  • Page 4: Batteries

    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).
  • Page 5 Verify that the circuit breaker on the front panel is in the OFF position, LEVER DOWN. Now connect the battery cables. BATTERY POSITIVE (+) 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.

  • Page 6: Operation

    OPERATION STANDBY mode means that the WM1500 is producing pulses of power to sense when an appliance is switched on. This is called the demand start because as soon as the appliance is switched on, the WM1500 will turn on and provide full power to the appliance. The inverter will drop back into standby mode once all loads have been switched off for longer than 10 seconds.

  • Page 7: Demand Start Adjust - Led 5 (Green) On

    LED 1 Stays ON, the inverter has been commanded to provide power to the load (e.g. a light switch has been turned on) so it has gone from SLEEP mode to ON. Once the load has been removed (e.g. the light switch is turned off) the inverter will wait 10 seconds and return to SLEEP mode.

  • Page 9: Handy Hint

    After “23.0 Volts”, the next button press “rolls back” the Low DC Volts Cut-out setting to “20.0 Volts” HANDY HINT It is very important that you become familiar with the functioning of your Inverter. Since most Inverters are not within sight, it is not always easy to know what STATUS your inverter is in. An easy way to determine this is to plug a small child's night-light (neon type) into a power point that is easily visible, or replace any power point with a neon indicator type.

  • Page 10: Fault Finding

    FAULT FINDING 1. INVERTER STAYS ON EVEN WHEN NO APPLIANCE IS BEING USED. Some appliances such as Microwave Cookers or Video Recorders still draw current when not in use. This is to power their displays. This is a common problem known as a "phantom load", but it can be easily overcome with the WM1500.

  • Page 11: System Maintenance

    SYSTEM MAINTENANCE To get the optimum performance from your WM1500 power 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.
