Chassis Grounding

For information on grounding the chassis, see the "Installing the Ground Connection" section.


Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Statement 1015

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means by security. Statement 1017

Warning No user-serviceable parts inside. Do not open. Statement 1073

Warning This equipment needs to be grounded. Use a green and yellow 12 to 14 AWG ground wire to connect the host to earth ground during normal use. Statement 242

Warning The importance of proper grounding cannot be overemphasized. It will minimize the potential for damage to your system and maximize safety at the system site. We recommend you consult a licensed electrician or your local electric utility company if you have any questions. Statement 269

Warning A ground wire must always be a single piece of wire. Never splice two wires together for a ground. Corrosion and weathering can lead to a poor connection at the splice, making the ground ineffective and dangerous. Statement 270

Warning Use copper conductors only. Statement 1025

Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040
