Supplying Power to the Unit
As shipped, NetVanta 5305 is set to factory default conditions. After installing the chassis and any option
modules, the system is ready for power up. To power the system, ensure that the unit is properly connected to
an appropriate power source (as outlined in the sections which follow).
NetVanta 5305 (AC)
The AC-powered NetVanta 5305 comes equipped with a detachable 6-foot power cord with a 3-prong plug
for connecting to a grounded power receptacle. To power up the unit, ensure that the power cord is securely
attached to the unit (located on the rear panel) and connect the cord to the appropriate power supply.
AC Grounding Instructions
The following paragraphs provide grounding instructions for the NetVanta 5305:
Redundant AC Power Supplies (Optional)
A redundant AC power supply can be installed as a backup power supply for the system. Two redundant AC
power supplies are available and can be purchased separately: a 120 VAC supply (P/N 1200840G1#120) and
a 240 VAC supply (P/N 1200840G1#240).
• Power to the NetVanta 5305 AC system must be from a grounded 85 to 250 VAC,
4 A/2 A, 50/60 Hz source.
• In addition to the equipment earthing conductor in the power supply cord, a
supplementary equipment earthing conductor is to be installed between the system and
earth.
• The supplemental earthing conductor shall be connected to the equipment using a
number 8 ring terminal and should be fastened to the grounding lug provided on the
rear panel of the equipment. The ring terminal should be installed using the
appropriate crimping tool (AMP P/N 59250 T-EAD Crimping Tool or equivalent).
• The supplementary equipment earthing conductor must not be smaller in size than
cross-sectional area of not less than 2.5 mm
2
, if mechanically protected. The
supplementary equipment earthing conductor is to be connected to the product at the
terminal provided, and connected to earth in a manner that will retain the earth
connection when the power supply cord is unplugged. The connection to earth of the
supplementary earthing conductor must be in compliance with the appropriate rules for
terminating bonding jumpers in Part K of Article 250 of the National Electrical Code,
ANSI/NFPA 70, and Article 10 of Part 1 of the Canadian Electrical Code, Part 1,
C22.1. Termination of the supplementary earthing conductor is permitted to be made
to building steel, to a metal electrical raceway system, or to any earthed item that is
permanently and reliably connected to the electrical service equipment earthed.
• Bare, covered, or insulated earthing conductors are acceptable. A covered or insulated
conductor must have a continuous outer finish that is either green, or green with one or
more yellow stripes.
• A readily accessible disconnect device, that is suitably approved and rated, shall be
incorporated in the field wiring.
• Maximum recommended ambient operating temperature is 50
°
