a 16 AWG,
UL-recognized cord with NEMA 515P plug. Contact the factory about other power
cords.
IMPORTANT! Do not cut the cord on the power supply.
Grounding/Earthing Requirements
The appliance must be grounded to the common bonding network.
Bonding Location
A ground bonding location is provided on the rear of the chassis. An M4 stud is
provided. An outside-toothed lock washer is provided for attaching a ring terminal.
A standard ground symbol is available by each stud.
The following illustration indicates the bonding location on the chassis.
Recommended Terminals
You must use a UL-Approved terminal for the ground connection. A ring terminal
with a clearance hole for #6 (M3.5) stud may be used. For 16 AWG wire,
AMP/Tyco 36151 is recommended. This is a UL-approved ring terminal with a hole
for a #6 stud.
Ground Wire Requirements
The ground wire must be sized sufficiently to handle the current of the circuit in
case of a single fault. The size of the ground wire should be equal to the current
of the breaker used to protect the circuit. See
Current on page 241.
Bare conductors must be coated with antioxidant before crimp connections are
made. Only copper cables can be used for grounding purposes.
