Electrical wiring considerations

Install 2 A slow-blow fuses (customer supplied) in the voltage measurement input circuits as shown in the electrical wiring diagrams. The auxiliary power supply circuit, if applicable, must also be fused. See “Step 4: Connect the optional auxiliary power” for details.

NOTE: Built-in shorting blocks are provided within the FT-21 drawout case so when the meter is removed, the shorting blocks automatically short-circuit the current inputs.
