Disconnecting Main Power
WARNING: Explosion Hazard
Do not replace components, connect equipment, or disconnect equipment
unless power has been switched off.
The main power disconnect switch should be located where operators and
maintenance personnel have quick and easy access to it. In addition to
disconnecting electrical power, all other sources of power (pneumatic and
hydraulic) should be de-energized before working on a machine or process
controlled by a controller.
Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 11
Chapter 2 About Your Controller
Safety Circuits
WARNING: Explosion Hazard
Do not connect or disconnect connectors while circuit is live.
Circuits installed on the machine for safety reasons, like overtravel limit switches,
stop push buttons, and interlocks, should always be hard-wired directly to the
master control relay. These devices must be wired in series so that when any one
device opens, the master control relay is de-energized, thereby removing power to
the machine. Never alter these circuits to defeat their function. Serious injury or
machine damage could result.
Power Distribution
There are some points about power distribution that you should know:
• The master control relay must be able to inhibit all machine motion by
removing power to the machine I/O devices when the relay is deenergized. It is recommended that the controller remain powered even
when the master control relay is de-energized.
• If you are using a DC power supply, interrupt the load side rather than the
AC line power. This avoids the additional delay of power supply turn-off.
The DC power supply should be powered directly from the fused
secondary of the transformer. Power to the DC input and output circuits
should be connected through a set of master control relay contacts.
Periodic Tests of Master Control Relay Circuit
Any part can fail, including the switches in a master control relay circuit. The
failure of one of these switches would most likely cause an open circuit, which
would be a safe power-off failure. However, if one of these switches shorts out, it
no longer provides any safety protection. These switches should be tested
periodically to assure they will stop machine motion when needed.
Power Considerations
12 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013
The following explains power considerations for the micro controllers.
About Your Controller Chapter 2
Isolation Transformers
You may want to use an isolation transformer in the AC line to the controller.
This type of transformer provides isolation from your power distribution system
to reduce the electrical noise that enters the controller and is often used as a stepdown transformer to reduce line voltage. Any transformer used with the
controller must have a sufficient power rating for its load. The power rating is
expressed in volt-amperes (VA).
Power Supply Inrush
During power-up, the Micro800 power supply allows a brief inrush current to
charge internal capacitors. Many power lines and control transformers can supply
inrush current for a brief time. If the power source cannot supply this inrush
current, the source voltage may sag momentarily.
The only effect of limited inrush current and voltage sag on the Micro800 is that
the power supply capacitors charge more slowly. However, the effect of a voltage
sag on other equipment should be considered. For example, a deep voltage sag
may reset a computer connected to the same power source. The following
considerations determine whether the power source must be required to supply
high inrush current:
• The power-up sequence of devices in a system.
• The amount of the power source voltage sag if the inrush current cannot be
supplied.
• The effect of voltage sag on other equipment in the system.
If the entire system is powered-up at the same time, a brief sag in the power source
voltage typically will not affect any equipment.
Loss of Power Source
The optional Micro800 AC power supply is designed to withstand brief power
losses without affecting the operation of the system. The time the system is
operational during power loss is called program scan hold-up time after loss of
power. The duration of the power supply hold-up time depends on power
consumption of controller system, but is typically between 10 milliseconds and 3
seconds.
Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 13
Chapter 2 About Your Controller
TIP
Input States on Power Down
The power supply hold-up time as described above is generally longer than the
turn-on and turn-off times of the inputs. Because of this, the input state change
from “On” to “Off” that occurs when power is removed may be recorded by the
processor before the power supply shuts down the system. Understanding this
concept is important. The user program should be written to take this effect into
account.
Other Types of Line Conditions
Occasionally the power source to the system can be temporarily interrupted. It is
also possible that the voltage level may drop substantially below the normal line
voltage range for a period of time. Both of these conditions are considered to be a
loss of power for the system.
Preventing Excessive Heat
Master Control Relay
For most applications, normal convective cooling keeps the controller within the
specified operating range. Ensure that the specified temperature range is
maintained. Proper spacing of components within an enclosure is usually
sufficient for heat dissipation.
In some applications, a substantial amount of heat is produced by other
equipment inside or outside the enclosure. In this case, place blower fans inside
the enclosure to assist in air circulation and to reduce “hot spots” near the
controller.
Additional cooling provisions might be necessary when high ambient
temperatures are encountered.
Do not bring in unfiltered outside air. Place the controller in an enclosure
to protect it from a corrosive atmosphere. Harmful contaminants or dirt
could cause improper operation or damage to components. In extreme
cases, you may need to use air conditioning to protect against heat buildup within the enclosure.
A hard-wired master control relay (MCR) provides a reliable means for
emergency machine shutdown. Since the master control relay allows the
placement of several emergency-stop switches in different locations, its
installation is important from a safety standpoint. Overtravel limit switches or
mushroom-head push buttons are wired in series so that when any of them opens,
the master control relay is de-energized. This removes power to input and output
device circuits. Refer to the figures on pages 17 and 18.
14 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013
About Your Controller Chapter 2
TIP
TIP
WARNING: Never alter these circuits to defeat their function
since serious injury and/or machine damage could result.
If you are using an external DC power supply, interrupt the DC output
side rather than the AC line side of the supply to avoid the additional
delay of power supply turn-off.
The AC line of the DC output power supply should be fused.
Connect a set of master control relays in series with the DC power
supplying the input and output circuits.
Place the main power disconnect switch where operators and maintenance
personnel have quick and easy access to it. If you mount a disconnect switch
inside the controller enclosure, place the switch operating handle on the outside
of the enclosure, so that you can disconnect power without opening the
enclosure.
Whenever any of the emergency-stop switches are opened, power to input and
output devices should be removed.
When you use the master control relay to remove power from the external I/O
circuits, power continues to be provided to the controller’s power supply so that
diagnostic indicators on the processor can still be observed.
The master control relay is not a substitute for a disconnect to the controller. It is
intended for any situation where the operator must quickly de-energize I/O
devices only. When inspecting or installing terminal connections, replacing
output fuses, or working on equipment within the enclosure, use the disconnect
to shut off power to the rest of the system.
Do not control the master control relay with the controller. Provide the
operator with the safety of a direct connection between an emergencystop switch and the master control relay.
Using Emergency-Stop Switches
When using emergency-stop switches, adhere to the following points:
• Do not program emergency-stop switches in the controller program. Any
emergency-stop switch should turn off all machine power by turning off
the master control relay.
• Observe all applicable local codes concerning the placement and labeling
of emergency-stop switches.
Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 15
Chapter 2 About Your Controller
TIP
• Install emergency-stop switches and the master control relay in your
system. Make certain that relay contacts have a sufficient rating for your
application. Emergency-stop switches must be easy to reach.
• In the following illustration, input and output circuits are shown with
MCR protection. However, in most applications, only output circuits
require MCR protection.
The following illustrations show the Master Control Relay wired in a grounded
system.
In most applications input circuits do not require MCR protection;
however, if you need to remove power from all field devices, you must
include MCR contacts in series with input power wiring.

TIP
Module Spacing
Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow
50.8 mm (2 in.) of space on all sides. This provides ventilation and electrical
isolation. If optional accessories/modules are attached to the controller, such as
the power supply 2080-PS120-240VAC or expansion I/O modules, make sure
that there is 50.8 mm (2 in.) of space on all sides after attaching the optional
parts.
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 x 1 mm and
35 x 15 mm (EN 50 022 - 35 x 7.5 and EN 50 022 - 35 x 15).
For environments with greater vibration and shock concerns, use the
panel mounting method, instead of DIN rail mounting.
Before mounting the module on a DIN rail, use a flat-blade screwdriver in the
DIN rail latch and pry it downwards until it is in the unlatched position.
1. Hook the top of the DIN rail mounting area of the controller onto the
DIN rail, and then press the bottom until the controller snaps onto the
DIN rail.
2. Push the DIN rail latch back into the latched position.
Use DIN rail end anchors (Allen-Bradley part number 1492-EAJ35 or
1492-EAHJ35) for vibration or shock environments.
To remove your controller from the DIN rail, pry the DIN rail latch downwards
until it is in the unlatched position.
Panel Mounting
The preferred mounting method is to use four M4 (#8) screws per module. Hole
spacing tolerance: ±0.4 mm (0.016 in.).
Follow these steps to install your controller using mounting screws.
1. Place the controller against the panel where you are mounting it. Make sure
the controller is spaced properly.
2. Mark drilling holes through the mounting screw holes and mounting feet
then remove the controller.
3. Drill the holes at the markings, then replace the controller and mount it.
Leave the protective debris strip in place until you are finished wiring the
controller and any other devices.

WARNING: If you connect or disconnect the communications cable with
power applied to this module or any device on the network, 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.

Connect the RJ-45 connector of the Ethernet cable to the Ethernet port on the
controller. The port is on the bottom of the controller.
Install the microSD Card
1. Insert the microSD card into the card slot.
You can install the microSD card in one orientation only. The beveled
corner should be at the bottom. If you feel resistance when inserting the
microSD card, pull it out and change the orientation.
2. Gently press the card until it clicks into place.
