Installation and User Manual
1.4 Prerequisites to Installation
An efficient installation depends on careful planning and site preparation. Installation of the equipment must be han-
dled by skilled technicians and electricians familiar with the special requirements of high-voltage electrical equip-
ment. The installation must comply with the requirements of the National Electrical Code (ANSI/NFPA 70, latest
issue) and local codes as applicable, and safety standard, UL1012 listed; ul1449 compliant; meets FCC Cat. A.
1.5 General Description
The overall function of the Topaz 100 Ultra-Isolator is to attenuate transients and noise that originate on the
incoming power lines and provide a newly derived, isolated power source.
The Topaz 100 Ultra-Isolators are used to protect sensitive electronic equipment and computers from power line
noise and transients. There are common disturbances on the power lines caused by lightning, motor starting and
stopping, utility network switching and general electrical noise, which will adversely affect sensitive electronic
equipment, especially computers.
The Topaz 100 Ultra-Isolator utilizes a unique method of shielding and isolation which provides low capacitive
coupling between input and output circuits. This low capacitance, together with a highly effective filter circuit, results
in ultra high common mode and normal mode noise attenuation.
