position, but no power is being supplied to a load, the inverter draws less
than ½ amp from the battery. This is low current draw. It would take more than
a week to discharge a 100 ampere hour battery at this rate depending on the
age of the battery. For safety disconnect the RPPD1500 from the battery
when not in use.
Operating Indicators
:
Indicators on the output end of the unit show the inverters power status and
alarms for conditions that could cause it to shut down.
When the inverter power is on, the voltage input and power output indicators,
automatically toggle between input and output values at three-second
intervals. The three LEDs indicate the mode the meter is in and the three
digits indicate the voltage or power value.
NOTE: Once the inverter power output value has exceeded 999 watts, the
display will indicate kilowatts. Example: 1.25 kilowatts = 1250 watts.
Current Overload Protection
:
If the inverter is overloaded, it will shut down to protect itself. The meter will
flash (OLP) to indicate Overload Protect. To restore normal operation,
disconnect the excessive load and turn the unit off and on again using the
Power Button.
Short Circuit Protection
:
If the AC output of the inverter is short circuited for one second or more,
it will shut down to protect itself. The meter will flash (OPP) to indicate Short
Circuit Protect and an alarm will sound. To restore normal operation,
disconnect the short circuit and turn the unit Off and On again using the
Power Button.
Low Voltage Protection
:
If the DC input voltage drops below the alarm threshold of 10.5V the meter will
flash (LUP) to indicate Low Voltage Protection, but the unit will continue to
operate. If the input voltage drops to 10.0V or less, the inverter will shut down
to protect itself, the meter will continue to flash (LUP), and an alarm will
sound. To restore normal operation, return the DC input voltage to at least
12V. The inverter will automatically return to normal operation.
