DC Input and Grounding Cable:
• All DC cables require insulated multi-strand low resistance cable.
• The DC cables must be copper and must be rated 105º minimum
Model Minimum Wire Size Recommended cable size between DC source and inverter
2000W Unit 70mm2< 1.5m
2600W Unit 120mm2<1.5m
CAUTION
Use of smaller gauge cable or longer cable length may cause the inverter to shutdown under heavy
load and may also melt the cable insulation and catch re. This could result in death or serious
injury. Choose of the cable size should also match with the rating of the DC fuse used.
Important:
The recommended cable length is limited to < 1.5m. This is due to the consideration of voltage
drop between the battery and the unit. Change to use a bigger size cable is needed if long cable
length is used.
ePOWER Inverter Chassis Grounding Connection:
DANGER!
The ePOWER Inverter chassis is to be grounded properly. Never operate the ePOWER Inverter
without proper grounding. Failure to do so will result in death or serious injury.
1. Connect the grounding cable’s ring terminal to the unit ground screw.
2. Connect the other side of the cable to the common grounding point.
Grounding Cable Size:
Important: The unit is grounded through the ground stud located near the DC Input terminal and the
chassis of the unit has to be grounded properly before use.
• The unit has to be grounded with a minimum 10mm2 copper conductor.
ePOWER Inverter DC Input Connection:
CAUTION
Reversing the DC Input terminal will damage the unit and cannot be repaired. Damage caused by
reverse polarity connection is not covered by the warranty.

Enerdrive ePOWER Inverter Owners Manual (Rev. 1.0)Page 10
1. Connect one end of the negative DC input cable to the ePOWER Inverter DC negative terminal.
Connect the other end of the negative DC input cable to the battery negative or System side of
the Shunt if a battery monitor is installed.
2. Make sure the disconnect switch (battery switch), if tted, is in the OFF position.
3. Connect one end of the positive DC input cable to the ePOWER Inverter DC positive terminal.
Connect the other end of the positive DC input cable to one of the terminal of the Disconnect Switch.
4. Connect a DC input cable between the other terminal of the Disconnect Switch and one side of
the terminal of the fuse holder.
5. Connect a DC input cable between the other terminal of the fuse holder and the battery positive
terminal.
6. Install the selected fuse to the fuse holder.
7. Turn disconnect switch (battery switch), if tted, to the ON position.
AC Output Connections:
CAUTION
Please be sure that the AC Input source is not energized before making any Output connection
and that the DC disconnect switch is turned OFF.
Automatic AC Transfer Switch
This inverter is tted with an Automatic AC Transfer switch. This transfer switch seamlessly diverts AC
power from mains/generator supply and/or the inverter supply through the 16A IEC Output socket
that’s mounted on the side of the inverter. There are two IEC sockets, 1 x AC Inlet & 1 x AC Outlet that are
required to be hardwired to your on-board electrical system if you wish to use the transfer switch option.
When mains/generator power is applied to the AC Input IEC socket, the Auto Transfer Switch switches
this power through to the 16A IEC Output socket as well as the 10A 3pin GPO outlet mounted on the
front of the inverter.
When the inverter is operating as an “Inverter” both the IEC Output socket and 3pin GPO are supplied
from the battery to a maximum wattage output of the inverter.
When the inverter is operating with mains/generator power input, the maximum transfer wattage is
3500W (16A AC) for the IEC Output socket or 2400W (10A AC) for the 3pin GPO outlet.
To use the 16A IEC sockets, the unit is supplied with a separate male & female IEC plug as standard. These
plugs are designed to be hardwired by a qualied electrician to the AC distribution of the intended
installation.
AC Input Source and AC Branch Breaker:
• Standard AC Input wire is required for all the AC connections between the AC source & the AC Input
port, and the AC Output ports to load.
• For 230V model and maximum By-Pass power rating, a minimum of 2.5mm2 AC wire is required. A 16A
branch circuit breaker is also required to connect between AC Input source and unit’s AC Input port.
Important: Follow the local electrical and/or building code when you connect the unit to any AC source.

www.enerdrive.com.au Page 11
Residual Current Device (RCD Safety Switch)
This inverter is tted with a Residual Current Device (RCD Safety switch as standard). The Residual
Current Device (RCD) switch detects if there is an earth leakage fault and will automatically disconnect
all output power sockets protecting the user from electrocution. Meets Australian Standards for AS4763
(portable inverters) and AS3001 (caravan installation)
The inverter has a Mains Earth Neutral (M.E.N) connection permanently installed on the inverter side
of the AC Transfer switch. This allows the RCD to work correctly while on Inverter.
This system of earthing provides a reference between the Ground/Earth and the Neutral circuit allowing
for detection of imbalance between the Active and Neutral Circuits in the event of a fault.
With no MEN connection in place, protective devices will not operate correctly to ensure the installation
is electrically safe.
When the Transfer switch is active and allowing AC power from the IEC Input socket to pass through
to the Outlet circuits, the RCD needs to rely on the M.E.N connection of the Input Power supplied for
maximum protection.
Please note: The majority of generators on the market do not have an M.E.N connection. If no M.E.N
is present on the IEC Input socket, the RCD will not supply the maximum protection while the Transfer
Switch is active.
Remote Control / Display Connection
• The Remote Display on the unit is detachable. To install the remote in a dierent location, the provided
6 pin standard RJ12 “rollover” cable is used.
• Remove the 2 screws at the front of the Display Panel and disconnect the small RJ12 cable from the unit.
• Install the RJ12 cable in your desired location and connect the RJ12 cable to the unit and the other
end of the cable to the Display Panel. Please note polarity. Refer Appendix II
Test the ePOWER Inverter connection:
1. Switch the AC Branch Breaker to ON to provide AC Input power to the unit.
2. The LED on display will turn on. If AC input source is available, ‘Status’ LED turns green. This indicates
the unit is running in By-Pass mode meaning AC output is running from the AC input source.
3. Disconnecting the AC input source by turning OFF the AC Input to the inverter. The ‘Status’ LED
on the display will switch to amber.
4. Both AC outputs and 5V USB are now available and the unit is running on battery power.
5. Plug a small AC load into the front power point, like a 40W table lamp or small appliance to the
front AC socket to verify AC is available.
6. The unit is successfully installed and functioning properly.

“E01” or “E05” alarm
in By-Pass (pass-
through) mode 2
The unit is normal.
The alarms indicate the battery voltage is low or
the battery is not connected.
Note: There may be external DC loads connect
to the DC input terminals and its drawing current
from the current-limited built-in trickle battery
charger within the inverter. However the unit
continues supplying AC-Output power in despite
of those alarms
Charge and/or connect the battery bank or
disable all the audible alarms with the “AL0”
setting when AC backup is not required.
Note: The main purpose of the internal trickle
battery charger is to keep the unit’s control
electronics working and can still provide AC
Out when utility is available even without the
battery connected. It is not intended to act as
a real trickle charger for your battery bank.
Therefore do not rely on this small trickle charger
as a source to charge your battery bank.
DC voltage is
measured at the DC
terminals without
the battery being
connected (EN1120x,
EN1126X only)
This is normal.
The voltage is supplied by a little built-in trickle
battery charger with current limiting protection.
You can keep the battery disconnected.
However if the DC-Input terminals of the unit
are connected to a common DC bus being shared
by other DC loads, a 12V back feed to those DC
loads can occur when the DC bus is disconnected
from the common battery bank. In this case the
corresponding drawing current may trigger the
“E01” or “E05” alarms as per the problem 2
In cases where the back feed is not desirable,
consider using a separate battery bank
disconnect switch for the unit
The unit’s 10A
thermal breaker trips
even when the unit
is out of an overload
condition
This happens mainly in By-Pass mode when
the maximum rating of the unit’s breaker is
exceeded.
For maximum capacity use the 16A AC-Output
socket which is out of the tripping inuence of
the unit’s 10A thermal breaker. Otherwise do not
exceed 10A on the front AC outlet respectively.
The unit cannot be
turned o using the
power button when in
“By-Pass” mode
This is normal. The unit has “PS1’ (factory
default) setting. Use the procedure on the right
to turn o the unit.
Note: The power button On/O action takes
place at its release moment and after a “beep”
is heard
To turn the unit o while in By-Pass (pass-
through) mode, rst of all disconnect the AC-
Input that feeds the unit to force entering into
Battery (inverter) mode. Then push and hold the
power button for 1 sec. (after hearing a beep)
the unit will turn o.
Set unit to PS4 mode. With this setting, the
power button can be used to turn the unit ON
and OFF during By-Pass and Battery (inverter)
mode.

The input battery
under-voltage
warning (“E05”) and/
or shutdown alarm
(“E01”) occurs in
advance even when
the battery voltage
seems to be OK
Make sure you are measuring the voltage
directly at the DC-Input terminals of the unit so
as to check the possible voltage drop between
the battery posts and the unit input terminals
Excessive voltage drop between the battery
bank and the inverter, due to high resistance
of the DC wires, battery disconnect switch,
fuse or DC breaker if any. Make sure to use the
recommended wire’s gauge and length. Try to
use fuses (or DC breakers) with very low voltage
drop (i.e. Class T type fuses, etc.)
Battery bank with high internal resistance,
resulting in a voltage drop proportional to the
DC current draw from the unit.
Too much battery voltage drop due to excessive
drawing current in relation to the battery bank
capacity. Increase the battery bank capacity (i.e.
adding more batteries in parallel) and/or reduce
the load being fed by the inverter
Battery damaged and not able to keep a
good state of charge. Replace the battery (or
batteries)
Battery bank is getting discharged.
This is normal condition. The E05 warning and
then followed by the E01 shutdown occur while
the battery bank is getting discharged. Charge
the battery bank.
Make sure to measure the battery voltage
just before the “E01” battery under-voltage
shutdown in battery (inverter) mode occurs
and compare it with the corresponding voltage
threshold in the specications table. (allow +/-
5% of tolerance)
Just after the E01 occurs, the battery voltage
increases rapidly since the battery is not under
load condition after the inverter shutdown.
This is normal in all battery banks and can
confuse the user thinking the under-voltage
shutdown that triggered the E02 alarm occurs in
advance at higher voltage thresholds than the
ones specied.
The E05 warning and E01 shutdown alarm occurs
well in advance due to the “SdH” setting
If you want to extend the run time of the
battery bank as long as possible without the
need to keep enough battery state of charge for
engine cranking purposes, make sure to set the
under-voltage shutdown threshold to low values
setting (“SdL” - factory default setting) rather
than the “SdH”.
