Pilot’s Operating Manual
STATIC INVERTERS
Two 1500VA, 115V, 400 Hz. main static inverters, designated No. 1 and No. 2, are installed in the rear
equipment bay. Under normal operating conditions, these main inverters provide power to the airplane’s
AC busbars. A 250VA, 115V, 400Hz. standby inverter is installed in the rear equipment bay to power
essential AC services in the event of failure of both main inverters.
Starting No. 1 Inverter
Momentarily selecting INV 1 switch to the START position causes the following actions:
• Energize No. 1 inverter and connect its output to XS 1 busbar.
• Busbars XE and XS 2 will be supplied from XS 1 via the auto transfer circuit.
• The following annunciators will extinguish: XS 1 FAIL, INV 1 FAIL, XE FAIL and XS 2 FAIL. The
red MWS master warning lamps will also cease to operate.
• Annunciator INV 2 will remain illuminated.
Starting No. 2 inverter
With the No. 1 inverter on-line, momentarily selecting the INV 2 switch to START causes the following
actions:
• Energizes No. 2 inverter.
• Disconnect busbar XS 2 from the output of No. 1 inverter.
• Connect No. 2 inverter output to XS 2 busbar.
• INV 2 FAIL annunciator and the ELECT repeater annunciator to go out.
Failure Of a Main Inverter
Failure of one main inverter results in the related INV FAIL annunciator and ELECT repeater to
illuminate. The auto transfer circuit connects the remaining main inverter to all three busbars.
Failure Of Both Main Inverters
Provided the STBY INV switch is selected to ARM, failure of both main inverters results in the following
actions:
• Energizes the standby inverter and connect its output to XE busbar.
• The STBY INV ON annunciator will illuminate.
• The XS 1, INV 1, XS 2 and INV 2 FAIL annunciators will illuminate, together with the ELECT
repeater.
NOTE: If the standby inverter fails while operating, the XE FAIL annunciator will illuminate and the
MWS master warning lamps will flash.
