The surge suppressor should only be used
with a three-prong standard AC outlet. The
surge suppressor cannot provide complete
protection without a grounded AC source.
THE NEED FOR SURGE PROTECTION
The H293 is shown in an H290 8-outlet box
used in an Open House structured wire grid
system and in a power strip.
The surge
suppressor can plug into any of the outlets,
and will protect all the other units plugged
into an H290, H291, the power strip, or a J-
Box.
FOR INDOOR USE ONLY
DO NOT
:
use in damp areas or near water.
WARNING:
This surge suppressor is NOT a
lightning arrestor and may not protect against
lightning induced voltage surges.

The H293 bi-level Surge Suppressor
features a unique
(patent pending) two-stage, 960 joule surge protection circuit.
The first stage provides 640 joules of protection across the
hot-to-neutral connection with a response of only one
nanosecond before the clamping starts. With ordinary
single-stage surge protectors, a surge higher than the rated
number of joules, will disable the surge protector leaving the
devices near it unprotected. With our surge suppressor, this
event will disable only the first stage protection circuit, leaving
its devices protected by the second stage. The second stage
protection is still 340 joules across the hot-to-neutral
connection, making it more than many single state surge
protectors.
The H293 protection circuit clamps at 400 volts (UL 1449
rating) and provides protection from surges up to 6,000 volts
without being damaged. It also provides protection up to 72,000
amps (48,000 hot to neutral, 12,000 hot to ground and 12,000
neutral to ground) without being damaged. A noise filter helps
audio and video devices maintain steady performance by
recuding static and RFI on the AC line.
There are built in status lights that indicate exactly how much
protection is currently available (see Status Lights below).
When a large surge or spike occurs beyond the specified limits,
the suppressor should protect the attached equipment, but the
primary protection circuit will now be inactive. Even so, in this
believe design, there is still partial protection for the equipment
that will work against a second large surge. It is advisable that
when the lights indicate partial protection (Green - Flashing),
the unit should be replaced soon.
The AC electrical lines can experience sudden surges in
voltage (up to 6000 volts) from sources outside and inside
the home. Outside sources could include industrial
equipment being used nearby, while inside sources could
be air conditioning units turning on and off, refrigerators
and other major appliances. These can damage electronic
components, cause loss of data, input/output errors, and
computer system crashes. When spikes and surges occur
in your home, the surge suppressor will protect your
equipment by reducing these voltages to a safe level.
