Module Installation CompactBlock LDX is suitable for use in a commercial or light
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
(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 analog I/O module
bus connector pins or the terminal block on the
input module. Follow these guidelines when you
handle the module:
•
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 module inits box.
