IMPORTANT SAFETY INSTRUCTIONS
Safety Admonishments Definitions
Definitions of the safety admonishments used in this document are listed under “Admonishments Used in this
Document” on page 6.
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.
Voltages
AC Input Voltages
DANGER! This system operates from AC input 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. 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.
DC Output and Battery Voltages
DANGER! This system produces DC power and may have a battery source 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 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-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! 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.
WARNING! A battery can present a risk of electrical shock and high short circuit current. Servicing of
batteries should be performed or supervised only by properly trained and qualified personnel
knowledgeable about batteries and the required precautions.
The following precautions should be observed when working on batteries:
•Follow the recommended PPE requirements per the SDS for the battery to be used.
•Batteries are an energy source that can produce high amounts of electrical current.
•Remove watches, rings, and other metal objects.
•Eye protection should be worn to prevent injury from accidental electrical arcs.
•Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for
the work to be performed. Ensure that wrenches with more than one working end have only one
end exposed.
•Do not lay tools or metal parts on top of batteries.
•Verify that no current will flow when the battery is connected or disconnected by opening battery
disconnects (if available) or adjusting the system to match battery voltage.
•Risk of explosion if battery is replaced with an incorrect type or if polarity is reversed.
Recommended to replace batteries with the same manufacturer and type, or equivalent.
•Dispose of used batteries according to the instructions provided with the batteries. Do not dispose
of batteries in a fire. They may explode.
•Batteries may generate explosive gases during normal operation. Systems containing batteries
should never be installed in an airtight room or space. Only install in a ventilated environment.
•Batteries may contain sulfuric acid. If battery acid enters your eye, immediately flush your eye with
running cold water for at least 15 minutes. Get medical attention immediately. If battery acid
contacts skin or clothing, wash immediately with soap and water.
•Do not open or mutilate batteries.
•ALWAYS FOLLOW THE BATTERY MANUFACTURER’S RECOMMENDATIONS AND SAFETY
INSTRUCTIONS.

ALERT! Performing maintenance and/or troubleshooting procedures may interrupt power to the loads,
if battery reserve is not sufficient.
Personal Protective Equipment (PPE)
DANGER! ARC FLASH AND SHOCK HAZARD.
Appropriate PPE and tools required when working on this equipment. An appropriate flash protection
boundary analysis should be done determine the “hazard/risk” category, and to select proper PPE.
Only authorized and properly trained personnel should be allowed to install, inspect, operate, or maintain
the equipment.
Do not work on LIVE parts. If required to work or operate live parts, obtain appropriate Energized Work
Permits as required by the local authority, per NFPA 70E “Standard for Electrical Safety in the
Workplace”.
Hazardous Voltage
DANGER! HAZARD OF ELECTRICAL SHOCK.
More than one disconnect may be required to de-energize the system before servicing.
Handling Equipment Containing Static Sensitive Components
ALERT! Installation or removal of equipment containing static sensitive components requires careful
handling. Before handling any equipment containing static sensitive components, read and follow the
instructions contained in “Static Warning” on page 10.
Maintenance and Replacement Procedures
CAUTION! When performing any step in procedures that requires removal or installation of hardware,
use caution to ensure no hardware is dropped and left inside the unit; otherwise service interruption or
equipment damage may occur.
NOTE! When performing any step in procedures that requires removal of existing hardware, retain all
hardware for use in subsequent steps, unless otherwise directed.

STATIC WARNING
This equipment contains static sensitive components. The warnings listed below must be observed to
prevent damage to these components. Disregarding any of these warnings may result in personal injury
or damage to the equipment.
1. Strictly adhere to the procedures provided in this document.
2. Before touching any equipment containing static sensitive components, discharge all static
electricity from yourself by wearing a wrist strap grounded through a one megohm resistor. Some
wrist straps have a built-in one megohm resistor; no external resistor is necessary. Read and follow
wrist strap manufacturer’s instructions outlining use of a specific wrist strap.
3. Do not touch traces or components on equipment containing static sensitive components. Handle
equipment containing static sensitive components only by the edges that do not have connector
pads.
4. After removing equipment containing static sensitive components, place the equipment only on
static dissipative surfaces such as conductive foam or ESD bag. Do not use ordinary Styrofoam™or
ordinary plastic.
5. Store and ship equipment containing static sensitive components only in static shielding containers.
6. If necessary to repair equipment containing static sensitive components, wear an appropriately
grounded wrist strap, work on a conductive surface, use a grounded soldering iron, and use
grounded test equipment.
