Request part number 873‐3716‐0, CFB Equalize 2 pin assembly. Proceed with the installation as follows:
(Caution: Ensure AC input has been disconnected before proceeding)
1) Remove the two phillips head screws on the front panel (bottom right and just above the output
terminals), as well as the two phillips head screws on each side of the unit.
2) Carefully lift the main cover off of the charger base. It is not necessary to remove the drip shield.
3) Locate the two‐pin header labeled "J2" just over the cut‐out on the bottom of the front‐facing charger
function circuit board. Insert the mating connector and route the two control wires through the vent
hole on the bottom of the charger. Connect the wires to the timer.
4) Replace the charger cover. When lowering the cover onto the base , avoid damaging connectors on
the charger/function PCB. If used, re‐install the drip shield.
G) Output Ammeter
This will indicate total charging output current for all battery banks connected.
H) Power‐On Indicator
This green LED will glow whenever the charger is receiving AC power.

A) Start Up
1) Before powering up your charger, check for tight electrical connections to each battery in your
system. Switch off any DC loads on the batteries. Apply AC power. Observe the DC ammeter on the front
panel. This meter displays the total DC output of the charger, through all banks. It will give some
indication of the overall state of charge of your batteries. If the meter is reading mid‐scale or higher, it is
an indication that the batteries are in a relatively low state of charge. The charger, sensing this, is
supplying high current to the batteries. If the meter needle is at or near the bottom of the scale the
batteries are at or nearing full charge.
2) Apply a load to the charger by switching on some lights, a pump or some other DC appliance. Observe
the charger meter. It should read approximately the same as the expected current draw of the
appliance. As current is demanded from the battery system, the charger will automatically increase its
output in response to the increased load demand. When load current exceeds 10‐20 % of the charger's
rated capacity, the charger will go into the absorption mode and remain there until current drops below
5‐15 % of capacity or until the time‐out circuit cycle is complete.
B) Constant Versus Occasional Use
In general, it is recommended that the charger be left connected continuously to the AC distribution
system so that it will be in operation whenever AC is available. This will maintain batteries at peak
voltage and will automatically compensate for the natural self‐discharge of the battery system. When a
load is applied to the battery system the charger's output will automatically increase to supply the
current which would otherwise draw battery voltage down. Repeatedly allowing batteries to become
completely discharged before recharging will greatly shorten their life. Leaving the charger on
continuously will prevent this.
