5.1
Safety interlock Operation
i
i
WARNING!
Use the safety interlock function within danger areas.
Any area where personnel may come into direct contact with high power RF, or
be exposed to non-ionising radiation, should be designated as a danger area.
A barrier should be established around this area, with a switch opening when
the barrier is broken. This should be linked to the safety interlock connector,
disabling the amplifier when the barrier is breached. (It is the responsibility of
the operator to ensure a safe working environment).
Safety interlock connections are via a BNC connector on the rear panel. This should
be used with an appropriate switching or control arrangement so that the amplifier is
disabled when any barrier to a dangerous area is broken. Once the interlock
connection is broken the amplifier will default to standby mode. Once the interlock
connection is remade the amplifier will automatically resume operation in “

5.2
Switching on line supply
After ensuring that the amplifier front panel rocker switch is in the down position (off)
ensure the mains lead is connected to the correct AC line source. Depending on the
model of CBA,
1
Switch the rear panel 3 phase circuit breaker to the
“
On
”
position. The rear
panel circuit breaker provides AC overcurrent protection. There will be no
amplifier indication as a result of this step.
2
Switch the front panel rocker switch to the Up (On) position. The touchscreen
will indicate that the boot up process has begun.

Hints and tips:
This switch can remain in the ON position all the time, but it is best
set to OFF when the amplifier is not being used for long periods.
