4 Compact 32-point 24V dc Sink/Source Input Module
Publication 1769-IN072A-EN-P - June 2005
Module Installation
Compact I/O is suitable for use in an industrial environment when installed in accordance
with these instructions. Specifically, this equipment is intended for use in clean, dry
environments (Pollution degree 2
(1)
) and to circuits not exceeding Over Voltage Category
II
(2)
(IEC 60664-1).
(3)
Prevent Electrostatic Discharge
Remove Power
(1)
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2)
Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
ATTENTION
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins. Follow these
guidelines when you handle the module:
– Touch a grounded object to discharge static potential.
– Wear an approved wrist-strap grounding device.
– Do not touch the bus connector or connector pins.
– Do not touch circuit components inside the module.
– If available, use a static-safe work station.
– When not in use, keep the module in its static-shield box.
ATTENTION
Remove power before removing or inserting this module. When you
remove or insert a module with power applied, an electrical arc may
occur. An electrical arc can cause personal injury or property damage
by:
– sending an erroneous signal to your system’s field devices, causing
unintended machine motion
– causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical
resistance.
