Environment and Enclosure Information
ATTENTION
Environment and Enclosure
This equipment is intended for use in a Pollution Degree 2 industrial environment, in
overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m
(6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions, there may be difficulties with
electromagnetic compatibility in residential and other environments due to conducted and
radiated disturbances.
This equipment is supplied as open type equipment. It must be mounted within an enclosure
that is suitably designed for those specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from accessibility to live parts.
The enclosure must have suitable flame-retardant properties to prevent or minimize the
spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if
non-metallic. The interior of the enclosure must be accessible only by the use of a tool.
Subsequent sections of this publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for additional installation
requirements, Allen-Bradley publication 1770-4.1
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure.

Install a CompactFlash Card
WARNING
When you insert or remove the CompactFlash card an electrical arc can occur.
This could cause an explosion in hazardous location installations. Be sure that
power is removed or the area is nonhazardous before proceeding.
ATTENTION
If you are not sure of the contents of the CompactFlash card, before you install
the card, turn the keyswitch of the controller to the PROG position. Depending
on the contents of the card, a power cycle or fault could cause the card to load
a different project or operating system into the controller.
1. Turn the keyswitch to the PROG position.
2. Open the door of the controller.
3. Push the CompactFlash latch to the left.
4. Insert the CompactFlash card with the A-B logo pointing left.
5. Release the latch and make sure it slides over the CompactFlash card.

Connect the Battery
This controller contains a lithium battery, which is intended to be replaced during
the life of the product.
WARNING
ATTENTION
To maintain the memory of the controller while the controller is without power,
connect a battery. Follow the procedure for both the 1756-L6xS controller and
1756-LSP safety partner.
IMPORTANT
Follow these steps to install a new 1756-BA2
battery:
1. Insert the battery as shown.
When you connect or disconnect the battery, an electrical arc can occur. This
could cause an explosion in hazardous location installations. Be sure that
power is removed or the area is nonhazardous before proceeding.
For safety information on the handling of lithium batteries, including handling
and disposal of leaking batteries, see Guidelines for Handling Lithium
Batteries, publication
Store batteries in a cool, dry environment. We recommend 25 °C (77 °F) with
40%…60% relative humidity. You may store batteries for up to 30 days
between -45…85 °C (-49…185 °F), such as during transportation. To avoid
possible leakage, do not store batteries above 60 °C (140 °F) for more than
days.

Connect only a 1756-BA2 battery to the controller. If you connect a different
battery, you may damage the controller.

Install the Controller into the Chassis
GuardLogix Controllers 9
WARNING
1. Insert the key into the 1756-L6xS controller.
2. Turn the key to the PROG position.
When you insert or remove the module while backplane power is on, an
electrical arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contact may create electrical
resistance that can affect module operation.

The 1756-LSP safety partner does not have a keyswitch.
3. Align the circuit board with the top and
bottom guides in the chassis.
4. Slide the controller into the chassis.
The controller is fully installed when it is
flush with the power supply or other
installed modules and the top and
bottom latches are engaged.
IMPORTANT
You must install the 1756-LSP safety partner in the slot immediately to
the right of the 1756-L6xS controller. Follow steps

Because the GuardLogix controller is a 1oo2 controller (two processors), we
strongly recommend that both controller batteries be replaced at the same time.
Follow this procedure to replace the battery.
1. Turn on the chassis power.
IMPORTANT
If you remove the battery and lose power, the project in the controller
will be lost.
2. Determine if the battery shows signs of leakage or damage.

3. Remove the old battery.
4. Dispose of the old battery in accordance with local regulations.
ATTENTIONDo not incinerate or dispose of lithium batteries in general trash
collection. They may explode or rupture violently. Follow all local
regulations for disposal of these materials. You are legally responsible
for hazards created during disposal of your battery.
This product contains a sealed lithium battery which may need to be
replaced during the life of the product.
At the end of its life, the battery contained in this product should be
collected separately from any unsorted municipal waste.
