Installing And Wiring Your Module

Read this chapter to install and wire your module. This chapter covers:

• avoiding electrostatic damage

• determining power requirements

• installing the module

• wiring signal cables to the module’s terminal block

Electrostatic

Damage

Electrostatic discharge can damage semiconductor devices inside this

module if you touch backplane connector pins. Guard against

electrostatic damage by observing the following precautions:

CAUTION

ELECTROSTATICALLY SENSITIVE COMPONENTS

• Before handling the module, touch a grounded

object to rid yourself of electrostatic charge.

• When handling the module, wear an approved wrist strap

grounding device.

• Handle the module from the front, away from the

backplane connector. Do not touch backplane connector pins.

• Keep the module in its static-shield container when not in use or

during shipment.

Failure to observe these precautions can degrade the module’s

performance or cause permanent damage.

Power

Requirements

The module receives its power through the ControlLogix chassis

backplane from the fixed or modular +5 VDC and +24 VDC chassis

power supply. The maximum current drawn by the module is shown in

the table below.
