4 GuardPLC 1800 Controllers
Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in
IEC publication 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 11. Without appropriate precautions, there may be difficulties
with electromagnetic compatibility in residential and other environments due
to conducted as well as 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, Rockwell
Automation publication 1770-4.1
• NEMA 250 and IEC 60529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure.
, for additional installation requirements.
Install the Controller
Follow these steps to install the GuardPLC 1600 controller.
1. Mount the controller to a DIN rail.
2. Ground the controller.
3. Wire the controller.
4. Make communication connections.
This publication describes these steps in detail.
Rockwell Automation Publication 1753-IN002C-EN-P - June 2010
Mount the Controller
GuardPLC 1800 Controllers 5
IMPORTANT
For effective cooling, mount the controller following these guidelines
• Mount the controller horizontally.
• Provide a gap of at least 100 mm (3.94 in.) above and below the controller.
• Select a location where air flows freely or use an additional fan.
• Do not mount the controller over a heating device.
The controller cannot be panel-mounted. Mount the controller to a DIN rail by following these
steps.
1. Hook the top slot over the DIN rail.
2. Insert a flathead screwdriver into the gap
between the housing and the latch and pull
the latch downward.
3. Hold the latch down as you push the housing
back onto the DIN rail.
4. Release the latch to lock the device onto the
rail.
TIP
To remove the controller from the DIN rail, insert a flathead screwdriver
into the gap between the housing and the latch and pull the latch
downward as you lift the controller off of the rail.

Ground the Controller
The controller is functionally grounded through its DIN rail connection. A protective earth
ground connection is required and is provided through a separate grounding screw on the upper
left of the housing and marked with the grounding symbol .
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
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.

Wire the Controller
The following section describe how to connect the voltage supply and wire the controller’s
digital inputs and outputs.
Connect the Voltage Supply
The 24V DC voltage supply must feature galvanic isolation (in accordance with
EN 60950 or UL 1950) since inputs and outputs are not electrically isolated from the processor.
To comply with CE Low Voltage Directives (LVD) and UL restrictions, you must use either a
Safety Extra Low Voltage (SELV), or a Protected Extra Low Voltage (PELV) power supply to
power this controller. A SELV supply cannot exceed 30V rms, 42.4V peak, or 60V DC under
normal conditions and under single-fault conditions. A PELV supply has the same rating and is
connected to protected earth.
IMPORTANT
IMPORTANT
The supply voltage is connected via a 4-pin connector that accommodates wire sizes up to
2
(14 AWG). You need to connect only one wire to L+ and one wire to L-. Both L+ and
2.5 mm
L- terminals are internally connected, so you can daisy-chain 24V DC power from the
GuardPLC controller to other devices in the panel by using the remaining terminal.
Protect the controller with a slow-blowing fuse.
The GuardPLC 1800 controller can draw up to 9 A. The controller needs 1 A to
operate. Up to 8 A can be used to source voltage power for inputs and
outputs connected to the controller.
ATTENTION: Do not reverse the L+ and L- terminals or damage to the
controller will result. There is no reverse polarity protection.

Safety-Related Digital Inputs
The controller has 24 digital inputs whose status is indicated via status indicators when the
controller is in RUN mode.
LS+ is a voltage source that provides 24V DC for a group of eight dry contact inputs. There are
three groups on the GuardPLC 1800 controller.

8 GuardPLC 1800 Controllers
The safe state of an input is indicated by a 0 signal being passed to the user program logic. If the
test routines detect a fault in the digital inputs, a 0 signal is processed in the user program for the
defective channel. When a fault occurs, the inputs are switched off (0).
Follow the closed-circuit principle for external wiring when connecting sensors. To create a safe
state in the event of a fault, the input signals revert to the de-energized state (0). The FAULT
status indicator activates.
