Electrical Safety
WARNING:
Hazardous Voltages are present at the input of power systems. The output from
rectifiers and from batteries may be low in voltage, but can have a very high current capacity that
may cause severe or even fatal injury.
When working with any live battery or power system, follow these precautions:
 Never work alone on any live power system; someone should always be close enough to come to your aid.
 Remove personal metal items such as rings, bracelets, necklaces, and watches.
 Wear complete eye protection (with side shields) and clothing protection.
 Always wear gloves and use insulated hand tools.
WARNING:
Lethal Voltages are present within the power system. Parts inside the unit may still be
energized even when the unit has been disconnected from the AC input power. Check with a meter
before proceeding. Do not touch any uninsulated parts.
 A licensed electrician should be used in the installation of any unit.
 Always disconnect the unit from the supply, batteries and loads before performing maintenance or cleaning.
 If the unit is hot-swappable, simply remove it from the shelf for any maintenance or cleaning.
 Always assume that an electrical connection is live and check the connection relative to ground.
 Be sure that neither liquids nor any wet material come in contact with any internal components.
 Do not operate this unit outside the input and output ratings listed on the unit nameplate.
 Do not use this unit for any purpose not described in the operation manual.
Mechanical Safety
 This unit or parts of the unit may get very hot during normal operation, use care when working nearby.
 Do not expose equipment to rain or snow. Always install in a clean, dry location.
 Do not operate equipment if it has received a sharp blow, been dropped, or otherwise damaged in any way.
 Do not disassemble this unit. Incorrect re-assembly may result in a risk of electric shock or fire.
Battery Safety
WARNING:
Follow all of the battery manufacturer’s safety recommendations when working with or
around battery systems. DO NOT smoke or introduce a spark or open flame in the vicinity of a
battery. Some batteries generate explosive gases during normal battery operation.
 To reduce risk of arc, connect and disconnect the battery only when the unit is off.
 If it is necessary to remove battery connections, always remove the grounded terminal from the battery first.
 Remove personal metal items such as rings, bracelets, necklaces, and watches.

Always wear rubber gloves, safety glasses, and a rubber lined vest/apron when working near a battery.
 Have plenty of fresh water and soap nearby in enclosure the battery electrolyte contacts skin, clothing, or
eyes.
 If the battery electrolyte contacts skin or clothing, wash immediately with soap and water.
 If the electrolyte enters the eye, immediately flood the eye with running cold water for at least ten (10)
minutes and seek medical attention immediately.

Do not drop metal on a battery. A spark or short-circuit could occur and could cause an explosion.
