Environment and Enclosure

Prevent Electrostatic Discharge

ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment,

in overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m

(6562 ft) without derating.

This equipment is not intended for use in residential environments and may not provide adequate

protection to radio communication services in such environments.

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 or be approved for the application if

nonmetallic. 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 the following:

• Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional

installation requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of

protection provided by enclosures.

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.

Octal Label Kit Installation (for PLC processors only)

The octal label kit consists of an octal filter label and a door label. Use these octal labels to replace

the decimal labels that are attached to the I/O modules.

Apply the Octal Filter Label

1. Remove the octal filter label from its paper carrier.

2. Align the octal filter label numbers horizontally to the module color bar and over the

decimal filter numbers.

Refer to Installing Octal Labels on page 7 for filter label placement.

3. Apply the octal label to the filter.

4. Press firmly to be sure that the label adheres properly.

Apply the Octal Door Label

1. Remove the octal door label from its paper carrier.

2. Align the octal label directly over the decimal door label on the inside of the door.

Refer to Installing Octal Labels on page 7 for door label placement.

3. Press firmly to be sure that the label adheres properly.

Removable Terminal Blocks

Colored terminal blocks are removable by loosening the upper and lower retaining screws. Black

terminal blocks are not removable.

TIP

The octal label kit can be obtained from your Allen-Bradley distributor. The octal

kit is ordered based on the catalog number of the I/O module.

Please refer to the SLC 500 Modular Hardware Style User Manual, publication

1747-UM011, for a listing of octal label kit catalog numbers.

ATTENTION: Do not touch or remove the terminal block when the SLC 500 system is

powered. Contact with AC line potential may cause injury to personnel.

Fuse Protection and Blown Fuse Diagnostics

This section describes fusing characteristics for the following modules:

• 1746-OBP16

• 1746-OVP16

• 1746-OAP12

Fuse Protection (1746-OBP16 and 1746-OVP16 modules)

The fuse on the 1746-OBP16 and 1746-OVP16 modules (shown on Location of Jumpers and

Fuses for 1746-OBP16 and 1746-OVP16 Modules on page 9) provides short-circuit protection

for 13 mm2(16 AWG) or larger wiring to external loads. In the event of a short circuit on an

output channel, it is likely that the transistor associated with that channel will be damaged. In

this event, the module should be replaced or the load moved to a spare output channel.

The fuse does not provide overload protection. In the event of an overload on an output channel,

it is likely that the fuse will not blow and the transistor associated with that channel will be

damaged. To provide overload protection for your application, user-supplied fuses should be

installed externally and properly sized to match your individual load characteristics.

Publication 1746-IN027D-EN-P - December 2012

Fuse Protection (1746-OAP12 modules)

A fuse is provided on each common of the 1746-OAP12 module (shown on Location of

Jumpers and Fuses for 1746-OAP12 Module on page 10) for a total of two fuses. The fuses are

designed to protect the module from short-circuit conditions. The fuse does not provide

overload protection. In the event of an overload on an output channel, it is likely that the fuse

will not blow and the output device associated with that channel will be damaged. To provide

overload protection for your application, user-supplied fuses should be installed externally.

The recommended fuse for overload protection is SAN-O HT. Select the fuse rating according

to your load. Do not use HT fuses rated higher than 2.0 Amps.

Blown Fuse Diagnostics

If the fuse blows on the 1746-OBP16, 1746-OVP16, or 1746-OAP12 module, the following

occurs:

• The blown fuse LED indicator will illuminate, provided power (5V DC via backplane

and load power via external supply) is applied to the module.

• A processor error will occur if JP1 connects pins 2 and 3. (See figures on page 9 and

page 10.)
