Preparing for Installation Chapter 2 Installation Warning Only trained and qualified personnel should be allowed to install or replace this equipment. Warning Read the installation instructions before you connect the system to its power source. Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Warning Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage. Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. Warning To prevent the switch from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 113×F (45×C). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings. Warning The device is designed to work with TN power systems. Warning When installing the unit, the ground connection must always be made first and disconnected last. Catalyst 2900 Series XL Hardware Installation Guide 2-2 78-6461-04
