10.5 OVER-TEMPERATURE SHUT DOWN
In case of failure of the cooling fan 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° ± 5°C, the AC output of the inverter is shut down temporarily. Buzzer alarm
will be sounded. The GREEN "POWER ON"LED (2, Fig 6.1) will remain lighted. The Status
LED on the GFCI (5C, Fig 6.1) will be OFF.
The unit will automatically reset after the hot spot has cooled down to 65° ± 5°C.
10.6 GROUND FAULT/ LEAKAGE PROTECTION
AC Output is supplied through NEMA5-20R Self Monitoring GFCI Duplex Receptacle (5,
Fig 6.1). The GFCI will trip if there is 6 mA leakage/ Ground fault on the load side or, if
Neutral and Ground are bonded on the load side. When tripped, the Status LED (5C, Fig
6.1) will be switched OFF. Remove the cause of tripping. Switch ON the inverter if OFF
and then, press the "Reset Button" (5A, Fig 6.1) on the GFCI to reset (GFCI will not reset if
the inverter is OFF and there is no AC voltage on the internal Line Side of the GFCI). (Refer
to Section 8.5.2 for detailed information on the GFCI and it's operation)
10.7 REVERSE POLARITY AT THE DC INPUT TERMINALS
The Positive of the battery should be connected to the Positive DC input terminal of
the inverter (9, Fig 6.1) and the Negative of the battery should be connected to the
Negative DC input terminal of the inverter (8, Fig 6.1). A reversal of polarity (the Positive
of the battery wrongly connected to the Negative DC input terminal of the inverter and
the Negative of the battery wrongly connected to the Positive DC input terminal of the
inverter) will blow the external / internal DC side fuses. If the DC side fuse is blown, the
inverter will be dead. Green LED marked "POWER ON" (2, Fig 6.1) and the Status LED
on the GFCI (5C, Fig 6.1) will be switched OFF and there will be no AC output.
i
INFO
Reverse polarity connection is likely to damage the DC input circuitry. The
internal fuse(s) should be replaced with the correct size of fuse shown under
specifications. If the unit does not work after replacing the fuse(s), it has been
permanently damaged and will require repair / replacement (Please read
Section 11 - “Troubleshooting Guide” for more details).
i
INFO
Un inversement des polarités va probablement endommager les circuits
d'entrée CC. Il faut remplacer le(s) fusible(s) avec un/des fusible(s) d'une taille
pareille. Si après l'installation, l'appareil ne marche pas, c'est qu'il soit endom-
magé en permanence et aura besoin d'une réparation ou un remplacement
(Pour des renseignements supplémentaires, veuillez regardez à la Section 11 -
«Guide de Dépannage»).
