* Once every year all the batteries should be inspected to ensure all connections are tight and re-
torqued to the requirements outlined in the Battery Installation section.
11.2
Battery Replacement
Lite-Minder is a UL approved and listed component with exact battery requirements. Failure to
replace the batteries with the exact same type will VOID the UL approval. For battery replacement,
please call the service number listed in the warranty section so that the unit performs as it was
intended.
WARNING – Only qualified personnel that is familiar with AC and DC installation techniques and
codes (such as an electrician) should perform the removal and replacement.
WARNING – Remove all rings, watches, and other jewelry before doing any electrical service or
installation work. Always wear protective clothing and appropriate personal protective
equipment (PPE) that is suitable such as eye protection, etc. when working with batteries.
WARNING - Batteries contain tremendous energy and can explode if short circuited. Precautions
should be taken to eliminate possible short circuits.
WARNING – Batteries contain lead. Follow all local and state requirements for battery disposal.
Please dispose of properly by recycling.
TIP
– Discharging the batteries by letting the Lite-Minder run on Battery Power can be beneficial for
several reasons. First, it verifies that the batteries need replacing if it does not make 90 minutes of
discharge time. Second, it depletes the battery which reduces the fault current available at the
batteries terminals. A completely discharged battery that ran to LVD still has fault current available –
just not nearly as much. By running the battery to LVD, the available fault current would be
substantially less and safer if an inadvertent short circuit were to happen during the removal or
transportation process to the recycling facility.
To remove the batteries, shut the unit completely down by turning off the System On/Off switch and
remove AC power Feed source by turning off the input circuit breaker.
Remove the quick connect/dis-connect connectors attached to each battery and carefully slide the
battery forward and then remove by lifting. Do not remove the bolts from the batteries – dis-connect
the Anderson Power Pole connectors for battery removal.
DANGER
– The worst thing that can happen when removing or installing batteries is an inadvertent
short circuit. All means must be taken to ensure that all lugs are secure and insulated after removal
from the batteries post. Batteries contain tremendous short circuit energy and are on the magnitude
of thousands of amps. When a short circuit occurs, it first creates a very loud shock wave similar to
a shotgun blast. If the short circuit creates a welded lug so that the short circuit remains conducting
current, the battery may explode.
Extreme danger and bodily injury can be caused by primary and secondary effects of the short
circuit. Primary effects would be burns, vision or hearing loss. Secondary effects could be falling off
a ladder or sustaining injuries not created by the battery itself.
DANGER – DO NOT TOUCH BATTERIES UNLESS TRAINED OR KNOWLEDGEABLE AND KNOW
THE HAZZARDS!
WARNING
– Always use the correct tools with insulated handles and wear the appropriate personal
protective equipment (PPE) required for battery work.
To install new batteries, see section 5.0 Battery and DC Connections.
