over-temperature Shut Down
In case of failure of the cooling fans or in the case of inadequate heat removal due to
higher ambient temperatures / insufficient air exchange, the temperature inside the
unit will increase. The temperature of a critical hot spot inside the inverter is monitored
and at 203°f / 95°C, the AC output of the inverter is shut down temporarily. Buzzer
alarm will be sounded. The GREEN "Power oN"LED (2) will remain lighted. The GREEN
indication light on the GfCI will be off.
The unit will automatically reset after the hot spot has cooled down to 158°f / 70°C.
internal Dc Side Fuses
The following DC side fuses have been provided for internal protection of the DC input
side. The fuses are 32V, Automotive Type Blade fuses, Type "ATC" by Cooper Bussmann
or equivalent:
PST-1500-12: 5 pieces of 40A in parallel = 200A total
PST-1500-24: 5 pieces of 20A in parallel = 100A total
PST-2000-12: 6 pieces of 40A in parallel = 240A total
PST-2000-24: 6 pieces of 20A in parallel = 120A total
Reverse Polarity at the Dc input terminals
The Positive of the battery should be connected to the Positive DC input terminal of the
inverter and the Negative of the battery should be connected to the Negative DC input
terminal of the inverter. A reversal of polarity (the Positive of the battery wrongly con-
nected to the Negative DC input terminal of the inverter and the Negative of the bat-
tery wrongly connected to the Positive DC input terminal of the inverter) will blow the
external / internal DC side fuses. If the DC side fuse is blown, the inverter will be dead.
The Status LED (2) and the GREEN indication light on the GfCI will be switched off and
there will be no AC output.

inFo
Reverse polarity connection is likely to damage the DC input circuitry. The internal fuse(s)
should be replaced with the same size of fuse(s) used in the unit. If the unit does not work
after replacing the fuse(s), it has been permanently damaged and will require repair /
replacement (Please read Section 11 - “Troubleshooting Guide” for more details).
!
cAUtion!
Damage caused by reverse polarity is not covered by warranty! When making battery
connections on the input side, make sure that the polarity of battery connections is correct
(Connect the Positive of the battery to the Positive terminal of the unit and the Negative
of the battery to the Negative terminal of the unit). If the input is connected in reverse
polarity, DC fuse(s) inside the inverter / external fuse will blow and may also cause
permanent damage to the inverter.
