CAUTION: Read and follow safety instructions before removing batteries. This
must be done by a qualified technician due to risk of high voltage and high energy.
• Switch off the UPS (on/off switch) and disconnect it from utility power and critical loads.
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
1. In accordance with local regulations and proper disposal of Ellipse battery(s), it is necessary
to remove them from UPS chassis. This requires removing the top half of the UPS.
2. Observe and note battery connections prior to removal. Follow operations pictured, to take
off the feet (A), remove the 4 screws and top with a phillips screwdriver (B), remove, and
unplug the batteries for recycling (C). Install new batteries and observe polarity (red to "+"
terminal, black to "-" terminal). Be sure to first reconnect the jumper cables between the "+"
of battery one to the "-" of the second and third batteries (see diagram above). It is normal
for a small spark to occur upon connection. Replace top, screws, and feet. Reconnect input

Getting Maximum Battery Life

for 8 hours by connecting to utility power.
This conditions the battery for long life.

to reach a full recharge.
Notes:
1. Ellipse is equipped with a lead-acid
battery(s), which must be disposed of in
accordance with local regulations. MGE

recycling free of charge. Contact us at

section of this manual.
2. Battery life is cut in half for every 15
