3x3 UPS
Issue 2 - November 2001
When fitting a replacement PCB the on board links must be checked to ensure they are in
the correct position.
a) JPI JP2 sets the recharging current.
Link/Ampere
b) JP3 enable/disables the boost charge.
c) JP4 enable/disables the temperature compensation circuit.
d) Jumpers JP5 to JPI0 set the capacity for the installed battery, this is used for the battery
test function.
Link
e) JP11 when selected open inhibits the battery test regime.
f) J4 J5 J6 set the automatic battery test interval
It is unlikely that any potentiometer adjustment will be required on a replacement PCB
however the function is listed below.
a) P1 = adjusts the float voltage level to 432 Vdc
b) P2 = adjusts the boost voltage level. This setting is dependant on the type of battery
fitted.
c) P3 = adjusts the float voltage when the temperature compensation option is enabled.
Refit all covers removed and return the UPS to its normal operating condition.
