is 200 VAC which is input to the 200 VDC power supply. (See CAUTIONS on
page 5-9 regarding the use of the VOLTAGE SELECT switch.)
Inverter.
switched to 12 VDC and a 12 VDC supply is connected to the 12 VDC
connector on the connector panel. The inverter output is 115 VAC which
provides the main AC input power for the TPU. When using +12 VDC to
power the TPU, the VOLTAGE SELECT switch must be switched to 115V.
Baffle fan.
