Precautions When Working With Batteries
CAUTION
LITHIUM ION BATTERY TYPE HAZARD
Make sure to use a lithium ion battery pack that includes a
certified Battery Management System (BMS) with built-in safety
protocols including a pre-charge contactor (see NOTE below).
Follow the instructions published by the battery manufacturer.
Failure to follow these instructions can result in serious injury
or equipment damage.
NOTE: A pre-charge circuit is a featured built-in contactor by
some battery manufacturers which regulates inrush current from
the inverter's capacitors allowing a smooth transition into full
power system operation.
CAUTION
PHYSICAL INJURY HAZARD
This Freedom EX 4000 Inverter/Charger with 48VDC-to-12VDC
Converter is not intended for use by persons (including children)
with reduced physical, sensory, or mental capabilities or lack of
experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
Failure to follow these instructions can result in injury or
equipment damage.
Precautions When Working
With Batteries
IMPORTANT: Battery work and maintenance must be done by
qualified personnel knowledgeable about batteries to ensure
compliance with battery handling and maintenance safety
precautions.
WARNING
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE
AND EXPLOSION FROM VENTED GASES HAZARDS
Always wear proper, non-absorbent gloves, complete eye
n
protection, and clothing protection. Avoid touching your
eyes and wiping your forehead while working near
batteries. See note #4.
Remove all personal metal items, like rings, bracelets, and
n
watches when working with batteries. See notes #5 and #6
below.
Never smoke or allow a spark or flame near the engine or
n
batteries.
Never charge a frozen battery.
n
Never charge a Lithium Ion type battery with an ambient of
n
0 °C (-32 °F) or colder.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.

NOTES:
1. Mount and place the Freedom EX 4000 Inverter/Charger
with 48VDC-to-12VDC Converter unit away from batteries in
a well ventilated compartment.
2. Always have someone within range of your voice or close
enough to come to your aid when you work near a lead-acid
battery.
3. Always have plenty of fresh water and soap nearby in case
battery acid contacts skin, clothing, or eyes.
4. Keep battery terminals clean from corrosion. If battery acid or
corrosion deposit contacts skin or clothing, wash
immediately with soap and water. If battery acid or corrosion
deposit enters your eye, immediately flood it with running
cold water for at least twenty minutes and have someone
within range of your voice or close enough to get medical
attention immediately.
5. Use extra caution to reduce the risk of dropping a metal tool
on the battery. It could spark or short circuit the battery or
other electrical parts and could cause an explosion. Use
tools with insulated handles only.
6. Batteries can produce a short circuit current high enough to
weld a ring or metal bracelet or the like to the battery
terminal, causing a severe burn.
7. When removing a battery, always remove the negative
terminal from the battery first for systems with grounded
negative. Only use this unit in a negative (-) grounded
system. This unit is not designed for a positive (+) grounded
system. Make sure all loads connected to the battery and all
accessories are off so you don't cause an arc.
Precautions When Placing the
Unit
WARNING
FIRE HAZARD
Do not install the inverter/charger/converter or any part of
n
its supplied wiring in engine compartments.
For marine installation, always locate the
n
inverter/charger/converter away from the battery and
mounted separately in a well-ventilated compartment with
adequate space.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.
CAUTION
BURN HAZARD
Avoid touching the external surfaces as they may be hot.
Failure to follow these instructions can result in injury or
equipment damage.
