Connection conditions
1. The X-ray exposure signal line (including switching mechanism) must be insulated, and its
total impedance must be 100 ohms or less.
2. The maximum contact voltage of the X-ray exposure authorization signal line is AC 250V
and DC 30V, and its current ranges from 10mA to 2A.
Only the insulated secondary power supply can be connected.
3. The protective installation of the X-ray generator must have the same electrical potential as
the system.
