SECTION 9 | Operation
!
ATTENTION!
Veuillez noter que l'interrupteur ON/OFF ne gère pas le circuit d'entrée de
batterie à haute puissance. Certaines parties du circuit de côté CC seraient
encores actives même si l'onduleur a été fermé. Alors, il faut déconnecter
tous les côtés CC et CA avant de travailler sur n'importe quel circuit connecté
à l'onduleur.
When the inverter is switched ON, the Green LED marked "POWER" (2, Fig 6.1a) 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 (6, Fig 6.1a) and at the AC output terminals for hardwiring (13, Fig 6.1b). The Green
indicator light on the GFCI will be lighted.
Switch on the AC load(s). The Green LED marked "POWER" (2, Fig 6.1a) 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
One thermostatically controlled cooling fan (18, Fig 6.1c) has been provided for forced air
cooling. Temperature of a critical hot spot inside the inverter (Power Transformer T6) is
monitored to activate the fan and the over temperature shut-down. When the temperature
of this hot spot reaches 55°C ± 3°C, the fan is switched ON. The fan will be automatically
switched OFF once the hot spot cools down to 45°C ± 3°C. Please note that the fan may not
switch 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 LED marked
"POWER" (2, Fig 6.1a) and the Green indication light on the GFCI will be lighted. Please see
Section 10 "Protections" and Section 11 "Troubleshooting Guide" for symptoms of abnor-
mal operation.
