To install the ac charging unit:
Remove one of the plugs from the side of the flow computer so that the ac charging unit can be mounted without
obstruction (see Figure 58).
Feed the ac charger dc power lines into the flow computer. Allow enough cable to extend into the unit for connection
to the EXT CHGR +/- terminals.
Connect the ac charger unit to the flow computer using the supplied sealing ring and nut (see Figure 59).
CAUTION – Equipment / Property damage: To prevent moisture from entering the flow computer enclosure after
!
installing the AC battery pack charger unit, be certain that the associated connector at the charger unit has a metal
backed sealing "O" ring and metal locking nut attached.
Trim the wire ends back 1/4", before connecting the charger wiring.
Remove the associated EXT CHGR terminal block J5 (see Figure 53) from the flow computer board.
Loosen the terminal block securing screws.
Insert the red wire into the plus (+) terminal (top) and the black wire into the negative (-) terminal (bottom).
Retighten the screws, and reinstall the terminal block with the wires attached.
Plumb the conduit and associated ac wiring into the ac charger conduit box. The ac charger is rated at either 120 Vac
60 Hz or 240 Vac 50 Hz.
Connect the 120 Vac hot and neutral or the two hot wires for 240 V to TB1 of the ac charger.
Connect the ground wire to the green screw T1 (see Figure 60).
Verify that the DC power wires are terminated properly inside the flow computer cabinet.
Verify that the main battery pack is plugged into J1 (see Figure 53).
Apply ac power to the ac charger.
Monitor dc charging voltage by observing the flow computer display. LCD should indicate CHARGER 13.0 - 13.5 Vdc.
The ac charging unit is now installed.
