General precautions  
SHOCK HAZARD! Do not open the case  
of this product. There are dangerous  
voltages present within the unit. There are  
no user-serviceable parts within the unit.  
Before installing and using your new  
capacitor, please become fa-  
miliar with all the information con-  
tained in this manual.  
WARNING! This power capacitor may  
explode and cause serious injury or  
death if abused or connected  
improperly.  
Please keep this manual in a safe  
place for future reference.  
• Do not open or attempt to repair this  
unit yourself. Dangerous high voltages  
are present which may result in electric  
shock. Refer any repairs to a qualified  
service technician.  
Refer to this installation manual for correct  
procedures when making connections,  
and for charging and discharging the  
capacitor. Never expose the capacitor to  
voltages higher than specified!  
To avoid risk of electronic shock or  
damage to the unit, do not permit any  
of this equipment to become damp or  
wet from water or drinks. If this does  
occur, immediately unplug the power  
wires and send the product to your  
local dealer or service center as soon  
as possible.  
• If there is smoke or any peculiar odor  
present during use or if there is damage  
to any of the component enclosures,  
immediately unplug the power cord  
and send the product to your local  
dealer or service center as soon as  
possible .

Installation precautions  
Prior to installing and connecting the capacitor, please study the drawing  
below and become familiar with the physical features of the capacitor.  
Securely mount the capacitor using the hardware provided. Be careful when  
choosing a mounting location to avoid moving parts, and possible exposure to  
moisture.

Important note about charging the capacitor  
This capacitor must be charged BEFORE connecting the POWER and GROUND  
cable to the capacitor.  
Failure to charge the capacitor will result in a large spark generated form the rapid  
inflow of current which can be very dangerous.  
Electrical connections for CAP18 or CAP30  
Make all wiring connections as shown in the diagram, but do not attach the  
incoming positive cable to the capacitor positive terminal.  
Connect the positive terminal only after following the instructions for charging the  
capacitor on page 8.

Charging the capacitor  
As noted earlier, make all connections according to the diagram(s) on the preceding  
pages EXCEPT for the POSITIVE (+) connection to the capacitor. To charge the  
capacitor, follow these steps:  
1) Pick up the cable coming from the POSITIVE (+) battery terminal.  
2) Place the supplied charging resistor between the end of this cable and the  
positive terminal of the capacitor. The capacitor will begin charging. Charging  
generally takes 5-60 seconds. During charging, the voltage shown in the 3-digit  
display will rise rapidly, then slow as it approaches the voltage of your vehicle’s  
battery. When fully charged, the displayed voltage will stop rising.  
If you have a voltmeter, you can first measure the voltage of your car battery. Then  
you will know with accuracy that the capacitor is fully charged.  
CAUTION!! During charging, the resistor will become hot. This is normal, but exercise  
caution during the charging process.  
3) After charging is complete, remove the resistor from the incoming positive cable,  
and IMMEDIATELY connect it to the positive terminal of the capacitor.  
The installation and charging process are now complete, and you can begin using  
your audio system and enjoying the benefits of your new system enhancement.

Discharging the capacitor  
CAUTION!!  
Never remove the capacitor without discharging the stored power. It can give a dangerous  
electrical shock, even after disconnection.  
To safely discharge and disconnect the capacitor, follow these steps:  
1) Disconnect cables from the capacitor in the following order:  
POSITIVE cable  
GROUND cable  
REMOTE cable  
2) Using the resistor provided, touch one lead to the POSITIVE (+) terminal and one  
lead to the NEGATIVE (-) terminal.  
CAUTION!! During discharging, the resistor will become hot. This is normal, but  
exercise caution during the discharging process.  
After 1-5 minutes, the capacitor will be discharged ( the display will show 0.00V)  
and you can safely remove and handle it.
