4 FUSE INSTALLATION
The VoltPAQ-X2 has two 3.0A fuses and the VoltPAQ-X4 has four 3.0A fuses. The fuses protect the amplifier from
over-current through the main power connector. The recommended fuse for this unit is the Cooper Bussmann MDL-
3-R, which is rated for 3A and 250V.
Caution: Make sure the power to the amplifier is disconnected before changing any fuses!
Follow this procedure to install or replace the fuses in the VoltPAQ-X2 and -X4:
1. The fuse holders are located at the rear of the unit, as shown in Figure 2.1.
2. Make sure the amplifier power cable is disconnected.
3. Remove the fuse holder. There are three fuses in the VoltPAQ-X2 and five in the VoltPAQ-X4. To do this, push
and twist the knob counter-clockwise and pull the fuse holder out as illustrated in Figure 4.1.
4. As shown in Figure 4.2, remove the old fuses from the holders and insert the new ones.
5. Install the fuse holders back into the amplifier. Make sure the fuse being installed corresponds to the label at
the back of the amplifier, i.e., 3.0A (labels shown in Figure 4.1). Push the fuse holder back into panel and twist
the knob clockwise until secure.
Caution: Installing the wrong fuse rating may result in damage to your amplifier.
