  • Page 6 GE Digital Energy 1. INTRODUCTION & SAFETY RULES 1.1 INTRODUCTION More than ever before, today's advanced electronic equipment, with complex integrated circuits and other sensitive electronics, needs a stable and continuous AC power supply to operate correctly. While the power coming from the wall socket outlet is often unreliable, a LanPro 31 UPS provides the security of completely uninterrupted power.
  • Page 7 GE Digital Energy 1.2.3 Storage Store the UPS in a dry location, storage temperature must be within –20°C to +45°C. If the unit is stored for a period exceeding 3 months, the batteries must be recharged periodically. Connect the unit to the mains and switch it on for a period of approx. 48 hours, minimum every 3 months.
  • Page 8 GE Digital Energy 2. FUNCTIONAL EXPLANATION 2.1 THE PRINCIPLES OF OPERATION The LanPro 31 UPS stores electric energy in batteries housed in the unit. This allows the UPS to supply output power even when the incoming mains power is cut OFF completely.
  • Page 9 GE Digital Energy 2.3 MAINS FAILURE In the event of a mains power failure (i.e. absent or outside tolerance) the system uses the energy reserve stored in the battery to continue to produce AC power, ensuring unbroken output (fig. 2). No interruption or alteration will ever be noticed in the output power.
  • Page 10 GE Digital Energy 2.5 AUTOMATIC BYPASS SWITCH If the output converter is unable to deliver the demanded output power (overload, overtemperature) the bypass switch will automatically transfer the load to the mains. If bypass operation is caused by an overload situation, the UPS will only switch back to output converter if the load is reduced to less than 100%.
  • Page 11 GE Digital Energy 2.6 MANUAL BYPASS SWITCH The system can be bypassed manually using the manual bypass switch located at the rear panel. It is a two-position switch: the normal position is “1”: as in figures 1-2. Position “2” is the service position: the load is directly connected to the mains input.
  • Page 12 The shipping box contains a LanPro 31 UPS and this manual. Inspect the UPS for damage after unpacking. If any damage is present please immediately notify the carrier and the GE Digital Energy distributor. If a battery extension pack is to be connected to the UPS, a connection kit is required.
  • Page 13 GE Digital Energy Installation procedure: Please refer to figure 6 in chapter 4.1 and drawing “TERMINALS” for the location of terminals. Remove the rear grid by loosening the 4 screws. Remove the middle front panel that covers the MCB-switches. Hold the panel at both sides and pull firmly.
  • Page 14 GE Digital Energy 18. In order to calculate the available back-up time related to the actual load, information on the capacity of the battery set is stored in the UPS. As the total battery capacity changes when battery extension packs are installed, the battery capacity must be re-programmed.
