14.7 Changing Between Float Charge and Equalize Charge

The procedure to change the recharge mode between float charge and equalize charge is shown in

Steps 1-3.
See the Note below for an explanation of Float and Equalize charge modes.

STEP 1

Make sure that the FLOAT CHARGE LED

is “ON”.

STEP 2

Press FLOAT/EQUAL button for at least

0.5 sec.
Change completed.
EQUAL CHARGE LED is “ON”.
FLOAT CHARGE LED is “OFF”

STEP 3

Please wait until procedure is completed.

NOTE

In equalize charge mode, the battery

is charged for a programmed period at

a specified voltage (depending on the

battery spec), rather than the float charge,

in order to prevent voltage deviations

among battery cells. This should be done

once every six months if possible.
The G8000 UPS will automatically perform

the equalize recharge after battery backup

operation.
