IMPORTANT SAFETY INSTRUCTIONS
GENERAL SAFETY
Danger: YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Performing the following procedures may expose you to hazards. These procedures should be performed by qualified technicians familiar with the hazards associated with this type of equipment. These hazards may include shock, energy, and/or burns. To avoid these hazards:
a)The tasks should be performed in the order indicated.
b)Remove watches, rings, and other metal objects.
c)Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no voltage or the expected voltage is present.
d)Wear eye protection, and use recommended tools.
e)Use double insulated tools appropriately rated for the work to be performed.
Caution: Performing maintenance and/or troubleshooting procedures may interrupt power to the loads, if battery reserve is not sufficient.
VOLTAGES
AC Input Voltages
Danger: This system operates from AC voltage capable of producing fatal electrical shock. AC input power must be completely disconnected from the branch circuits wiring used to provide power to the system before any AC electrical connections are made. DO NOT apply AC power to the system until all electrical connections have been completed and checked.
DC Input/Output Voltages
Danger: This system produces DC Power and may require battery to be connected to it. Although the DC voltage is not hazardously high, the rectifiers and/or battery can deliver large amounts of current. Exercise extreme caution not to inadvertently contact or have any tool inadvertently contact a battery terminal or exposed wire connected to a battery terminal. NEVER allow a metal object, such as a tool, to contact more than one termination or battery terminal at a time, or to simultaneously contact a termination or battery terminal and a grounded object. Even a momentary short circuit can cause sparking, explosion, and injury.
BATTERY
Danger: Correct polarity must be observed when connecting battery leads.
Danger: Special safety precautions are required for procedures involving handling, installing, and servicing batteries. Observe all battery safety precautions in this manual and in the battery instruction manual. These precautions should be followed implicitly at all times. Remove watches, rings, and other metal objects before connecting battery leads.
