Interlock

The interlock function is designed to prevent electrical shock when a user touches
the measurement terminals. If the Interlock terminal on the rear panel is open,
Voltage Source cannot apply a high voltage over 21 V.
To remove this restriction for high voltage output, the Interlock terminal must be
connected to an interlock circuit installed in a test fixture or a connection
interface. If there is no interlock circuit, you need to install it. For more information
on the interlock circuit and how to install the interlock circuit, see
Interlock Circuit" on page
If the interlock circuit is opened during Voltage Source applies a voltage over 21
V, the output voltage is set to 0 V immediately and the output relay is opened.
