Note
It is not necessary to observe a certain phase rotation or even phase balance in three phase transmitters.
Additionally, the amplifier chassis can operate indefinitely (at a reduced power) with one or two of the
mains phases missing. The internal power supplies connected to each input will continue to operate pro-
vided the incoming mains power at that input falls within 190-300VAC.

Remove
the
cover
near
the
upper
right
corner

Note
For 3-Phase Wye service in the 190-264 VAC range Delta strapping must be used and no Neutral is
required. If set to Wye in this voltage range the transmitter will use Line to Neutral which will be insuf-
ficient voltage to operate the transmitter.
