| Graphic User Interface (GUI) |
| A computer system using graphics images on the
screen rather than text to display application information for
the user. As used in the Power Management Software. |
| Ground( GND) |
| A conductor connected between a circuit and the
soil. As Esteem test it . |
| Hardwired |
| Describes any equipment connected to its power
source by hardware attached directly to terminal blocks or distribution
panels. |
| Harmonic Distortion |
| The presence of harmonics that change the AC voltage
waveform from a simple sinusoidal to complex waveform. Harmonic
distortion can be generated by a load and fed back to the AC
utility line, causing power problems to other equipment on the
same circuit. |
| Heterogeneous Network |
| A network with a multitude of workstations, and
operating systems, and a variety of application types from different
vendors. |
| High Rupturing Capacity (HRC) (fuse) |
| A precisely rated fuse which will operate under
high fault current conditions, without self destructing. |
| Homogeneous Network |
A network of components- workstation, server,
operating system from the same vendor, or compatible equipment
that can run under the same network or operating system

|
| Host Port |
| The serial port used for connecting the SM50 to
a remote computer via an RS-485 or an RS-232C connection. |
| Host Serial Port |
| One of the two serial ports (RS-232C or RS-485)
with connectors at the rear of the SM50. |
| Hot-Swappable Power Modules |
| A feature which enables the user to change UPS
power modules without powering down the connected load. |
|
| I/O |
| Input/Output |
| I/O Board |
| A component board in an SM50 Monitor. The board
is used to gather system digital and analogue inputs, and control
digital outputs. |
| ICE |
| Intergy Configuration Editor software running
under Windows 95 or Windows NT which allows editing of the SM50
configuration. |
| ILS |
| Intergy Large Power System |
| IMPS |
| Intergy Mini Power System |
| Input Line Cord |
| The covered bundle of wiring connected to the
input terminals of the UPS. The end of the cord not connected
to the UPS is connected, via an input plug, to an AC utility
outlet supplying power to the UPS. |
| Input Plug |
| Connected to the end of the input line cord. To
be plugged into an AC utility outlet receptacle |
| Internal Bypass |
| UPS circuitry which provides a redundant power
path. If there is an internal UPS fault, the connected load
will still be supplied with unconditioned utility power. |
| Inverter |
| A machine, device or system that changes direct
current power into alternating current power. |
| IPS |
| Intergy Medium Power System |
| Isolation |
| The separate (often through the use of an isolation
transformer) of one section of a system from undesired electrical
influences of other sections. |
| Isolation Transformer |
| A multiple-winding transformer with physically
separate primary and secondary windings. Although the two windings
are physically disconnected, the magnetic field in the windings
of the primary creates (induces) electrical power in the secondary
winding. In the way the electrical power available at the input
can be transferred to the output. An isolation transformer does
not transfer unwanted noise and transients from the input circuit
to the output windings. This attenuation, or reduction in amplitude,
could be as high as one million to one. |
