Fig. 6.5 Connecting the voltage supply
The voltage supply leads can be routed together with the
interface leads in one cable, or you can use a separate
cable. If several AEDs are being supplied by one cable,
note the voltage drop over the cable, so that the supply
voltage to the AEDs does not get too low. The voltage
