Important Notice
To avoid shock or damage, do not plug in or turn the system on before completing the
installation process. <No Power-ON Maintenance>
Avoid working with the KSU during electrical storms.
Use only commercial AC Power to prevent shock or fire.
Use the power cord supplied for the KSU.
Do NOT bundle AC Power cords together, the cords may over heat.
Make sure the KSU has proper Earth Ground.
The system should be “Wall-Mounting” only.
A dedicated 110/240VAC circuit located within 2 meters of the KSU is required. A
separate AC outlet is necessary for each KSU.
Meeting established environmental standards maximizes the life of the system.
Be sure the site is NOT :
In direct sunlight or in hot, cold or humid places.
In dusty areas or in areas where sulfuric gases are produced.
In places where shocks or vibrations are frequent or strong.
