• Keep tools away from walkways, where you and others might trip over them.
• Do not wear loose clothing or jewelry, such as earrings, bracelets, or chains that could get caught in the
chassis.
• Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Never attempt to lift an object that is too heavy for one person.
Maintain Safety with Electricity
Before working on a chassis, be sure the power cord is unplugged.
Warning
Be sure to read the
Regulatory and Compliance Safety Information
document before installing the security
appliance.
Follow these guidelines when working on equipment powered by electricity:
• Before beginning procedures that require access to the interior of the chassis, locate the emergency
power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can
act quickly to turn off the power.
• Do not work alone if potentially hazardous conditions exist anywhere in your work space.
• Never assume that power is disconnected; always check.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension
cables, frayed power cords, and missing safety grounds.
• If an electrical accident occurs:
• Use caution; do not become a victim yourself.
• Disconnect power from the system.
• If possible, send another person to get medical aid. Otherwise, assess the condition of the victim,
and then call for help.
• Determine whether the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
• Use the chassis within its marked electrical ratings and product usage instructions.
Prevent ESD Damage
ESD occurs when electronic components are improperly handled, and it can damage equipment and impair
electrical circuitry, resulting in intermittent or complete failure.
