Operating Power
The LSM-2020 operating power input accepts either 12 Vdc or 24 Vdc and tolerates voltage over the
range of 6 to 32 Vdc. Operating power must be of the correct polarity. Although reverse polarity will not
cause damage, the LSM-2020 will not operate. Operating power terminals are listed in Table 8-1.
It is recommended that a fuse be added for additional protection for the wiring to the battery input of the
LSM-2020. A Bussmann ABC-7 fuse or equivalent is recommended.

Analog Outputs
The LSM-2020 has three sets of analog output contacts: AVR control, GOV control, and Load Share Line.
The AVR control output contacts provide remote control of the generator voltage setpoint. The GOV
control output contacts provide remote control of the generator speed (RPM) setpoint. The generator
uses the measured LS (Load Share Line) output to calculate the per unitized average load level, and
uses that as the set point for its kW controller. Analog input terminals are listed in Table 8-2.
