Important Safety Instructions
General Safety
DANGER!
YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Danger
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.
Voltages
AC Input Voltages
DANGER! This system operates from AC input voltage
capable of producing fatal electrical shock. AC input
Danger
power must be completely disconnected from the
branch circuits wiring used to provide power to the
system before any AC electrical connections are made.
Follow local lockout/tagout procedures to ensure
upstream branch circuit breakers remain de-energized
during installation. DO NOT apply AC input power to
the system until all electrical connections have been
completed and checked.
Spec. No: 582127000100, 582127000103
Model No: 7100
DC Output and Battery Voltages
DANGER! This system produces DC power and may
have a battery source connected to it. Although the DC
Danger
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 an output terminal or
battery terminal or exposed wire connected to an
output terminal or 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.
DANGER! Follow local lockout/tagout procedures to
ensure DC branch circuit protection devices remain de-
Danger
energized during installation at loads, as required.
Battery
Refer to the battery manufacturer documentation for specific
battery safety instructions. The following are general guidelines.
WARNING! Correct polarity must be observed when
connecting battery leads.
Warning
WARNING! Special safety precautions are required for
procedures involving handling, installing, and servicing
Warning
batteries. Observe all battery safety precautions in this
manual and in the battery instruction manual. These
precautions should be followed implicitly at all times.
