MicroLogix™ Combo Analog Input/Output Module 4
Publication 0100161-01 Rev. B
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
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.
(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.

Hazardous Location Considerations
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or non-
hazardous locations only. The following WARNING statement applies to use in
hazardous locations.
EXPLOSION HAZARD
 Substitution of components may impair
suitability for Class I, Division 2.
 Do not replace components or disconnect
equipment or change the current switch
selection switch position unless power has been
switched off.
 Do not disconnect equipment unless power has
been removed or the area is known to be non-
hazardous.
 This product must be installed in an enclosure.
 In Class I, Division 2 applications, the bus
connector must be fully seated and the bus
connector cover must be snapped in place.
 In Class I, Division 2 applications, all modules
must be mounted in direct contact with each
other as shown on page 6. If DIN rail mounting
is used, an end stop must be installed ahead of
the controller and after the last 1762 I/O
module.
 All wiring must comply with N.E.C. article 501-
4(b).
