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.
