Defibrillator Capacitor
WAR NI NG Always discharge the defibrillator capacitor before performing any service opera-
tions on this unit. See "Separate the Case" on page 4-26.
Preparation
1. Save the configuration.
If possible, save the customer’s configuration onto a Data Card (or print
the configuration) so the configuration can be restored after repair.
2. Open the case safely.
See "Opening the Case" on page 4-24.
Removal
1. Lift the capacitor out of the way.
Lift up the defibrillator capacitor and its foam base. Lift straight up, then
turn and rest them on the Power PCA. See Figure 4-41 on page 4-85.
2. Disconnect the capacitor.
a. Before disconnecting the capacitor, note the polarity and routing of its
two wires: the red wire to the spade connector next to the red induc-
tor, and the white wire to the spade up in the corner of the Power
PCA.
b. Unplug the defibrillator capacitor from the Power PCA by pulling
straight up on its spade connectors with needle nose pliers. Take care
to not stress the wires.
3. Remove the capacitor.
a. Slide the wires out through the hole in the foam base.
b. Using a clip lead, short the capacitor’s terminals together to prevent
charge accumulation and lay the defibrillator capacitor aside.
Replacement
1. Replace the capacitor.
a. The new capacitor will come with a shorting bar connecting the two
terminals. Disconnect the shorting bar.
b. Slide the wires through the large hole in the foam base.
2. Connect the capacitor.
Plug the terminals onto the spade connectors on the Power PCA. Orient
the wires so they point toward the center of the Power PCA, as shown in
Figure 4-41.
NOTE The correct polarity is with the red wire near the red inductor and the white
wire near the back corner of the Power PCA.
