Alternate source	Backup source that steps in if the preferred source fails.
JBUS communication card	Internal card implementing the JBus protocol on a serial link to supply the user with
	system information.
Load	Device(s) or system(s) connected the Upsilon STS output.
Manual bypass	Q1BP, Q3 and Q2BP switches, accessible to the user, that may be used to directly
	supply the load from Source S1 or S2. The bypass enables servicing on the equipment
	without interrupting the supply of power to the load.
Normal mode	Operating mode during which the load is supplied by the preferred source.
Preferred source	Source selected as the normal source of power.
Relay communication card	Internal card implementing contacts to supply the user with system information.
Static switch	Electronic switch ensuring instantaneous switching.
