Overview
DataSite 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
(2)
Category II
(IEC 60664-1).
Install your DataSite unit using these installation instructions.
(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.

Most applications require installation in an industrial enclosure to reduce the effects of
electrical interference and environmental exposure. Locate your controller as far as possible
from power lines, load lines, and other sources of electrical noise such as hard-contact
switches, relays, and AC motor drives. For more information on proper grounding guidelines,
see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1
.
You can mount the controller either horizontally or vertically on DIN rails, but horizontal
mounting is recommended for thermal considerations.
Be careful of metal chips when drilling mounting holes for your controller or other
equipment within the enclosure or panel. Drilled fragments that fall into the controller
could cause damage.

Controller Spacing
When mounting the controller, allow 25 mm (1 in.) of space on all sides for adequate
ventilation, as shown below.
DIN Rail Mounting
A small Phillips screwdriver is required for the installation or removal of the controller. The
controller can be mounted to EN50022-35 x 7.5 DIN rails.
Follow these steps to install your controller on the DIN rail.
D
1. Mount your DIN rail.
Make sure that the placement of the controller on the DIN rail meets the
recommended spacing requirements.
2. Loosen the two clamp screws until the clamp can slide out.
Do not remove the screws from the clamp, otherwise they will fall into the
chassis.
3. Place the controller onto the DIN rail, using the rail hooks on the back of the
controller.

4. Slide the clamp out while pushing the controller fully onto the DIN rail (1). When the
controller is properly aligned on the DIN rail (2), slide the clamp in, so that it makes
direct contact with the lower edge of the DIN rail (3).
5. Tighten the clamp screws.
Follow these steps to remove your controller from the DIN rail.
1. Loosen the two clamp screws until the clamp can slide out, taking care not to dislodge

Power Source Requirements
The DataSite modules (1758-FLO301, 1758-FLO302, 1758-RTU201, 1758-RTU202) must

Ground the Module
In solid-state control systems, grounding and wire routing help limit the effects of noise due
to electromagnetic interference (EMI). Run the ground connection from the ground terminal
of the controller to the ground bus prior to connecting any devices. Use AWG #14 wire.
12~24V DC
All devices connected to the RS-232/485 communication port must be referenced to
controller ground, or be floating (not referenced to a potential other than ground). Failure
to follow this procedure may result in property damage or personal injury.

WARNING
You must also provide an acceptable grounding path for each device in your application. For
more information on proper grounding guidelines, refer to the Industrial Automation Wiring
and Grounding Guidelines, publication 1770-4.1
.
Battery Status Check
The DataSite controller uses a lithium battery that allows the real-time-clock (RTC) to
maintain the correct time setting through periods when line power has been removed from
the unit.
Current drain on the battery during these periods is approximately 1 microamp, and the
battery should provide approximately 10 years of operation for the RTC without power
applied.
The DS Settings Utility provides a display of the battery voltage. If the battery voltage should
drop below 2.0 V, contact Rockwell Automation Technical Support (see the back page for
contact information) to arrange for repair/exchange of the DataSite unit.
The lithium battery is not user replaceable.

WARNING

Decommission and Recycle the Battery
The lithium battery is not user replaceable. Follow the instructions in this section to
remove the battery from the DataSite unit for recycling when decommissioning the
DataSite unit.
Dispose of used battery promptly. Keep away from children. Do not disassemble and do
not dispose of in fire.
Refer to the SLC 500 Lithium Battery Installation Instructions, publication 1747-IN515, for
more information on handling, usage, storage, and disposal of lithium batteries.
When you connect or disconnect the battery an electrical arc can occur. This could cause
an explosion in hazardous location installations. Be sure that 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,
