Electrical installation
NOTE:
- This device was designed to drive one or two Oblò
instrument. If you connect other instruments note that
the output current limit is 0.45 Amps.
- The power supply can be taken either from a line that
remains energized during engine start (ie master bus)
or from a line that remains off during engine start.
- The power-on switch on pin#3 is necessary to turn off
the Oblò or other connected instruments, because from
pin#3-6 is always present the voltage of the internal
battery.
- Complete the wiring harness and connector installation
prior to attaching the connecctor to the device. This is
essential to ensure the wires do not inadvertently short
together during installation (remember that the internal
battery of the device is ready to deliver output power
even when the aircraft electrical system is in the off
state).
- The warning led on pin#5 is used for eventual error
indications (ie battery fault, temperature outside
operating range...).
- Insert a 2 amp circuit breaker to the +12V power lead
(pin#1).
CAUTION:
Voltage peaks on the supply line that
exceeds the operating limits (20V) can damage the
device.
