System Emergency Off (E-Off) Switch

The E-Off switch removes all power to a CT system immediately. If for any reason the operator
needs to remove all power supplied to the CT system at the main distribution panel, the E-Off
switches should be employed. Using this switch except in the case of an emergency could cause
damage to hardware. Typically, one or more E-Off switches are located in or near the operator
console or gantry. Know their locations.
