Installing Batteries
NOTE: ThefollowingprocedureappliestostandardType“S”maintenance-freeLead-Calciumbatteries.LSNsystemsspecied
with long-life Lead-Calcium (Free-Standing Type “G”) or wet-cell Nickel-Cadmium (Type” N”) batteries are supplied with Wiring
Diagrams in the documentation package. Make sure all switches and circuit breakers are in the "OFF" position.
IMPORTANT:Insureallterminalblockandcableconnectionsaretightenedaccordingtothepropertorquespecicationslistedon
pages 17 and 19 of this manual.
CAUTION: Verify that proper polarity is maintained in the wiring between the battery and electronics cabinets.
CAUTION: DO NOT INSTALL FUSE(S) IN BATTERY CABINET FUSE BLOCK(S) AT THIS TIME.
CAUTION: Orient all batteries with the positive terminals to the right as shown in the diagrams that follow.
Carefully observe battery polarity when making inter-cell and inter-tier connections.
Preliminary Wiring:
1. InstallfuseblockcableBC1fromleftsideoffuseblocktoleftsideofcabinetterminalblockTB4(POS.+)ofeachbattery
cabinet.
2. InstallcableBC5fromleftsideofcabinetterminalblockTB2(NEG.-)ofeachbatterycabinet.Letcablehangtobottomof
battery cabinet.
3. Installinter-batterycabinetcables,BC6,toTB1(NEG-)andTB3(POS+)betweeneachbatterycabinet(ifapplicable).
4. Installbatterycabinettoelectronicscabinetcables,BC6,fromlastbatterycabinetTB1(NEG-)andTB3(POS+)toelectronics
cabinetDCInputNEGandPOSterminalblocks.
5. Connect inter-cabinet ground wires between all battery cabinets and electronics cabinet.
6. Route gray thermistor wire, which is coiled up and tie wire wrapped next to the DC input fuse, from electronics cabinet to one
of the battery cabinets. Attach it to one of the battery cables making sure the end of the gray wire is not touching either the
cabinet or any battery terminal. The chosen battery cabinet should be the one expected to get the warmest. The sensor at the
end of the wires will vary the charger settings depending on battery temperature.
Bottom Level Battery Installation
1. Placefourbatteriesinbottomofcabinet(s)withpositiveterminalsontherighthandside.
2. Attachthethreeinter-cellconnectors(BC3indiagram)betweencellsasshown.
3. ConnectBC5fromTB2NEG.onterminalblock(s)tonegativeterminalofbatteryatfrontleftposition.
Second Tier Battery Installation
1. Installsecondtiershelvesincabinet(s).Becarefultokeepshelffromtouchingbatteryterminals.
2. Placefourbatteriesonsecondtiershelfofcabinet(s)withpositiveterminalsontherighthandside.
3. Attachthethreeinter-cellconnectors(BC3)betweencellsasshown.
4. Connectinter-tiercable(s)(BC4)frompositiveterminalofbottomrightfrontcelltothenegativeterminalofsecondtierleftfront
cell as shown.
5a. For 24 and 36 battery systems, skip to “Third Tier Battery Installation” below.
5b. For8and16batterysystems,connectBC2cable(s)betweenpositiveterminalonupperrightfrontcelltotherightsideofFuse
Block F1 as shown.
Third Tier Battery Installation (24 and 36 Battery Systems Only)
1. Install third tier shelves in cabinets. Be careful to keep shelf from touching battery terminals.
2. Place four batteries on third tier shelf with positive terminals on the right hand side.
3. Attachthethreeinter-cellconnectors(BC3)betweencellsasshown.
4. Connectinter-tiercables(BC4)frompositiveterminalofsecondtierrightfrontcelltothenegativeterminalofthirdtierleftfront
cell as shown.
5. Connect BC2 cables between positive terminal on third tier right front cell to the right side of Fuse Block F1 as shown.
