INTRODUCTION
Thank you for your purchase of the Selectronic Sine wave inverter, model WM1500-24V.
Your WM1500 is a state-of-the-art high performance TRUE SINE WAVE DC-AC Inverter.
Many hours of development time have been invested in the WM1500 so that we can provide you with a
reliable high quality inverter. The output from your WM1500 is as good as, if not better than mains
power. If looked after properly, the WM1500 will give you many years of reliable service.
WARRANTY CARD
Before proceeding any further, it is extremely important that you complete your warranty card
NOW. This will enable us to immediately register your 5 year warranty period. By accurately
completing your warranty card, you will provide us with valuable information that will assist us in
keeping up with your alternative energy needs. Please take a few moments to fill in the warranty
card. Your efforts will be greatly appreciated.
INSTALLATION
The installation of your inverter is extremely important. Failure to follow the recommended installation
instructions may void your warranty. If in doubt, ask your supplier.
After unpacking, check for any damage that may have occurred during transit. If there are any signs of
damage, contact your supplier immediately.
The Inverter must be installed in a dry, cool, dust-free environment.
Please leave at least 300mm clearance around the sides and top of the Inverter and approximately
200mm at the base as this will aid the natural cooling of the Inverter. The air vents on the underside of
the WM1500 also need to be kept clear of obstructions.

We suggest that you house your Inverter and other power generating equipment in a purpose built shed
sited remotely from the home, and as far away as possible from any radio transmitters or receivers. Also
make sure that the exhaust from your generator or other sources of heat or fumes are kept well away
from the WM1500. SEIA (Sustainable Energy Industry Association (Australia) Ltd) installation
guidelines must be followed.

You must have a suitable 24V DC battery bank that is maintained and operated to the battery
manufacturer’s recommendation. To ensure operation to WM1500 specification, the battery bank
should have a minimum capacity of 500 ampere hours at the 100 hour discharge rate 24V systems (ask
your supplier if in doubt). Smaller capacity batteries can be used but may result in degraded
performance of the WM1500 under heavy surge conditions.
Installation Example
*SYSTEM FUSE
A system fuse is an extremely important part of any power system, this fuse is designed to give one
point of complete disconnect in case of a serious fault. The fuse should have a sufficient rating so as not
to blow under heavy load conditions. Your inverter will normally be the biggest load in your system, if
this is the case a motor start fuse equal to or slightly higher than the maximum continuous current of the
inverter should be used.
If in any doubt see your supplier or installer.
BATTERIES
High quality deep-cycle batteries offer good performance and are available in a wide variety of
sizes.
DO NOT USE ordinary car batteries or engine starting batteries. If a battery is rated only in Cold
Cranking Amps (CCA) and reserve capacity, it is designed to start an engine. Most hybrid type, wet
cell batteries will have a limited life if deeply discharged. These batteries are described as suitable
for engine starting or deep-cycle applications. Do not use maintenance free, wet cell batteries. They
will not hold up well to deep discharging and repeated cycling.
CONNECTION OF AC AND DC WIRING
IMPORTANT: Before making any wiring connections, check that the circuit breaker on the front
panel is in the OFF position, i.e.; LEVER DOWN.
Your electrician should firstly connect the AC wiring via the three terminal junction box. Carefully
observe the correct connections. Please refer to the diagram on page 4.
BROWN ACTIVE (red dot, right connector)
GREEN/YELLOW EARTH (E, centre connector)
BLUE NEUTRAL (left connector)
The lid of the junction box has knockouts to allow conduit entry. Make sure this connection is tight and
safe. Re fit junction box cover.
NOTE:
ALL AC WIRING MUST BE CARRIED OUT BY A LICENSED ELECTRICIAN AND MUST
CONFORM TO AS3000 WIRING REGULATIONS, OR RELEVANT STANDARDS.

Verify that the circuit breaker on the front panel is in the OFF position, LEVER DOWN.
Now connect the battery cables.

BLACK BATTERY NEGATIVE (-)
These connections should be tight. If using nuts, bolts and washers, they should be stainless steel. At
this point re-check the connections before proceeding any further.
WARNING:
IF THE WM1500 EMITS A VERY LOUD TONE, THE BATTERY LEADS HAVE BEEN CONNECTED IN
REVERSE POLARITY. IMMEDIATELY DISCONNECT THE LEADS AND RECONNECT WITH THE
CORRECT POLARITY. DO NOT, UNDER ANY CIRCUMSTANCES, TURN ON THE BREAKER WHEN THE
BUZZER IS SOUNDING, AS PERMANENT DAMAGE TO THE WM1500 WILL RESULT.
If all is well you can now switch the circuit breaker ON.
