2.5.6 Protections
The Global LF series inverter is equipped with extensive protections against various harsh situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after fault)
Back feeding protection
When over temperature / over load occur, after the fault is cleared, the master switch has to be reset to restart
the inverter.
The low battery voltage trip point can be customized from a defaulted value of 10VDC to 10.5VDC thru
SW1 on the DIP switch.
The inverter will go to over temp protection when the heat sink temp. ≥105ºC (221℉), and go to Fault
(shutdown Output) after 30 seconds. The switch has to be reset to activate the inverter.
The Global LF series Inverter has back feeding protection which avoids presenting an AC voltage on the AC
input terminal in inverter mode.
After the reason for the fault is cleared, the inverter must be reset to start working.
Peak Current 50 Amp, duration 1 Second of peak and the 3 cycle RMS value is 100Vac.
2.5.7 Remote Control
Apart from the switch panel on the front (or top) of the
inverter,
an extra switch panel connected to the RJ11 port at the
DC side of the inverter thru a standard telephone cable
can also control the operation of the inverter (sold
separately Part # REMOTELF).
If an extra switch panel is connected to the inverter via
“remote control port”, together with the panel on the
inverter case, the two panels will be connected and
operated in parallel.
Whichever first switches from “Off” to “Power saver off”
or
“Power saver on”, it will power the inverter on.
If the commands from the two panels conflict, the inverter will operate according to the following priority:
Power saver on> Power saver off> Power off
Only when both panels are turned to the “Unit Off” position, will the inverter be powered off.
The Max length of the cable is 10 meters.
WARNING
Never cut the telephone cable when the cable is attached to inverter and battery is connected to the inverter.
Even if the inverter is turned off, it will damage the remote PCB inside if the cable is short circuited during
cutting.
