Switching on / off using the optional remote on / off Control
An optional corded Remote Control Model, No. RC-15, is available to enable switching
on and off from a distance of 6 Mtr. The remote on / off control comeswith 6 Mtr. of wire.
One end of the remote control is plugged into the 6 position modular jack (9) provided
on the inverter.
To use the remote control, the inverter is first required to be switched
on from the on / off switch on the front panel.
Now, the inverter can be toggled between
off / on conditions by pressing the push button on the remote control.
The LED on the remote control will light when the inverter is in the on condition
No load draw (idle current)
When the on / off switch is turned on, all the circuitry inside the inverter becomes alive
and the AC output is made available. In this condition, even when no load is being supplied
(or, if a load is connected but has been switched off), the inverter draws a small amount
of current from the batteries to keep the circuitry alive and ready to deliver the required
power on demand. This is called the idle current or the no load draw. Hence, when the
load is not required to be operated, turn off the on / off switch on the inverter to prevent
unnecessary current drain from the battery.
NOTE:
When the inverter is turned off using the optional Remote Control RC-15, only
the final output section is turned off. The rest of circuits are still in standby condition.
Hence, even in this off condition, there will be a no load current. Therefore, to prevent
any drain from the battery, switch of the inverter from the on/off switch provided on the
front panel of the inverter.
PROTECTIONS AGAINST ABNORMAL CONDITIONS
The inverter has been provided with protections detailed below.
Low DC input voltage warning alarm.
The voltage at the DC input terminals will be lower
than the voltage at the battery terminals due to the voltage drop in the battery cables 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 cables if the cables are not
thick enough (Please read under
“Installation – Connection from the batteries to the
DC input side of the inverter – cable and fuse sizes” on page 19)
If the voltage at the
DC input terminals falls below 10.5 V for 12V version or 21 V for 24V version, a buzzer
alarm will be sounded. The LED (2) will continue to be green and the AC output voltage will
continue to be available. This warning buzzer alarm indicates that the battery is running
low and that the inverter will be shut down after sometime if the voltage at the inverter
terminals further drops to 10 V for 12 V version or 20 V 24 V version.
