Minimum Spacing

Maintain spacing

from enclosure walls,
wireways, adjacent

equipment, etc. Allow
50.8 mm (2 in.) of

space on all sides for
adequate ventilation,

as shown

1762 expansion I/O may be mounted horizontally only.


During panel or DIN rail mounting of all devices, 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.


DIN Rail Mounting

The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50
022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).


Before mounting the module on a DIN rail, close the DIN rail latch. Press the

DIN rail mounting area of the module against the DIN rail. The latch will
momentarily open and lock into place.


Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-

EAH35) for environments with vibration or shock concerns.

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).
