20.3. Power Supply Safety and Thermal Management
20.3.1. High Voltage
The voltages inside the Cypher SPM are as dangerous as those present in a standard wall socket; there-
fore, you should respect all of the components under the instrument covers as you would a wall socket.
Never touch anything or insert anything conductive under the instrument covers. Also, the piezoelectric
actuators in the scanner have a large capacitance and can hold charge for many minutes after the scanner
is disconnected from any power supply. For this reason never touch the scanner connector, unless it has
been unplugged for at least 10 minutes.
Warning
The Cypher SPM and ARC2 controller contain internal voltages up to 165VDC,
0.5A. Use caution when handling system pieces to avoid electrical injury. These
voltages may be lethal.
