Install the Module
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)
(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.
ATTENTION
Preventing 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.
•
Wear an approved grounding wriststrap.
•
Do not touch connectors or pins on component boards.
•
Do not touch circuit components inside the equipment.
•
If available, use a static-safe workstation.
When not in use, store the equipment in appropriate static-safe
packaging.
WARNING
If you connect or disconnect the serial cable with power applied
to this module or the serial device on the other end of the cable,
an electrical arc can occur. This can cause an explosion in
hazardous locations. Be sure that power is removed or the area is
nonhazardous before proceeding.
(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.
