INVERTER AC OUPUT:
Pin B – AC Output 115VAC, 60Hz. Used for powering devices where terrestrial/utility power
designations are used, pin B can be connected as “Line” or “Hot”.
Pin C – AC Return 115VAC, 60Hz. Used for powering devices where terrestrial/utility power
designations are used, pin C can be connected as “Neutral”.
Note: Use of a circuit breaker on the AC output is optional. For the full
output of 250VA, a 2.5 Amp circuit breaker is sufficient. For convenience at
each AC outlet, individual circuit breakers of 1 to 3 amps each can be used.
If a single pole breaker is used, install the breaker on the wire from pin B. If
a double pole breaker is installed, route both pins B and C through the circuit
breaker.
INVERTER REMOTE ON/OFF CONTROL: (see section 4.2.1)
Pin E – Remote ON/OFF Control. Connecting this pin to either DC Negative or to aircraft
ground will enable the AC output of the inverter. By utilizing a switch between this pin and
ground or negative, it will allow remote on/off control of the unit. When unconnected (output
is OFF) this pin will have approximately 16 VDC present, internally limited to less than 3 mA.
If the inverter is to be enabled at all times, pin E can be connected to pin G.
Pin G – Remote ON/OFF Return. This pin is internally connected to pin D. Pin G may be used
as the return from an ON/OFF switch or left unconnected. It is recommended that pin G not
be connected directly to ground or 28V negative.
INVERTER FAULT INDICATION OUTPUT:
Pin F – Fault Indication Output. This pin can be connected to an external LED or status
monitoring device to indicated the operating status of the inverter. The inverter will provide
Fault indication when: Power Output capability has been exceeded, the output has been
short-circuited, the output is ground-faulted (GFI protection activated), or the inverter has
shut-down in over-temperature protection. The output is an open-collector transistor with a
weak pull-up to 28V (21K ohm) capable of sinking 100 mA.
