Electrical Hazards

Most of the electronics require DC voltage for inputs. These DC voltages are provided by the power supplies of the crates in which the modules sit. There are several powered NIM crates, each with a power supply that requires 115 VAC input and provides approximately 200 Watts of power on +/- 6, 12, and 24 VDC output lines. There are some CAMAC crates which also require 115 VAC input, and provide a maximum of 400-500 Watts. There are also a number of VME crates, whose power supplies provide approximately 500 W. These all run off of clean power, which is provided from power strips installed in the racks, and use standard power cords. There are also 2 Fastbus crates which require 208 VAC input, and can provide a maximum power output of roughly 4000 W. They have exposed power connection in the back of the fastbus crate. The racks in which they are mounted have rear doors that will be closed at all times when the fastbus power supply is on. There will be shields installed over the back of the fastbus power supply to prevent conta ct with the power leads.
