Safety Admonishments Definitions
Definitions of the safety admonishments used in this document are listed under “Admonishments Used in this Document” on page iv.
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
DC Input Voltages
DANGER!
This system operates from DC input voltage. Although the DC voltage is not hazardously high, the input power
can deliver large amounts of current.
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 converters 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.
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 to 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”.
