Description

The Model 2290-5 and 2290-10 can contain hazardous voltages. Be certain that the high
voltage is completely discharged before removing or connecting the high-voltage cable.
High-voltage cables can store charge if they are disconnected from the supply while high
voltage is turned on and can cause personal injury or death if not handled properly.
Do not connect the HIGH-VOLTAGE output to exposed circuitry. Any load connected to the
HIGH-VOLTAGE output should be enclosed in a metal shield that is connected to safety earth
ground using #18AWG or larger wire.
The Model 2290-INT-CABLE connects the safety interlock on the Model 2290-5 or 2290-10 to your interlocked
test fixture.

High-voltage installation:

1. Turn off power and allow all voltage to discharge.
2. Install the Model-INT-CABLE safety interlock on the Model 2290-5 or 2290-10 to your interlocked test
fixture (see next figure).
