time, then it no longer switches on automatically. The LED 13 remains lit. Press the push button 19 „ON/OFF“ in order to switch on the Inverter.

4.5.3 Overheating (Over Temp.)

If the Inverter has been overloaded for a long time or it has been working in too high surrounding temperatures, it will switch off. The LED 10 „Over Temp.“ is lit and the LED 13 „OFF“ blinks. After cooling down, the inverter switches back on automatically. One minute before the inverter switches off for too high temperature it gives out an acoustic alarm signal. If the Auxiliary Contact has been programmed to detect the high temperature then it synchronizes the relay with the alarm signal. In this way, for example, an emergency back- up system can be started without any break in the energy supply.

4.5.4 Battery Condition

Deep discharge of the lead-acid batteries leads to high losses in capacity and early aging. That is why the battery condition is continuously controlled and supervised. With low volt-age the inverter switches off. The LED 12 „L/H Batt.“ is lit and the LED 13 „OFF“ blinks. When the battery voltage gets up to 12.1V / 24.2V / 48.4V, the Inverter switches on automatically. One minute before the Inverter switches off due to low voltage it gives out an acoustic alarm signal. If the Auxiliary Contact has been programmed to detect the low voltage then it synchronizes the Aux. Contact with the alarm signal. In this way, for example, an emergency back up system can be started without any break in the energy supply.

The low voltage is set to 11.6V / 23.2V / 46.4V. These settings are standard for most batteries. These voltage levels are maintained by the built-in Battery-Management- System of the HP-COMPACT by matching the load and the battery condition.

This setting is comparable with the levels of 10.8V/ 21.6V / 43.2 which are given for most batteries at nominal load.

All voltage levels can be programmed. See the instructions under the section on Programming. Check with your battery supplier which voltage values should be set.
