If batteries are being replaced, only use the same manufacturer and battery type and
rating as the battery removed. When the bus bars connecting the batteries are
removed, be careful to avoid dropping bolts or shifting the bus bars so that they might
short across adjacent battery terminals. We recommend using a piece of electrical
insulating paper (for example, “Nomex”) as a temporary shield between the bus bars
during service.
It is very important that only one tray at a time be extended from the cabinet. If more
than one tray is extended, the cabinet can become unstable and topple over.
After each tray is installed or serviced, it must be fully inserted and secured using the
supplied threaded fasteners before attempting to install or service another tray.
If the trays are to be removed, always remove the highest tray first. The battery trays
are very heavy and it will be necessary to use a lifting device to support the trays as
they are removed. When the trays are to be reinstalled, use the procedure in the
following paragraph.
The battery trays are very heavy and it will be necessary to use a lifting device to
support the trays as they are installed. Do not take away the external support until the
extension limit tabs on the upper sides of the battery tray are inserted past the notches
on the upper edge of the battery shelf (see
Figure 8
). Always install the lowest battery
tray first. After it is inserted fully into the support shelf, secure the tray with the supplied
threaded fasteners. After all of the trays are reinstalled and secured, reconnect the
cables using the markings as a guide.

WARNING
Never connect the two cables from a battery tray or from a battery string (two trays)
together as severe damage will occur, resulting in fire and/or injury. Battery connections
should only be made by a person wearing eye protection. It is advised that eye wash be
available. If there are any doubts about the proper connections, do not proceed.
