Fault Finding
No indicators ON when power is first applied
When first connected, if the LD200 shows no indicators the battery
connections may be reversed. Check that the red battery wire (6) is connected
to the battery positive, and the black battery wire (7) is connected to the
battery negative.
Inverter shuts down during the middle of the day, and comes
back ON late in the afternoon
This is more than likely caused by high battery volts during peak charging
times from Solar Panels. Battery volts should never exceed 17 volts. If this is
the case, have your Solar Regulator checked.

Portable Use
By connecting battery clips, the LD200 can be clipped directly to a vehicle
battery. When using battery clips ensure they have a tight grip around the
battery post. Wherever possible battery connections should be bolted. If
connecting the LD200 through a cigarette lighter socket the maximum
power output of the LD200 will be severely restricted, this practice should
be avoided. Check with your supplier or installer if you are unsure.
Do not use battery clips in a moving vehicle

By incorporating an auxiliary battery in the manner above, the starting battery
should remain charged for vehicle starting (see your auto electrician).
The LD200 has sufficient battery cable length to allow it to sit underneath the
vehicle whilst in use. If the ground is wet, place the LD200 on a waterproof
liner.

Batteries and Connections
Batteries are the key to maximum performance from your LD200, if a
battery is too small or not fully charged it may result in de-rated
performance from your LD200.
Battery ratings
Batteries can be rated in one of two ways:
1. CCA = Cold Cranking Ability. This is the amount of power or current
that a battery can deliver for a short period, typically a few seconds. This
how a car battery would normally be rated.
2. Ah = Ampere Hours. This is the maximum amount of energy that can be
stored in a battery; this figure will generally be stated at a particular hour
rate. This is how a deep cycle or storage battery would normally be rated.
100Ah @100hr, this means that when this battery is discharged over
a period of 100 hours, the battery has a capacity of 100Ah. This in
theory means 1 Amp for 100 hours, although this would in practice
result in a totally discharged battery that may not then recover.
To achieve maximum performance from your LD200 you must have a
battery capable of delivering 50 Amps for a short period whilst maintaining
at least 10.5 volts. To increase the capacity of your battery you may need to
join more than one battery together.
•Where batteries are joined
in series, add the voltage of
each battery.
The capacity will equal the capacity of the smallest battery. 2 x 12
Volt 100 Ah batteries connected in series would have a total
capacity of 24 Volts –100 Ah. This would not suit your 12 Volt
LD200.

3. Once a fortnight or as directed in your battery manufacturer, check the
specific gravity (SG) of each battery cell using a hydrometer, to ensure
that all cells are performing correctly and are properly charged. Any
serious imbalance should be reported to your system designer in case
remedial action needs to be taken.
Radio Frequency Interference
Radio Frequency Interference (RFI) can be a problem for owners of inverters.
RFI in a domestic situation may produce noise or interference on a radio or
TV receiver.
Considerable development time has resulted in a reduction of the RFI
generated by the inverter to a level that complies with C-tick requirements.
Compliance to this standard means RFI is low, but how well the inverter
performs in a particular installation can vary. Below are some suggestions to
help reduce the effects of RFI in your installation;
•It is recommended that the power system including the inverter be
housed at least 15 metres from the home.
•Ensure an earth stake is placed as close to the inverter as possible and
connected to the inverter via a short length of wire. See page 2 for
wiring details.
•Avoid running DC cables into the home, if at all possible. If this
cannot be avoided, run DC and AC in separate conduits separated by
as much distance as practicable. All DC wiring should also be kept
together and be as short as possible.
•If your inverter is to be installed in a mobile home or similar, try to
keep your inverter at least one metre away from your radio or audio
equipment. The further the better.

Maintenance
Inverter
Periodic maintenance of your LD200 inverter involves little more than
checking for any obstructions to the black cooling heatsink at the rear of the
inverter. The heatsink must be cleared of any accumulated foreign matter that
may have lodged itself between the fins since the last maintenance check, e.g.
insect nests. Also verify that airflow around the inverter has not become
restricted.
Batteries
1. Every week, carry out a thorough visual inspection of all battery
wiring, taking particular note of the condition of inter-connections
between cells. This maintenance should be carried out in conjunction
with the battery manufacturers recommended maintenance.
Safety Hint
When working on batteries of such high capacity it is
essential that you wear protective clothing, some form of eye
protection and rubber-soled work boots. Please regard your
batteries with a great deal of caution, and if in any doubt,
entrust this work to your supplier / installer.
2. Check that the stainless steel inter-connecting bolts are tight and have
no corrosion. If corrosion is evident, carefully follow the following
procedure.
•Disconnect the system battery fuse before working on the battery
bank.
•Unbolt the stainless steel bolts and nuts of any corroded
connections and thoroughly clean the joint with a wire brush or
file, taking extreme care not to short circuit any battery cells with
any tools.
•Re-assemble and smear a small amount of Vaseline or similar
grease over the surface of the joint to slow down any future
corrosion.

•Where batteries are joined
in parallel, add the capacities
together, the voltage will
remain the same as each
batteries voltage.
2 x12 Volt 100 Ah batteries connected in parallel would have a
capacity of 12 Volts –200 Ah.
Only use identical batteries when joining batteries together.
How long will my battery last
To work out how long your battery will last follow this basic guide.
This guide presumes commencing with a fully charged battery.
Take the total rating of the appliance being run
1 light globe 25watts
1 20 inch TV 67watts
1 VCR 30watts
Total load =122watts
Divide this figure (122) by 10 to know the approximate DC current draw
=12.2Amps
To convert this to Ampere hours, multiply by the number of hours used -
Say 1 hour =12.2Ah
So if we have a 50Ah battery, then with the above example we should have
50 minus 12.2 = 37.8 Ah remaining in the battery.
As a general guide never discharge a battery below 50%. The deeper
a battery is discharged on a regular basis, the less life you can
expect from the battery. See you battery specifications for full
details.

Operation
Three LEDs are provided on the front panel to indicate the operating Status
of the LD200 Inverter.
STATUS indicator LED’s
LED 1, “ON”. Indicates that the inverter is supplying power to the load.
LED 2, DC Volts Low / DC Volts High.
“Flashing” If the inverter shuts down due to low battery voltage ( the battery
is flat) then LED 2 will flash. Charge the battery by starting the vehicle or use
a battery charger. When the battery is charged the battery voltage will rise,
LED 2 will turn OFF and the inverter re-activate.
“Permanently ON” If the inverter shuts down due to high battery voltage
then LED 2 will stay ON. When the battery voltage is reduced LED 2 will
turn OFF and the inverter re-activate.
LED 3, Over temperature / AC Overload.
“Flashing” If the inverter shuts down due to internal components getting too
hot, then LED 3 will FLASH, and will FLASH until the temperature has
dropped to a safe level. LED 3 will then turn OFF and the inverter re-
activate.
•If LED 3 is FLASHING regularly, either reduce the amount of load on
the inverter or, if possible, move the inverter to a cooler location.
“Permanently ON” If the inverter shuts down due to too much AC load
being drawn from it then LED 3 will come ON. The inverter will remain in
this condition for 1 minute after the AC load has been decreased to a safe
level.
•If the inverter remains in this overload condition beyond one minute,
switch 8 (ON /OFF Switch ) should be turned OFF and then back ON to
re-activate the inverter.
