Definitions of the safety admonishments used in this document are listed under “Admonishments Used in this
Document” on page 4.
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. Check for voltage with both AC and DC voltmeters prior to
making contact.
d)
Wear eye protection.
e)
Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for
the work to be performed.
DC Voltages
DANGER! THIS SYSTEM CONTAINS BATTERIES
Although the DC voltage is not hazardously high, the 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.
