1. In a household situation 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 WM Inverter Any inverter mounted under a single skin metal roof is unacceptable as condensation may form under the roof and drip onto the inverter You must have a suitable battery bank 12V DC for WM1400 12 and 24VDC for WM1700 24 that is maintained and operated to the battery manufacturer s recommendation To ensure operation to WM specification the battery bank should have a minimum capacity See table 3a Ask your supplier if in doubt Smaller capacity batteries can be used but may result in degraded performance of the WM Inverter under heavy surge conditions Table 3a Suggested minimum battery size WM 1400 WM1700 240Ah 160Ah 3 1 System Diagram gt gt Regulator Regulator 3 2 Installation Example a Main Switch Earth Leakage CB o oTo A _ oo N E a ELCB Protected Circuits WM INVERTER A 3 uses A 7 Both positive and N negative poles of the battery must be fused unless one pole is earthed Consult your sy2.

3. If you believe that the load is not excessive check around the Inverter case and heatsink for obstructions to airflow as this will cause the Inverter to heat up much quicker and shut down sooner than normal Also check that the clearances around the WM inverter are as specified in the INSTALLATION section of this manual 6 System Maintenance To get the optimum performance from your WM inverter particularly under heavy appliance loads it is essential that the battery bank and the DC wiring all be in good condition The small amount of time spent on the maintenance tasks below will maximise the reliability of your system A 6 1 WM Inverter Maintenance Periodic maintenance of the WM inverter involves little more than checking for unobstructed operation of the cooling fans which are located on the sides of the inverter Note that cooling air is drawn in through the vents in the side of the inverter Suggested inverter maintenance should include Check for unobstructed fan operation Clear away any dust or foreign matter from the fan grill using a soft bristled brush Do not direct high pressure compressed air at the fan blades Note that the fan is designed to come on during heavy power demand Check between fins of the heatsink Clean out any accumulated foreign objects for example insect nests dust build up etc 6 2 Battery Maintenance IMPORTANT A When worki When working on batteries of such high capacity it is essent
