Installation
Ventilation
The DM-TX-300N/-F should be used in a well-ventilated area. The venting holes
should not be obstructed under any circumstances.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consider using
forced air ventilation and/or incrementing the spacing between units to reduce
overheating. Consideration must be given if installed in a closed or multi-unit rack
assembly since the operating ambient temperature of the environment may be greater
than the room ambient temperature. Contact with thermal insulating materials should
be avoided on all sides of the unit.
Rack Mounting
The DM-TX-300N/-F can be mounted in a rack or stacked with other equipment.
Two “ears” are provided with the DM-TX-300N/-F so that the unit can be rack
mounted. These ears must be installed prior to mounting. Complete the following
procedure to attach the ears to the unit. The only tool required is a #1 Phillips
screwdriver.
WARNING:
To prevent bodily injury when mounting or servicing this unit in a
rack, take special precautions to ensure that the system remains stable. The following
guidelines are provided to ensure your safety:
•
When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
•
If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE:
If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
NOTE:
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).
To install the ears:
1. There are screws that secure each side of the DM-TX-300N/-F top cover.
Using a #1 Phillips screwdriver, remove the three screws closest to the front
panel from one side of the unit. Refer to the diagram following step 3 for a
detailed view.
2. Position a rack ear so that its mounting holes align with the holes vacated
by the screws in step 1.
3. Secure the ear to the unit with three screws from step 1, as shown in the
following diagram.
