Installation

Mounting Connectors

Installing the interlock circuit

Install the interlock circuit as follows:

1. Mount two mechanical switches on your shielding box, so that the switches

close when the door of the shielding box is closed, and open when the door is

opened. For the dimensions of the switch, see

Figure 3-13 and Figure 3-14

below.

2. Mount an LED on your shielding box. For the dimensions of the LED, see

Figure 3-12.

3. Use wire to connect the two switches in series between pin number 1 and 2 (or

3) of the interlock connector. See

Figure 3-11.

4. Use wire to connect the LED between pin number 4 and 5 (or 6) of the interlock

connector. See

Figure 3-11.

If Agilent B1500A Interlock connector is connected to the interlock circuit, Agilent

B1500A SMU cannot force more than ± 42 V when the door is open. When the door

is closed, it can force more than ± 42 V.

When more than ± 42 V is forced from an SMU, the LED lights to indicate high

voltage output.
