June 2003 IPN: M5000-00-105 Multi-charger E - 15Multi-chargerThe multi-charger (TOPA-CH-300) is made upof six desktop fast chargers that operateindependently of one another. Each multi-charger PCB has an additional diode.Multi-charger operationThe operation of the multi-charger is the sameas that of the desktop fast charger.Figure E-7: The Tait Orca six-way multi-chargerRepairing the multi-chargerShould one of the charger units be faulty, youcan repair it according to the instructions forthe desktop fast charger, or replace the faultyPCB with a fast charger PCB to which the diode(1N4001 or similar) has been added (refer toFigure E-8).To remove a faulty charger from the multi-charger: Unplug the power cord. Undo the 10 screws at the base of the radiousing a Pozi 1 driver. Do notDo notDo notDo not pull the top off the charger usingthe housing of the individual chargers.Instead, from the side of the charger, liftthe top cover up and gently fold back. Unplug the red and black wires leading tothe faulty charger. Remove the three screws holding thefaulty charger to the top of the multi-charger. Gently pull the faulty charger away fromthe multi-charger top. Turn the chargerupside down so that the release tab is atthe top. Depress the release tab using the end of aflat-bladed screwdriver and gently pull thebase away from the body. Desolder both wires. Repair the board or replace it with a newone to which the required diode has beenadded. Pass the wires through the charger base. Solder the red wire to the positive terminalon the PCB and the black wire to thenegative terminal on the PCB. Place the charger upside down and makesure the conditioning button, the lightpipe and the PCB are seated properly. Attach the base at the front edge, and clipit down at the back.
