• Do not short-circuit the device.
• Only use a Lithium compatible charger.
• Observe the positive (+) and negative (–) marks on the device.
• Use DC cables with an appropriate size.
• Do not damage, open or drop the device.
• Do not expose the device to heat or re.
• When you transport the device, make sure that the device is upright and in its original package or equivalent.
• If the device has a leakage, do not touch or swallow the released materials or inhale the released gases. If skin
contact, eye contact or inhalation occurs, take the necessary rst aid measures immediately. Refer to the material
safety data sheet for Lithium-Ion batteries at www.mastervolt.com.
Location specications
Install the device:
-in a well ventilated room,
-protected against rain, snow, water, vapor,
moist and dust,
-away from heat sources,
-in upright position,
-at least 1 cm away from another Lithium-Ion battery,
-Secure the device with mounting straps or equivalent.

Note!
Right out of the box, a jumper wire is set to pins 4 and 5 of the MLI Ultra’s safety relay connector, as a reminder
to install the relay. Connect the jumper wire to pins 4 and 8 and connect the safety relay to pins 1 to 5 (see
drawing below).
Two screws allow the connector block to be temporarily detached from the battery case to make it easier to
connect the wires.
Description
The device is a Lithium-Ion battery to operate heavy loads for an extended period of time.
The device consists of a waterproof electronics box with Lithium-Iron Phosphate cells.

Warning!
The safety relay automatically prevents unsafe overcharge, overdischarge and overheating. The safety relay
opens automatically if built-in thresholds are met. This is called a Battery Safety Event. When voltages and
temperatures are within safe operating range, the safety relay can be reset (REMOTE ON).
If the relay trips again, a non-resettable battery safety event occurred. In that case, set the safety relay to
“LOCK OFF” and contact your supplier or Mastervolt.
