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.  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. 

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 on the Static Warning Page.
