Environment and Enclosure

This equipment is intended for use in 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 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 flame spread rating or 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, Allen-Bradley publication

• NEMA Standards publication 250 and IEC publication 60529, as applicable, for

Prevent Electrostatic Discharge

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.

explanations of the degrees of protection provided by different types of enclosure.

• Wear an approved wrist grounding strap.

• 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.

ATTENTION

Protective Debris Strip

Do not remove the protective debris strip until after the controller and all the other
equipment near the controller is mounted and wiring is complete.

Once wiring is complete, remove the protective debris strip. Failure to remove the strip
before operating can cause overheating.

Serious injury may occur due to the loss of required safety function.

• Do not use test outputs as safety outputs.

• Do not use DeviceNet standard I/O data or explicit message data as safety data.

• Do not use the safety indicators for safety operations.

• Do not connect loads beyond the rated value to safety outputs or test outputs.

• Wire the controller properly so that the 24V DC line does not accidentally touch the

outputs.

• Ground the 0V line of the power supply for external output devices so that the

devices do not turn on when the safety output line or test output line is grounded.

• Do not dismantle, repair, or modify the controller. Doing so may impair the safety

functions.

Before You Begin

Before you install the controller, set its DeviceNet node address and communication
rate.

IMPORTANT

Turn off power to the controller before setting the node address or communication rate
via the switches.

Do not change the switch settings while the power supply is on. The controller will detect
this as a change in the configuration and will switch to the ABORT mode.

Set the Node Address

Use a small screwdriver to set the DeviceNet node address by using the two rotary
switches on the front panel of the controller. Use care not to scratch the switches.
Values from 00…63 are valid. The default setting is 63.

Follow these steps to set the node address.

1. Set the tens digit of the node address (decimal) by turning the left rotary
switch.

2. Set the ones digit by turning the right rotary switch.

3. To set the node address by using RSNetWorx for DeviceNet software, set the
rotary switches to a value from 64…99.

IMPORTANT

A node address duplication error will occur if the same node address is set for more than
one node.

Setting the Communication Rate

The default communication rate for a DeviceNet network is 125 Kbps.

If you choose to use a different communication rate, the length of the trunkline and
types of cable determine which communication rates your application can support.

DeviceNet Communication Rates and Cable Lengths

125 Kbps 420 m (1378 ft) 500 m (1640 ft) 100 m (328 ft) 156 m (512 ft)

If you change the communication rate of your network, make sure that all devices change
to the new communication rate. Mixed communication rates produce communication
errors.

Set the IP Address for Ethernet Communication

Connect the 1752-L24BBBE controller to the network via a 100 Mbps Ethernet
switch, which will help reduce collisions and lost packets, and increase bandwidth.

The 1752-L24BBBE controller is shipped with BOOTP enabled for setting the IP
address. You can use any commercially available BOOTP server. If you do not have
BOOTP Server capabilities on your network, download the free Rockwell
Automation BOOTP server from http://www.ab.com/networks/bootp.html

To set the IP address by using the Rockwell Automation BOOTP utility, follow
these steps.

.

1. Run the BOOTP utility.

2. Double-click the hardware address of the device you want to configure.

Publication 1752-IN001C-EN-P - January 2009

SmartGuard 600 Controllers 9

3. In the the New Entry pop-up dialog box, type the IP address you want to
assign to the device, and click OK.

The controller appears in the Relation List.

For detailed information on EtherNet/IP communication, refer to the EtherNet/IP
Performance and Application Solution, publication ENET-AP001.

Install the SmartGuard 600 Controller

To install the SmartGuard 600 controller, you must mount it on the DIN rail, wire
the terminals, and make communication connections.

Mount the SmartGuard 600 Controller

IMPORTANT

For effective cooling:

• mount the controller on a horizontal DIN rail. Do not mount the controller vertically.

• provide a gap of at least 50 mm (2.0 in.) above and below the controller and 5 mm

(0.20 in.) on each side.

• select a location where air flows freely or use an additional fan.

• do not mount the controller over a heating device.
