Publication 1769-IN047C-EN-P - April 2003
Install the Controller
The 1769-L20 and 1769-L30 controllers are suitable for use in an industrial
environment when installed in accordance with these instructions. Specifically, this
equipment is intended for use in clean, dry environments (Pollution Degree 2(1))
and with circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3)
Prevent Electrostatic Discharge
Remove Power
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
ATTENTION
!
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins. Follow these
guidelines when you handle the module:
·Touch a grounded object to discharge static potential.
·Wear an approved wrist-strap grounding device.
·Do not touch the bus connector or connector pins.
·Do not touch circuit components inside the module.
·If available, use a static-safe work station.
·When not in use, keep the module in its static-shield bag.
ATTENTION
!
Remove power before removing or inserting this module.
When you remove or insert a module with power applied, an
electrical arc may occur. An electrical arc can cause personal
injury or property damage by:
·sending an erroneous signal to your system’s field devices,
causing unintended machine motion
·causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.

Publication 1769-IN047C-EN-P - April 2003
Panel Mounting Procedure Using Modules as a Template
The following procedure allows you to use the assembled modules as a template
for drilling holes in the panel. If you have sophisticated panel mounting equipment,
you can use the dimensional template provided on page 10. Due to module
mounting hole tolerance, it is important to follow these procedures:
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including any
previously mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8 screw.
5. Place the modules back on the panel and check for proper hole alignment.
6. Attach the modules to the panel using the mounting screws.
7. Repeat steps 1 to 6 for any remaining modules.
DIN Rail Mounting
The controller can be mounted using the following DIN rails:
·35 x 7.5 mm (EN 50 022 - 35 x 7.5)
·35 x 15 mm (EN 50 022 - 35 x 15)
Before mounting the controller on a DIN rail, close the DIN rail latches. Press the
DIN rail mounting area of the controller against the DIN rail. The latches will
momentarily open and lock into place.
TIP If mounting more modules, mount only the last one of
this group and put the others aside. This reduces
remounting time during drilling and tapping of the next
group.

Publication 1769-IN047C-EN-P - April 2003
Battery Handling, Storing, and Transporting
(Cat. No. 1747-BA; containing Sanyo CR14250SE battery cell)
Handling
Storing
Store the lithium batteries in a cool, dry environment, typically +20°C to +25°C
(+68°F to +77°F) and 40% to 60% relative humidity.
Transporting
One or Two Batteries - Up to two batteries can be shipped together within the
United States without restriction. Regulations governing shipment to or within other
countries may differ.
Three or More Batteries - Procedures for the transportation of three or more
batteries shipped together within the United States are specified by the Department
of Transportation (DOT) in the Code of Federal Regulations, CFR49,
“Transportation”. An exemption to these regulations, DOT - E7052, covers the
transport 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 certain conditions are met.
Transport by passenger aircraft is not permitted.
Shipment of depleted batteries for disposal may be subject to specific regulation of
the countries involved or to regulations endorsed by those countries, such as the
IATA Restricted Articles Regulations of the International Air Transport Association,
Geneva, Switzerland.
ATTENTION
!
Do not charge the batteries. An explosion could result or the
cells could overheat causing burns. Do not open, puncture,
crush, or otherwise mutilate the batteries. An explosion may
result and/or toxic, corrosive, and flammable liquids would be
exposed.
IMPORTANT Regulations for transportation of lithium batteries are
periodically revised.
