Warning

Read and understand all safety information
before installing and using this product.

To reduce the risk of fire or electric shock
which could result in serious personal injury or
death:

! Follow all product and accessory installation

instructions.

! Consideration should be given to the connection of

the equipment to the supply circuit and the effect that
overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should
be used when addressing this concern.

! Reliable earthing of rack-mounted equipment should

be maintained. Particular attention should be given to
supply connections other than direct connections to
the branch circuit (e.g., use of power strips).

Caution

To reduce the risk of fire which may result in
minor or moderate injury or cause property
damage:

! Use the materials provided so that installation of the

ET unit will not result in a hazardous condition due to
uneven mechanical loading.

that the amount of air flow required for safe operation
of the equipment is not compromised.

Mounting using the rack adapter

Important

If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment
may be greater than room ambient. Therefore,
consideration should be given to installing the equipment
in an environment compatible with the manufacturer’s
maximum rated ambient temperature.

To install the rack adapter in the 19-inch rack, follow
these steps:

1. To determine where to attach the clip nuts to the

rack, hold the rack adapter in the rack where you
want to mount the ET unit. Fasten the clip nuts
on the rack so that they match the locations of the
slots in the sides of the rack adapter.

The clip nuts will "clip" to the rack; screws and
washers are not required.

4. On each of the twelve #10-32 panhead machine

screws, first put on a lock washer and then put on
a flat washer.

5. Using a No. 2. Phillips screwdriver, attach each

screw (with lock washer and flat washer) through
the holes in the rack adapter and into the back of
the bezel of the ET unit.

2. Place the ET unit face down on a padded bench

or other protected surface.

3. Fit the rack adapter over the back of the ET unit,

against the back of the bezel.

6. Tighten each screw to a torque of 12 inch-

pounds.

7. If your unit requires security screws (available as

an option from 3M Touch Systems), insert them.

8. Pick up the rack adapter with the ET unit

attached and fit it to the rack. Position it to match
the locations of the clips installed earlier.

9. Fasten the adapter/ET unit to the clip nuts in the

rack with the eight slotted #10-32 x 5/8-inch
countersunk machine screws with a cup washer
on each screw.

10. Connect your data and power cables.
