ISSUE
When switched ON, the
Green LED marked "POWER"
(2, Fig 6.1) does not light.
Buzzer is OFF. There is no AC
output voltage. Green indica-
tion light on the GFCI is OFF.
Low AC output voltage
(< 120VAC but > 80VAC)
(No buzzer alarm).
AC output voltage is available.
Buzzer alarm is sounded at no
load or, when load is switched
ON. The Green LED marked
"POWER" (2, Fig 6.1) is
lighted. Indication light on the
GFCI is Green.
There is no AC output voltage.
Buzzer alarm is sounded
at no load or when load is
switched ON. The Green LED
marked "POWER" (2, Fig 6.1)
is lighted. GREEN indication
light on the GFCI is OFF. There
is no AC output.

Troubleshooting Guide
POSSIBLE CAUSE
There is no voltage at the
DC input terminals
Polarity of the DC input
voltage has been reversed
that has blown the exter-
nal / internal DC side fuses
(Note: Reverse polarity
may cause permanent
damage. Damage caused
due to reverse polarity is
not covered by warranty)
• AC load is exceeding
Surge Overload of 175%
for PST-2000 or 200%
for PST-1500
• Load is approaching
Surge Overload of 175%
for PST-2000 or 200%
for PST-1500 during
lower DC input voltage
• Low DC input voltage
alarm
• DC input voltage is 10.7
± 0.1V or lower but
>10V ± 0.1V for PST-
1500-12 / PST-2000-12
• DC input voltage is
21.4 ± 0.2V or lower but
> 20V ± 0.2V for PST-
1500-24 / PST-2000-24
• AC output voltage has
been shut down due to
low DC input voltage
• DC input voltage is 10
± 0.1V or lower for PST-
1500-12 / PST-2000-12
• DC input voltage is 20
± 0.2V or lower for PST-
1500-24 / PST-2000-24
REMEDY
• Check the continuity of the battery
input circuit.
• Check that the internal/external battery
fuses are intact. Replace if blown.
• Check that all connections in the battery
input circuit are tight.
• Check external and internal fuses. Replace
fuses. If unit does not work, call Technical
Support for repair.
• Check that the battery is fully charged.
Recharge, if low.
• Check that the battery cables are thick
enough to carry the required current over
the required length. Use thicker cables, if
required.
• Tighten connections of battery input circuit.
• Reduce load.
• Check that the battery is fully charged.
Recharge, if low.
• Check that the battery cables are thick
enough to carry the required current over
the required length. Use thicker cables, if
required.
• Tighten connections of the battery input
circuit.
• Check that the battery is fully charged.
Recharge, if low.
• Check that the battery cables are thick
enough to carry the required current over
the required length. Use thicker cables, if
required.
• Tighten connections of the battery input
circuit.
• The AC output voltage will switch ON au-
tomatically when the DC input voltage rises
to 11.5V ± 0.1V or higher for PST-1500-12
/ PST-2000-12 or, 23V ± 0.2V or higher for
PST-1500-24 / PST-2000-24.
