The charger is pre-set to operate from input AC voltage of 120 VAC, 60 Hz. To operate
the charger from AC input voltage of 230 VAC, 50 Hz, change the internal setting as
follows:
1. Remove the side plate that has the power cord entry by unscrewing 4 screws
2. Remove the Voltmeter and the Ammeter on the top central plate by prying up the
bottom edges of the meters with a broad, flat screw driver and by pushing the meters
up from the bottom of the plate (these are snap fitted). Remove the connecting wires
and mark them. Note the polarity for connecting back in proper polarity. The meter
terminals are marked Positive (+) and Negative (-). Thicker wires are for the Ammeter
and thinner are for the Voltmeter
3. Gently slide the center top cover plate out. Note and mark its orientation for
correct re-fitting
4. Locate Yellow loop of jumper wire with quick female disconnect. In the pre-set
120 VAC condition, this jumper wire is shorting the male vertical pins marked "C" and
"D" and "115V". Pull any one end of this female disconnect upwards to disconnect
shorting between "C" and "D". Insulate this end with insulating tape. The unit is now
set for "230 VAC"
5. The 120 VAC version has a soldered 12A fuse on the AC side. When converting
120 VAC version unit for 230 VAC operation, there is no need to replace the 12A fuse
6. Replace the AC plug of the power cord with a suitable 3 pin grounded plug to mate
with the 230 VAC outlet.

cAUtion!
The new plug should have 3 poles i.e. Line (L), Neutral (N) and Earth ground.
Color code for the power cord conductors is:
- Line (L) - Black
- Neutral (N) - White
- Earth ground - Green

As shown in Fig. 7.1 and 7.2 (page 19), the output of the charger has a common Nega-
tive (-) connector and 2 Positive connectors for connection of 2 banks of batteries. Each
Positive connector has its own internal isolating diode, which works as a battery isolator.
If more than one bank of batteries is connected, these will be charged at the same time
as long as the AC power is available to the charger (the maximum charging current of
50A of SEC-1250UL and 25A of SEC-2425UL will be shared among the connected banks
of the batteries depending upon their discharged states). In case the AC power fails
or if there is no output from the charger, the isolating diodes will prevent charging /
discharging among the batteries connected to the banks.
