MicroLogix 1200 Analog Output Module 3
Publication 1762-IN016B-EN-P - December 2005
Before Installation
1762 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
(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.
