6.2 Changing Voltages
Prior to shipment, Innova shakers are set at the appropriate line voltage with the
proper fuses. The power module, however, is a universal power-entry system that can
be reset to adapt to worldwide power requirements.
If it is necessary to reset the voltage on your shaker, use the following procedure:
1. Turn the unit off and disconnect it from the power source.
2. Open the cover of the power module, using a small blade screwdriver or the like,
and remove the cover/fuse block assembly (see Figure 6) .
3. Remove the voltage selector card from the housing by pulling the indicator pin
straight out (see Figure 6) .
4. Along each edge of the voltage selector card, the voltage options are printed in
large numbers: 100, 120, 220, 240. Place the card in front of you with the desired
voltage printed at the bottom
(see Figure 7) .
5. With the card in this position, orient the indicator pin to point up. The voltage has
now been changed and the card can be reinserted.

6. Hold the voltage selector card so that the indicator pin is facing you and the
alignment arrow points left (see Figure 8) .
7. Replace the card in the voltage selector slot at the righthand end of the power
module. Push it until it snaps into place.
8. Check for the correct fusing arrangement (see Section 6.3) .
NOTE:
Be sure the indicator pin is facing out and the alignment arrow is
pointing to the left.
9. Replace the cover/fuse block assembly.
10. Verify that the indicator pin shows the desired voltage.
