Overload and Shutdown
The amplifier is protected against short-circuit, over-current, and excessive temperature. During these
conditions, the front panel overload indicator will illuminate and the rear-panel Overload signal is +5V.
During an overload or shutdown state, the output is disabled.
When the amplifier is switched on, the overload protection circuit is engaged by default and clears after
three seconds.
The amplifier can be shut down by an external source by applying a voltage of b3V and +24V to
the Shutdown input on the rear panel. The impedance of the shutdown input is approximately 5 kΩ.

HV Output Screw Terminals
The screw terminal output has contacts for the output voltage, output return, and the internal HV supply
rails. The Output- signal is connected to ground through a 0.1 Ohm resistor.
Stack actuators are connected as shown below.
