• The 48-300W Modular Switched Mode Rectifier System uses more than one live circuit. DC power may
be present at the outputs even if the system is disconnected from the mains supply.
• In high ambient temperature conditions, the surface of the shelf can be very hot to the touch.
• Battery installation and servicing should be done or supervised by personnel knowledgeable about
batteries and their safety procedures.
• Be extra cautious when connecting or adjusting battery cabling. An improperly connected battery cable
or an unconnected battery cable can result in arcing, fire or possible explosion.
• Use new batteries when installing a new unit. Verify that they are all the same battery type with identical
date codes.
• Always replace batteries with ones of identical number, type and rating. Never install old or untested
batteries. One sealed lead-acid battery is rated to a maximum voltage of 12Vdc.
• A battery that shows signs of cracking, leaking or swelling must be replaced immediately by authorized
personnel using a battery of identical type and rating.
• Keep the chassis area clear and dust-free during and after installation.
• Keep walkways free of tools to ensure that others cannot fall over them.
• Do not work on the unit or connect or disconnect cables during periods of lightning activity.
• A battery can present a risk of electrical shock and high short-circuit current. The following precautions
should be observed when working on batteries:

Remove watches, rings, or other metal objects.
 Use tools with insulated handles.
 Wear rubber gloves and boots.
 Do not lay tools or metal parts on top of batteries.
 Disconnect charging source prior to connecting or disconnecting battery terminals.
 Determine if the battery is inadvertently grounded, remove source from ground. Contact with any
part of a grounded battery can result in electrical shock. The likelihood of such a shock can be
reduced if such grounds are removed during installation and maintenance (applicable to equipment
and remote battery supplies not having a grounded supply circuit).
• Never let live battery wires touch the 48-300W Modular Switched Mode Rectifier System, the enclosure
or any other metal objects. This can cause a fire or explosion.
• Never dispose of batteries in a fire or furnace. The batteries may explode. Follow the manufacturer’s
directions and check with your local jurisdictions for safe battery disposal.
• Before plugging the batteries to the 48-300W Modular Switched Mode Rectifier System, make sure the
polarity is correct.
• If the batteries have been in storage for more than 3 months, recharge them for at least 24 hours then
test them with a load before installation.
