Installation

1762 I/O is suitable for use in an industrial environment whe n installed in accord an ce with thes e in struction s . Sp e ci fic ally, this equipm en t is in tended for

use in clean, dry environmen ts (Pollution degree 2 exceeding Over Vo ltage Category II

(2)

(IEC 60664-1).

Prevent Electrostatic Discharge

) and to circuits not

(3)

Remove Power

ATTENTION:

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 de vice.

• Do not touch the bus connector or connector pins.

• Do not touch circuit components insid e the module.

• If av ailable, use a static-safe work s tation.

• When not in use, keep the module in its static-shield box.

ATTENTION:

this module. When you remov e or install 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

• causing permanent damage to the module’s circuitry

Electrical arcing causes excessive wear to contacts on both the module and its mati ng connector. Worn contacts may create electri cal resistan c e.

Electrostati c discharge can damage integrated

Remove po wer before removing or installing

(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.

Mounting

ATTENTION:

the module and a ll other e qui pment near t he module is mounte d a nd

wiring is complete. Once wiring is complete and the module is free of debris, carefully remove protective debris strip. Failure to remove strip before operating can cause overheating.

Minimum Spacing

Main ta in s p acing from enclosure walls, wireways, adjacent equipment, et c. Allow

50.8 mm (2 in.) of space on all side s for ad eq u at e ventilation, as sho wn:

Note:

1762 expansion I/O ma y be mounted horizontally only.

ATTENTION:

be sure that all debris (metal chips, wire strands, etc.) is kept from

falling into the module. Debris that falls into the module could cause damage when power is applied to the module.

Do not remove protective debris strip until after
