IRW Series
INFRARED INSPECTION WINDOW
For use on a flat surface area of an enclosure
Preparation
The IRW series is a professional inspection device used in areas where
extreme electrical potentials are present. Use caution at all times. Failure to
follow the safety guidelines below could result in severe personal injury or
death, in addition to equipment loss.
Danger: Risk of Electrical Shock, Burn, or Explosion

Gather all necessary permits prior to installation

Remove power to the equipment prior to installation. Verify that power is
off using an appropriately rated electrical meter

Wear appropriate personal protective equipment (PPE)

Observe and comply with the requirements of local mandates such as
NFPA 70E and CSA Z462

Remove extraneous materials and debris from the installation area after
power has been switched off

It is recommended that the door or panel into which the IR Window is to
be affixed is removed, thereby allowing the installation to take place
remotely, in a safe area

Observe that the minimum dielectric clearance requirements are
maintained when installing the product

Record the transmission rates of the IRW window lens and understand
how this is used to determine component temperature. It is
recommended that the transmission rate be measured on each window
with the actual inspection equipment

It is recommended that the transmission rate of the lens be checked at
six month intervals

Installation Overview
Installation of this IRW infrared window follows the model of a nut and bolt
fastener: A threaded base is inserted through a pre-made hole in the
installation surface. A screw-on nut is then tightened from the opposite side,
holding it in place. Only one hole is required and the sizes are the same as
those used for electrical conduit piping. Industry standard tools can be used
throughout the process.

Installation
1. Use the center punch to mark where the center of the
viewport is to be located
2. Drill the pilot hole using the appropriate drill bit
3. Create the hole in the installation surface. Use the
sizing table to determine the correct knock-out punch
or hole saw.
4. With the locknut removed and the wall gasket still
fitted to the frame base, insert the window assembly
through the cut-out.
5. Install and hand-tighten the locknut in a clockwise
direction with the locknut teeth against the panel
6. Tighten the locknut to a torque of at least 140
in-lbs (180 in-lbs. max). This can typically be
achieved by rotating the locknut one sixth to one
quarter of a turn beyond hand tight. Ensure that
window orientation is maintained during
tightening.
Ensure that the cover is closed and secured before
restoring power to the equipment
