SECTION 9 |
9.1 SWITCHING THE INVERTER ON/OFF
Before switching on the inverter, check that all the AC loads have been switched OFF.
The ON/OFF switch (1, Fig 6.1) on the front panel of the inverter is used to switch ON
and switch OFF the inverter. This switch operates a low power control circuitry, which in
turn controls all the high power circuitry. Optional Remote Control Model RC-300 may
also be used for ON/OFF control.
!
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 ON" LED (2, Fig. 6.1) will be
lighted. This LED indicates that the input section of the inverter is operating normally.
Under normal operating conditions, AC output voltage will now be available at the GFCI
Duplex Receptacle (5, Fig 6.1) and at the Line "L" and Neutral "N" terminals (15, 16 of
Fig 6.1) located inside the compartment containing AC output terminals for hard-wiring
(13, Fig 6.1). The Green indicator light on the GFCI will be lighted.
Switch on the AC load(s). The GREEN "POWER ON" LED (2, Fig 6.1) 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 FANS
2 cooling fans (located behind the air-exhaust openings 6, Fig 6.1) are thermostatically
controlled. Temperature of a critical hot spot inside the inverter is monitored 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 fans may not come on at
low loads or if the ambient temperature is cooler. This is normal.
