CAUTION!
Please note that the ON/OFF switch is not switching the high power battery
input circuit. Parts of the DC side circuit will still be alive even when the switch
is in the OFF position. Hence, disconnect the DC and AC sides before working
on any circuits connected to the inverter.
When the inverter is switched ON, the GREEN "POWER" / "POWER ON" LED (2, Fig. 6.1
for PST-1500-48 and 2 in Fig 6.2 for PST-600-48) will be lighted. This LED indicates that
the input section of the inverter is operating normally. Under normal operating condi-
tions, AC output voltage will now be available at the GFCI Duplex Receptacle (5, Fig 6.1
for PST-1500-48 and 5 in Fig 6.2 for PST-600-48) and at the Line "L" and Neutral "N"
terminals (15, 16 in Fig 6.1 for PST-1500-48) located inside the compartment containing
AC output terminals for hard-wiring (13, Fig 6.1 for PST-1500-48). The Green indicator
light on the GFCI (5d in Fig 6.1 for PST-1500-48 and 5d in Fig 6.2 for PST-600-48) will be
lighted.
Switch on the AC load(s). The GREEN "POWER" / "POWER ON" LED (2, Fig 6.1 for PST-
1500-48 and 2, Fig 6.2 for PST-600-48) and the indication light on the GFCI should remain
lighted for normal operation of the load.
9.2 POWERING ON THE LOADS
After the inverter is switched on, it takes a finite time to become ready to deliver full
power. Hence, always switch on the load(s) after a few seconds of switching on the
inverter. Avoid switching on the inverter with the load already switched on. This may
prematurely trigger the overload protection.
When a load is switched on, it may require initial higher power surge to start. Hence, if mul-
tiple loads are being powered, they should be switched on one by one so that the inverter is
not overloaded by the higher starting surge if all the loads are switched on at once.
9.3 TEMPERATURE CONTROLLED COOLING FAN(S)
PST-1500-48 has 2 cooling fans (located behind the air-exhaust openings 6, Fig 6.1).
PST-600-48 has one cooling fan behind fan air exhaust opening (6, Fig 6.2). The fans are
thermostatically controlled. Temperature of a critical hot spot inside the inverter is moni-
tored to activate the fans and the over temperature shut-down. When the temperature of
this hot spot reaches 55°C ± 3°C, the fans are switched ON. The fans will be automatically
switched OFF once the hot spot cools down to 45°C ± 3°C. Please note that the fan(s) may
not come on at low loads or if the ambient temperature is cooler. This is normal.
9.4 INDICATIONS FOR NORMAL OPERATION
When the inverter is operating normally and supplying AC load(s), the GREEN "POWER" /
"POWER ON" LED (2, Fig 6.1 for PST-1500-48 and 2 in Fig 6.2 for PST-600-48) and the indica-
tion light on the GFCI will be lighted. Please see Section 10, "Protections" and Section 11
"Troubleshooting Guide" for symptoms of abnormal operation.
