1.2 General warning and cautions
• Read and follow all instructions included in this document.
• Only trained personnel are qualified to install or replace this equipment and its components.
• Use proper lifting techniques whenever handling equipment, parts, or batteries.
WARNING
You must read and understand the following warnings before installing the enclosure and its
component. Failure to do so could result in personal injury or death.
Before working with any live battery or power system, follow these precautions:
• Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
• Wear safety glasses with side shields at all times during the installation.
• Use insulated hand tools. Do not rest tools on top of batteries.
• Do not work alone under hazardous conditions.
• A licensed electrician is required to install permanently wired equipment. Input voltages can range
up to 480 Vac. Ensure the utility power is disconnected and locked out before performing any
installation or removal procedure.
• Ensure that no liquids or wet clothes come into contact with internal components.
• Hazardous electrically live parts inside this unit are energized from the batteries even when the AC
input power is disconnected.
1.3 Electrical safety
WARNING
Hazardous voltages are present at the input of power systems.
The DC output from rectifiers, though not dangerous in voltage, has a high short-circuit current
capacity that can cause severe burns and electrical arcing. Do not touch the output connections
or the bullet terminal in distribution panel when under power. Ensure that power has been
removed from the outputs before working on them.
The DC output from converters is a potentially hazardous voltage. Do not touch the output connections
when under power. Ensure that power has been removed from the outputs before working on them.
WARNING
Lethal voltages are present within the power system. Always assume that an electrical
connection or conductor is energized. Check the circuit with a voltmeter with respect to the
grounded portion of the enclosure (both AC and DC) before performing any installation or
removal procedure.
WARNING
High leak and touch current
Earth connection is essential before connecting the supply.
