105.4 Battery Cabinet Voltage Check and DC Fuse Installation
Note:Thisprocedureappliestoa36batterysystem.Fewerstepsmayberequireddependingonthenumberof
batteries in the system.
Important: Always observe proper polarity when taking battery voltage measurements.
1. Usingadigitalvolt-ohmmeter(DVM),checkforcorrectnominalbatteryvoltagebetweenrightsideoffuseblock
F1andleftsideofbatterycabinetterminalblockTB2(NEG-).Checkforcorrectvoltageineachbatterycabinet.
2. Identify the battery cabinet furthest from the inverter and install battery Fuse F1. Observing proper polarity, use
DVMtocheckforcorrectbatteryvoltagebetweenbatterycabinetterminalblockleftsideTB2(NEG-)andTB4
(POS+).Inaneightbatterysystem,proceedtoSection105.5.
3. Identify next battery cabinet in line. Observing proper polarity, use DVM to check for correct battery voltage be-
tweennextbatterycabinetterminalblockleftsideTB1(NEG-)andTB3(POS+).
4. Install battery Fuse F1. Observing proper polarity, use DVM to check for correct battery voltage between battery
cabinetterminalblockleftsideTB2(NEG-)andTB4(POS+).Ina16or24batterysystem,proceedtoSection
105.5
5. Identify last battery cabinet in line. Observing proper polarity, use DVM to check for correct battery voltage be-
tweenlastbatterycabinetterminalblockleftsideTB1(NEG-)andTB3(POS+).
6. Install battery Fuse F1. Observing proper polarity, use DVM to check for correct battery voltage between battery
cabinetterminalblockleftsideTB2(NEG-)andTB4(POS+).
