Page 6: Introduction & Safety Rules
AC power supply to operate correctly. While the power coming from the wall socket outlet is often unreliable, a LP 31 UPS provides the security of completely uninterrupted power. A compact, truly on-line system, the LP 31 UPS protects your equipment from all forms of power interference, including complete power failure. -
Page 7: Storage
If exposed to electrolyte, wash immediately with plenty of water. • Avoid charging in a sealed container. • Never short circuit batteries. When working with batteries, remove watches, rings or other metal objects, and only use insulated tools. OPM_LPS_31E_8K0_20K_1GB_V010.doc 7/40 Operating Manual LP 31 / 8-10-15-20 kVA... -
Page 8: Functional Explanation
2. FUNCTIONAL EXPLANATION 2.1 THE PRINCIPLES OF OPERATION The LP 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. Energy is stored as Direct Current (DC), while input and output energy must be Alternating Current (AC). -
Page 9: Mains Failure
2.4 AUTONOMY TIME The autonomy time, the time the output converter can operate on battery, depends on the capacity of the battery and on the power demand of the equipment supplied by the LP 31 UPS. Estimates of run-times are given. -
Page 10: Automatic Bypass Switch
If a bypass power failure occurs during bypass operation, load power is lost. If the UPS functions under overload conditions it may not be able to protect the load. Figure 3 - Bypass operation: automatic bypass OPM_LPS_31E_8K0_20K_1GB_V010.doc 10/40 Operating Manual LP 31 / 8-10-15-20 kVA... -

This way, testing and maintenance of the UPS is possible without interruption of the power supplied to the load. Figure 4 - Bypass operation: manual bypass OPM_LPS_31E_8K0_20K_1GB_V010.doc 11/40 Operating Manual LP 31 / 8-10-15-20 kVA... -
Page 12: Installation
3. INSTALLATION 3.1 PACKAGE CONTENTS The shipping box contains a LP 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 distributor. If a battery extension pack is to be connected to the UPS, a connection kit is required. - Page 13 Then install the right plus (red) and minus (black) to the right plus and minus of the UPS (terminals 14 and 15). 17. Install all battery fuses at the front of the battery cabinet and in the front of the UPS. OPM_LPS_31E_8K0_20K_1GB_V010.doc 13/40 Operating Manual LP 31 / 8-10-15-20 kVA...
- Page 14 22. If you have not installed a battery pack install all battery fuses at the front. Start at the upper side. The number of fuses shipped with the UPS depends on the rating of the UPS: LP 31 / 8 - 10 kVA = 4 fuses LP 31 / 15 - 20 kVA = 8 fuses 23.

Page 37: Safety
7.4 SAFETY WARNING! When the LP 31 is operating, all parts of the electronics are directly connected to the mains and high voltages are present on all internal parts, including the battery. Even after disconnection from the mains, all parts inside the UPS, including the battery, conduct dangerous voltages (except the ComConnect output). -

Always check these external factors before concluding that your LP 31 UPS is faulty. The front screen will indicate the problem and solution (if the problem is due to environmental circumstances). - Page 39 Q4 NOT OK In case of a system failure the message is displayed for 30 seconds before the self test is repeated. If the faulty situation persists, please contact your dealer. OPM_LPS_31E_8K0_20K_1GB_V010.doc 39/40 Operating Manual LP 31 / 8-10-15-20 kVA...
