Rockwell Automation 1771-ICD DC(20-60V)Input Module Installation Instructions - Manual (Page 2)

2 DC (20-60V) Input Module Cat. No. 1771-ICD Series B
Publication 1771-5.29 – February 2000
For specific information that the above norm requires, see the
appropriate sections in this manual, as well as the following
Allen-Bradley publications:
•
Industrial Automation Wiring and Grounding Guidelines,
publication 1770-4.1
•
Guidelines for Handling Lithium Batteries, publication AG-5.4
Open style devices must be provided with environmental and safety
protection by proper mounting in enclosures designed for specific
application conditions. See NEMA Standards publication 250 and
IEC publication 529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure.
Your module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. The module requires
250mA from the output of this supply. Add this to the requirements
of all other modules in the I/O chassis to prevent overloading the
chassis backplane and/or chassis power supply.
The dc input module is shipped in a static-shielded bag to guard
against electrostatic discharge damage. Observe the following
precautions when handling the module.
!
ATTENTION: This module is equipped with a
plastic cover that is unique to assembly numbers
961046-01 through 961046-09. (This part number is
located near the backplane edge connector pins on the
component-side of the circuit board.) Do not use this
plastic cover on any other module.
Electrostatic Discharge Damage
!
ATTENTION: Under some conditions, electrostatic
discharge can degrade performance or damage the
module. Observe the following precautions to guard
against electrostatic damage.
•
Wear an approved wrist strap grounding device, or touch a
grounded object to discharge yourself before handling the
module.
•
Do not touch the backplane connector or connector pins.
•
If you configure or replace internal components, do not touch
other circuit components inside the module. If available, use a
static-free work station.
