Important Safety Instructions—Save These Instructions
WARNING! The mounting shelves are not intended to support more
than one battery pack. Do not stack multiple battery packs on a single
set of mounting shelves. Failure to follow this warning may lead to
product damage and/or a risk of personal bodily harm.
Use caution when lifting Battery Packs. Because of the considerable weight of all Rackmount
Battery Packs, at least two people should assist in lifting and installing them.
36V and 72V Battery Packs and UPS systems use identical power cables and plugs; make
certain that your Battery Packs and UPS use the same DC voltage before connecting them.
•Suggested mounting procedures are for common rack types and may not be appropriate for all rack
configurations. User must determine the fitness of rack- and wallmount hardware and procedures
before mounting.
When connecting multiple Battery Packs to a single UPS, the Battery Packs should be approximately
the same age.
It is normal for sparks to occur inside external battery connectors during final battery connection.
Do not unplug external batteries from the UPS while the UPS is operating on battery power, due to
the possibility of dangerous arcing.
There are no user-serviceable parts inside the Battery Packs. Do not open the Battery Packs for any reason.
Battery Replacement must be performed by factory authorized service personnel. Because batteries
present a risk of electrical shock and burn from high short-circuit current, observe proper precautions.
Unplug the Battery Pack from the UPS before performing battery replacement. Do not short or bridge
battery terminals with any object. Use tools with insulated handles. Remove metal objects such as
watches and rings before working with batteries. Do not open batteries. Replace batteries only with
sealed lead-acid batteries of the same number, type, voltage and amp hour capacity.
Do not dispose of batteries in a fire. The batteries are recyclable. Proper disposal of batteries is required;
refer to your local codes for disposal requirements. In the USA only, you may call 1-800-SAV-LEAD
(1-800-728-5323) for complete recycling information.
