HOT This is likely under sustained heavy load conditions since the SE32 shuts down to protect its internal components If you believe that the load is not excessive check around the Inverter case and heatsink for obstructions to air flow as this will cause the Inverter to heat up much quicker and shut down sooner than normal Also check that the clearances around the SE32 are as specified in INSTALLATION on page 2 6 INVERTER PULSES SLOWER THAN NORMAL WHEN IN STANDBY This means that the inverter has not been switched on for approximately 20 minutes and has gone into a power saving mode thus pulsing at about half the normal rate 10 SYSTEM MAINTENANCE To get the optimum performance from your SE32 power inverter particularly under heavy appliance loads it is essential that the battery bank and the DC wiring are all in good condition The small amount of time spent on the below maintenance tasks will maximise the reliability of your system SE32 MAINTENANCE Periodic maintenance of the SE32 inverter involves little more than checking for unobstructed operation of the cooling fan which is located at the rear of the inverter Note that cooling air is drawn in through vents underneath the inverter Suggested inverter maintenance should include 1 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 th
