LITHIUM BATTERY SAFETY
This section contains basic information regarding safe
storage, disposal, installation, and transportation of lithium
batteries used in your robotic system.
Safety
To ensure proper battery operation and to reduce personal
hazards:
•Use only for intended operation;
•Dispose of cells only according to recommended
procedures;
•Only ship using freight aircraft.
DANGER!
Excessive heat may cause batteries to burn or explode,
therefore:
•Do not charge batteries;
•Do not incinerate, solder, or expose to high
temperatures;
•Do not short positive & negative terminals
together.
Storage
Always store the lithium batteries in a cool and dry place,
typically 20 to 25°C (68.5 to 77°F) at 40% to 60% relative
humidity. Place batteries and a copy of these instructions
away from flammable materials.
Transportation
Each battery contains 0.23 grams of lithium. Two batteries
can ship together within the United States without restriction.
Transportation procedures for transferring three or more
batteries within the United States are in the Department of
Transportation (DOT), Code of Federal Regulations, CFR49,
“Transportation.” An exemption to these regulations,
DOT-E7052, covers transportation of certain hazardous
materials classified as flammable solids. This exemption
authorizes transport of lithium batteries by motor vehicle, rail
freight, cargo vessel, and cargo-only aircraft, providing
meeting certain conditions. Regulations governing shipment
to, or within, other countries may differ from those of the U.S.
A special provision of DOT-E7052 (11th Rev., October 21,
1982, par. 8-a) provides that: Persons who receive cells and
batteries covered by this exemption may reship them
pursuant to the provisions received.
The Code of Federal Regulations, 49 CRF 173.22a, relates
to the use of packaging authorized under exemptions. In part,
you must maintain a copy of the exemption at each facility
where the packaging is in connection with shipment under
the exemption. Shipment of depleted batteries intended for
disposal may be subject to specific regulations under the
IATA Restricted Articles of the International Air Transport
Association, Geneva, Switzerland. NOTE: Periodically
Regulations for transportation of lithium batteries are
changed.
Disposal
For disposal, batteries must be packaged and shipped in
accordance with transportation regulations to a disposal site.

WARNING!
Do not incinerate or dispose of lithium batteries in
general trash collection. Explosion or violet rupture is
possible. Collect batteries for disposal in a manner to
prevent against short-circuiting, compacting, or
destruction of integrity and hermetic seal. Although the
Environmental Protection Agency has no specific lithium
battery regulations at this time, lithium may be
considered toxic, reactive, or corrosive. Persons
disposing of the material are responsible for any hazard
created in doing so. State and local regulations may
exist regarding the disposal of these materials.
BATTERY REPLACEMENT
Your lithium batteries provide memory backup for
approximately five years. Batteries are located in both the
robot base and controller.
DANGER!
Only qualified electricians familiar with high voltage
location within the controller should replace the battery.
Controller
A “Memory Battery Weak” error message appears on the
pendant screen, indicating battery replacement must occur
within 40 hours. If this message occurs within 30 minutes of
power-up following an extended power-off period of more
than two days, replace battery immediately as follows:
1. Set MAIN POWER switch on controller to ON.
2. Open cabinet and remove battery connector and fixing
screw on YIF01 board.
3. Unplug battery from CN110/BAT connection and remove.
4. Replace battery and plug connector into CN100/BAT
connection.
5. Close controller cabinet.
Robot
An “Encoder Battery Weak” error message appears on the
pendant screen, indicating battery replacement must occur
within 40 hours as follows.
NOTE: Connect new battery pack before removing old
one to avoid losing encoder absolute data.
1. Set the MAIN POWER switch on the controller to OFF.
2. Remove mounting screws for the battery pack on the
connector base.
3. Remove battery pack from holder.
4. Connect the new battery pack to the unoccupied
connector.
5. Remove the old battery pack from the connector.
6. Mount the new battery pack on the holder.
7. Securely fix the battery pack on the connector base with
the mounting screws.
