Explosion Hazards

WARNING

An electrical arc can occur if you:

• insert or remove the CompactFlash card.

• insert or remove the controller while backplane power is on.

• connect or disconnect the battery.

• connect or disconnect the serial cable with power applied to this module

or the serial device on the other end of the cable.

This could cause an explosion in hazardous location installations. Make sure
that power is removed or the area is nonhazardous before proceeding

Preventing Electrostatic Discharge

ATTENTION

This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines when
you handle this equipment.

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in

use.

Removing Module While Under Power (RIUP)

WARNING

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 contacts may create
electrical resistance that can affect module operation.

Environment and Enclosure

ControlLogix Controller and Memory Board 5

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 (6561 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 potential difficulties ensuring
electromagnetic compatibility in other environments due to
conducted as well as radiated disturbance.

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 publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure.

16 ControlLogix Controller and Memory Board

Preparing the Chassis

Before you install a controller:

• install a ControlLogix chassis.

• install a ControlLogix power supply.

Remove the Controller from the Chassis

You can install or remove a controller while chassis power is on and the
system is operating. If you remove the controller, all the devices owned by the
controller go to their configured fault state.

WARNING

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 contacts may create electrical
resistance that can affect module operation.

1. Press the locking tabs on the top and bottom of the controller.

2. Slide the controller out of the chassis.
