One side of the high voltage transformer output is connected to the earth system of the
equipment.
1.1.3 Zero Voltage Interlock
The equipment is fitted with a zero volt interlock system on the output control. This interlock
prevents the output being energised unless the output control is in the minimum output
position.
1.1.4 External Interlock
The equipment is fitted with a external interlock system. The interlock socket on the back
panel must have a short circuit across it terminals to enable the output to be energised.
Note: the open circuit voltage across the interlock terminals is 240Vac and is connected
directly to the mains supply.
