    Critical Power INSTALLATION OF A BATTERY EXTENSION PACK With a battery extension pack you can increase the battery runtime of the UPS. If you do not install a battery extension pack please skip this section and proceed with chapter 4. NOTE The battery extension packs are suitable if connectable to circuits directly connected to mains and compliant with the following:...

    Critical Power START-UP 4.2.1 Start-up, mains available Via front panel: press keypad 'I' (1, fig. 4.1) briefly; LED ‘operation’ (already slowly blinking) will at first blink faster and after a few seconds it will illuminate continuously, indicating that the unit has started up. Via UPS monitoring software: startup after delay, see 4.4.12 for more information.

    Critical Power 4.4.1 Standby The UPS output is off, but the batteries are charging, see 3.6.2 step 5 4.4.2 Normal operation See 4.3.1. 4.4.3 eBoost operation As long as the mains is suitable for the load, the UPS is able to operate in a “green”, high efficiency operating mode: the UPS supplies the load from bypass, while keeping ready for operation in double conversion.
  • Page 16: Overload

    Critical Power 4.4.8 Overload The demanded power exceeds the normal capacity of the UPS. The alarm occurs when the load is > 100%. If the load exceeds 150% the UPS will immediately switch to bypass, assuming that the conditions for a transfer to bypass are fulfilled. If an overload condition between 110-150% persists, the UPS will also switch to bypass operation.
  • Page 17: Use: Setup Mode

    Critical Power USE: SETUP MODE The setup mode can only be entered if the UPS is in ‘standby’ -mode: connected to a live wall outlet and switched off (LED 'operation' blinks). Press keypad 'O' and keep it pressed while pressing 'I' simultaneously. Release both buttons. The setup sequence starts with the setup of the output voltage, indicated by a blinking LED ‘operation’.
  • Page 18: Battery Management

    Critical Power BATTERY MANAGEMENT Maximum battery life and reliability are obtained by the following features:  Quick battery test The quick battery test checks whether the batteries and their wiring are healthy. If a quick battery test shows that the batteries are close to being worn out, a 'bad battery' alarm will be generated (see 4.4.9).

    Critical Power TROUBLESHOOTING Whenever a malfunction occurs, first check external factors (e.g. connections, temperature, humidity or load) to determine whether the problem is caused by the unit itself or by its environment. Subsequently check the thermal circuit breaker: it may be tripped. If so: reset it (see fig. 3.3) and be sure that the UPS is not overloaded. The following chart is a simple troubleshooting checklist only.
