2. SYSTEM CONFIGURATIONS
The NEAX2000 IVS system provides four installation methods as follows:
• Floor Standing Installation
• Wall-Mounting Installation
• 19-Inch Rack-Mounting Installation
• Desk Top Installation
This equipment can only be serviced by a qualified service person.  
Examples of system configurations for each installation method are shown in Figure 2-2 through 2-7.

CHAPTER 3 INSTALLATION PROCEDURE
1. PRECAUTIONS
1.1 GROUNDING REQUIREMENTS
The system grounding must have a specific ground resistance and AC noise level, and is to be connected to a
pre-determined terminal in the NEAX2000 IVS. Standard grounding requirements are as shown below:
• Communication grounding : Less than 10 ohm
• Protective ground for PIM: Less than 10 ohm
Note:The AC ripple on these various grounds should be less than 0.5 Vp-p.
The following specific requirements apply to ground wiring.
1.1.1 EQUIPMENT GROUND
An equipment grounding conductor that is at least as large as the ungrounded branch-supply conductors is to be
installed as part of the circuit that supplies the NEAX2000 IVS.  Bare, covered, or insulated grounding conduc-
tors are acceptable.  Individually covered or insulated equipment grounding conductors shall have a continuous
outer finish that is either green, or green with one or more yellow stripes.  The equipment grounding connector
is to be connected to ground at the service equipment.
The attachment-plug receptacles in the vicinity of the NEAX2000 IVS are all to be of a grounding type, and the
equipment grounding conductors serving these receptacles are to be connected to earth ground at the service
equipment.
1.1.2 SUPPLEMENTARY GROUND
In addition to the equipment grounding conductor in the power supply cord, a supplementary equipment ground-
ing conductor shall be installed between the product or system and ground.  This conductor shall be at least as
large as the ungrounded branch-supply conductors.  It shall be connected to the NEAX2000 IVS at the terminal
provided, and shall be connected to to ground in a manner that will retain the ground connection when the
NEAX2000 IVS is unplugged from the receptacle.  
The connection to ground of the supplementary equipment grounding conductor shall be in compliance with the
rules for terminating bonding jumpers in Part K of Article 250 of the National Electrical Code, ANSI/NFPA 70.
Termination of the supplementary equipment grounding conductor is permitted to be made to building steel, to
a metal electrical raceway system, or to any grounded item that is permanently and reliably connected to the
electrical service equipment ground.
Bare, covered, or insulated grounding conductors are acceptable.  A covered or insulated grounding conductor
shall have a continuous outer finish that is either green, or green with one or more yellow stripes.
CAUTION
Grounding circuit continuity is vital for safe operation of telecommunication equipment. Never operate this
equipment with the grounding conductor disconnected.
