Reading this paragraph should be sufficient for 90% of
installers. Connect the Bat 1 and Bat 2 DC outputs to
the respective battery banks, use an appropriate fuse
(40A fuse). Then wire up the negatives (all should be
common). All DC cables should be at least AWG 10-8
(6-10 mmSq). Wire a plug to the AC Live|Earth|Neutral
cable and plug it to a 80V-270VAC (40Hz-70Hz) AC
supply. The charger should turn on and begin charging
both Bank 1 and Bank 2 at the default charging profile
of a sealed lead acid battery (14.4V abs. and 13.6V
float). This profile shall be adequate for most batteries
(please ensure). The charger does not need to be
turned off.
If users wish to install the temperature sensor for a
more accurate seasonal charging rate and for battery
temperature warnings then install onto the negative
terminal of the bank you wish to sensor (typically the
House / Service bank - as depicted).

Ensure you read the Legal and Safety before
installation. We recommend hiring a professional
to fit this charger. Above is a wiring guide.
Mount vertically in a well ventilated, dry
environment.
1) Connect DC cable to the negative (black) and
the positive Bat 1 / Bat 2 output (red).
2) Then connect the negative to the common
negative of the DC system.
3) Then connect the positive outputs via the
relevant fuse to the battery banks.
4) (Temp sensor optional) connect the exposed
wire end of the temperature sensor to the Batt
Temp Sen. port on the circuit board (as depicted
by the grey wire). Connect the yellow sensor to
the negative terminal of the battery you wish to
sense (typically the domestic / house bank).
5) Connect remote (optional) to the remote port.
6) Finally, connect the AC lead cable to NON-live
mains / circuit breaker. Ensure 80V-270VAC (40-
70Hz). Shall also run from 130VDC - 320VDC.
7) When AC is live, charger should turn on.
Ground / bonding / earthing points:
1) The earth wire (AC input, the ground).
2) The chassis / bonding ground (going to a vehicle
body / boats bonding system).
3) The DC negative.
In most installations all these will end up at the same
point. The AC power source should be connect to the
boat/vehicle chassis (for safety). The chassis earth will
also go there and the DC negative should also go
there. In effect, bonding the total system together
ensuring any fault to the chassis will blow a fuse. This
could vary for steel/aluminium boats.

This will reduce the units power by about 50% and reduce
noise. Hold A button only for 5-9 seconds. To confirm, the
half power LED shall flash 5 times. 1/2 power remains
indefinitely. To return to full power, press the setup button
again, for 5-9 seconds.
Force to Float modes
Float - mode 1.
Hold both buttons down for 2-10 seconds and let go. This
shall put the charger into float. The charger shall now
remain in float UNTIL the charger is restarted (off and on).
The charger shall then revert back bulk/abs.
Float - mode 2.
Hold both buttons down for 20-30 seconds and let go. This
shall lock the charger into float, indefinitely. If the charger is
restarted the charger shall go into float mode and remain
there.
To get out of these modes, repeat the procedures.
Energy saving mode 2 (not Lithium)
Energy saving modes
What is Energy Saving?
Energy Saving puts the charger’s DC output to that of
a charged battery:
ŸGel I, Gel II, AGM I and AGM II = 12.8V.
ŸSealed lead acid and open lead acid = 12.6V.
ŸCalcium = 12.7V.
ŸLiFePO4 = 13.4V.
The charger shall not go above this voltage and shall
be a power supply if the voltage drops below. This is
an attempt to make sure the batteries are kept
topped up, yet, preserves AC power. Allows for
utilization of renewable energy charging, like solar or
wind and takes the burden off the charger.
Mode 1
Hold A button down for 10-19 seconds. The charger
will enter ‘Energy Saving’ mode for the duration of the
charger being turned on. Once the charger is turned
off and on again the charger reverts back to
bulk/absorption voltages.
Mode 2
Hold A button down for 20-29 seconds. The charger
will enter ‘Energy Saving’ mode indefinitely. If the
charger is turned off and on again the charger
remains at 12.8V.
Force to Night Mode
This will reduce the unit’s power by around 50% for about 8
hours and reduce fan noise. Hold B only for 5-9 seconds.
The Night Mode LED shall come on solid. Please note that
night mode has to be set every single time you wish to use it.
It can NOT be set to come on at a certain time daily. Repeat
procedure

If battery temperature sensor is connected then all
voltages are based on 20DegC. If sensor senses less
than 20DegC = increased voltage. Higher than 20DegC
= decrease voltage. The further from 20DegC in either
direction leads to proportional increase or decrease in
the voltage (x2 for 24V | x3 for 36V | x4 for 48V).
Remember it is the voltages that are more important
than our battery types. After installation, test the voltage
from the unit is the desired voltage. Ensure you
remove at least 1 wire from the battery temperature
sensor as the product voltage may be higher ( if in
cold climate ) or lower ( if in warm climate ) than the
preconceived voltage. The voltage requirements of
the battery company will override our recommendations
as it is them who are supporting the battery warranty.
*Lithium profile has reverse polarity protection
disabled. **All voltages shall be 0.1V higher for
the first 3 minutes of the chargers operation.
Adjusting Battery Chemistry
Changing charging profile during startup.
While the unit is running, simply hold down the A and B
buttons for 10-20 seconds and let go. All LEDs on the
column shall now flash. The Sealed LED (yellow) shall
come on solid. Press the B button to go up the column
and the A button takes you down the column. The LED
shall light up demonstrating which profile you have
selected. When the LED has illuminated at your
desired profile simply hold both buttons for a couple of
seconds or simply just leave the charger alone for 30
seconds and it will change. The chosen profile LED
shall then flash. The unit shall then restart and go

Setting Boost/Cond./Float voltages.
Set voltages by using this column of LEDs.
The respective LED(s) shall illuminate to
denote the voltage you have chosen. If you
want a voltage in between then both LEDs,
either side, shall illuminate. To select 14.2V,
for example, both the 14.0V LED and 14.4V
LED shall come on solid. If you want 14.1V,
then the 14.0V LED shall come on solid and
the 14.4V LED shall flash.
Setting Absorption Time Factor (ATF).
ATF is simply a number (0-14) that can be used
to multiply by the length of time the charger
takes to reach the bulk/boost voltage from
start. For example, if the bulk voltage is
reached in 10 minutes with the ATF at 4, then
10mins x (ATF 4) = 40 mins of absorption. Like
above, if you need a number in between both
LEDs, either side shall illuminate solid.
Setting Min/Max absorptions times (mins)
Use this column of LEDs to pick the minimum
and maximum absorption times. There is no in
between selections, simply what is ascribed. If
there is a contradiction with the absorption
time factor (ATF) then the ATF value takes
precedence. If ATF is set to 0 and you have set
a minimum absorption time of 30 mins - 0 mins
shall be the absorption time.
Operating procedure
Press and hold both A and B buttons for 10-20
seconds.
Press the A or B buttons to move LED down to
custom (Yellow LED). Hold both buttons for 2
seconds to confirm. Now refer to the column of text to
the right hand side --->
The bottom column of LEDs have multiple functions in

BMS
Use BMS 2 - if your BMS trips to a +ve voltage (2V-17V), then use
BMS 2. This shall result in the PCUL turning off when this voltage is
received. Once the BMS removes this trip status, i.e. the +ve signal
goes back to 0V signal, the PCUL shall start charging again. The
time delay is 30 seconds.
BMS 1
status:
operational: 2-17V
trip voltage: 0V
BMS 2
status:
operational: 0V
trip voltage: 2V-17V
or
Use BMS 1 - if your BMS trips and provides a 0V (ground signal), then
use BMS 1. This shall result in the BBC turning off. Once the BMS
removes this trip status, i.e. the 0V signal goes back to a +ve signal,
the PCUL shall start charging again. The time delay is 30 seconds.
Remote trip - the BMS connector can also be used as a basic remote trip. Simply apply the
correct trip signal voltage to the relevant BMS connector for the desired effect.
Connect the temperature sensor
(TSAY) to the negative terminal of
the battery bank. It is imperative
that the sensor is put on the
negative terminal.
The temp sensor has two
cables at the end. Place one
in each of the two connectors.
The polarity does not matter.
The Daisy chain link should
come with a bridging link, as
depicted. If you have no use
for this feature, leave this link
in place.
If this link is removed, the
charger shall stop. Reconnect
the link and turn off charger at
the mains and turn on again to
resume charging.

8) BMS 1 and 2 port - ensure you do not have connections to both ports. Only use one port or no ports. BMS1 must
be connected to a signal that goes to ground (0V) under trip conditions. BMS2 must be connected to a signal with a
positive voltage (2-19V) under trip conditions.
9) Negative DC - ensure your negatives are common throughout your DC circuitry.
10) Secondary high voltage trip, critical fault. Worth calling Sterling Power.
19) Power reduce. % (fl) - table:
The charger’s power output
reduces based on internal
temperature. If your charger
is not putting out full power
then refer to this table.
20) Solid - High unit temp. trip. The charger’s temperature has reached 96DegC+. The ambient temperature is too
high for the PCUL to operate. Turn off at mains, move to cooler environment, turn on.
High Batt. Temp (fl). This LED shall only be flashing if you have the temp sensor connected to port 2. If your battery’s
temperature has exceed 55DegC then this LED shall flash.
22) Solid LED - daisy chain trip LED - check the daisy chain link connector - you either have a trip signal from your
daisy chain or the link connector has fallen out.
1 x Flash LED - High Voltage trip - The DC voltage across the battery has exceeded 16V. You may have solar power
- it is worth getting a solar regulator to bring this voltage down.
2 x Flash LED - BMS trip - if you have a BMS trip cable going to the BMS connector the signal has tripped the
charger. Wait for the BMS trip signal to go. BMS connector can also be use as a signal trip to an on/off style switch,
ensure this switch is in the correct position.

one of connector and the other wire into the
remaining connect. Polarity does not matter.
3) Daisy chain link - ensure there is a bridge
between these two slots. If there is no bridge
connector, the PCUL shall not charge. If you
have reconnected the bridge connection -
you will need to turn off charger + on again.
4) Positive DC battery outputs 1 & 2 - ensure
you have battery voltage at both of these
terminals. If you have 0V then your batteries
are either not connected or you have
continuity issues between PCUL and battery.
If you are using on one output, please link the
other output up to it.
6) Fuse - 40A fuse. If blown, please replace.
Ensure good contact between fuse and fuse
holder.
The primary test the user can do before calling Sterling is to check
what your AC input voltage is going into the PCUL. Ensure it is
between 80-270VAC. Do the LEDs on the PCUL display then come
on? If they do, then measure the DC voltage across the negative and
positive terminals of the PCUL. If you are getting battery voltage (10-
12V) then check the PCUL has not been turned off or put into energy
saving mode (check page 6). If you are getting 0V here, please
check you have got continuity between the batteries and the
charger. Possible fuse blown, possible poor contact, loose cable etc.
