10.2 WARNING ALARM - LOW DC INPUT VOLTAGE
The voltage at the DC input terminals will be lower than the voltage at the battery ter-
minals due to voltage drop in the battery wires and connectors. The drop in the voltage
at the DC input terminals of the inverter could be due to lower battery voltage or due
to abnormally high drop in the battery wires if the wires are not thick enough (Please
see Section 8.4.3 “Connection from Batteries to the DC Input Side – Sizing of Cables
and Fuses”). If the voltage at the DC input terminals drops to 42.0V ± 0.5V or lower, a
buzzer alarm will be sounded. The Green LED marked "POWER" / "POWER ON" (2 in
Fig 6.1 for PST-1500-48 and 2 in Fig 6.2 for PST-600-48) and indication light on the GFCI
will continue to be lighted and the AC output voltage would continue to be available.
This warning buzzer alarm indicates that the battery is running low and that the in-
verter will be shut down after sometime if the voltage at the inverter terminals further
drops to 40.0V ± 0.5V or lower.
10.3 LOW DC INPUT VOLTAGE SHUT DOWN
If the voltage at the DC input terminals drops to 40.0V ± 0.5V or lower, the AC output is
shut down. Buzzer alarm is sounded. The Green LED marked "POWER" / "POWER ON"
(2 in Fig 6.1 for PST-1500-48 and 2 in Fig 6.2 for PST-600-48) will remain lighted. The
Green indication light on the GFCI will be OFF.
The unit will reset automatically when the DC input voltage rises to 46.0V ± 0.5V or higher.
10.4 HIGH DC INPUT VOLTAGE SHUTDOWN
If the voltage at the DC input terminals rises to 64.0V or higher, the AC output voltage
will be shut down temporarily. Buzzer alarm will be sounded. The Green LED marked
"POWER" / "POWER ON" (2 in Fig 6.1 for PST-1500-48 and 2 in Fig 6.2 for PST-600-48)
will remain lighted. The Green indicator light on the GFCI will be OFF. The unit will be
reset automatically when the voltage drops down to < 64.0V.
10.5 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 90°C
± 5°C, the AC output of the inverter is shut down temporarily. Buzzer alarm will be sounded.
The Green LED marked "POWER" / "POWER ON" (2 in Fig 6.1 for PST-1500-48 and 2 in Fig
6.2 for PST-600-48) 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 65°C ± 5°C.
10.6 GROUND FAULT / LEAKAGE PROTECTION
AC Output is supplied through NEMA5-20R GFCI Duplex Receptacle (5 in Fig 6.1 for
PST-1500-48 and 5 in Fig 6.2 for PST-600-48). In PST-1500-48, AC output is also supplied
through hardwiring (13 in Fig 6.1). The GFCI will trip if there is 5 to 6 mA leakage /
