To install new batteries, see Section 5.0 Battery and DC Connections.
11.2 Battery Replacement
LM/LMOPT Series 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 Section 9 Warranty so that the unit performs as it was intended.
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. Disconnect the Battery Connector from the PCB before
removing the inverter assembly. Remove the Inverter Assembly by removing the
4 nuts that attach it to the cabinet. Carefully remove the connectors from the
batteries, remove the battery brackets with a nut driver or socket extension and
then lift the batteries out of the cabinet.
TIP – If the batteries are to be replaced, discharging the batteries by running in
the
Inverter Mode can be beneficial. First, it verifies the batteries need
replacing if it does
not make 90 minutes of discharge time. Second, it depletes
the battery which reduces
the fault current. 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.
WARNING – Only qualified personnel that are familiar with AC and DC
installation techniques and codes 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.
WARNING – Always use the correct tools with insulated handles and wear the
appropriate personal protective equipment (PPE) required for battery work.
DO NOT TOUCH BATTERIES UNLESS TRAINED OR KNOWLEDGEABLE!
All means must be taken to prevent an inadvertent short circuit - ensure that
all lugs are secure and insulated after removal from the batteries post. 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 could include burns, vision or hearing
loss. Secondary effects could be falling off a ladder or other sustaining injuries.
