inches of open space on each side of the enclosure for proper
ventilation and for cable clearance. If the enclosure is installed
near heat-producing equipment, provisions must be made to
maintain installed module temperatures within their design
specifications.

- NOTE -

The enclosure described in this practice is typically wall-
mounted. Rack mounting in equipment racks is available with
rack-mount kits (Figure 3). See T able 5 for ordering informa-
tion. See Figure 4 for an exploded view of the enclosure.

3.2

Wall Mounting (Typical)

The DSAWM-214 enclosure is typically wall-mounted. The en-
closure has a back panel which serves as a wall-mounting plate
with predrilled mounting holes. When mounting the back
plate, a minimum of #12 up to a maximum of #16 pan-head
type screws with a length of 7/8" to 1" must be used to ensure
stability. Follow the steps below to mount the enclosure on a
wall (also see Figure 3).

1. Remove the back plate from the enclosure by depressing

the black metal push buttons located near the bottom on
each side of the enclosure.

2. Lift and place the back plate on the wall in the desired

mounting location.

3. Mark the four screw hole locations.

4. Set aside the back plate. Drill appropriate pilot holes at

the marked locations before the next step.

5. Partially install the top two screws, leaving approximately

¼-inch protruding for hanging the back panel from the
two keyhole slots provided.

6. Lift the back plate again, align the top keyhole openings

with the two screws and hang back plate on the two pro-
truding screws.

7. Start the two bottom screws and tighten in place. Then

tighten the two top screws in place.

8. Attach the shelf enclosure (hang it) to the mounted back

plate by pressing the two push buttons, positioning the
unit against the back plate, and then releasing the buttons.
To access the plug-in module slots, insert the key in the
front door lock, turn the key and then swing the door open.

3.3

Rack Mounting (Optional)

The DSAWM-214 can be rack mounted in a 19" or 23"
equipment rack with the rack-mount kit # 080-500455.

3.4

Power Connections

The DSAWM-214 can be powered in one of three ways:

Local power via an external -48 VDC power source ap-
plied to the barrier-type TB1 screw terminal strip (located
on the

Telco Termination Module

shipped with and

installed in every enclosure)

Local power via the optional 2555 Power Supply module
placed into Slot 15

Via span power

- CAUTION -

Power applied to TB1 must be wired through conduit. A hole
knock-out is provided on the left side of the enclosure
adjacent to the Telco Termination Module which accepts a
½-inch conduit connector.

3.4.1

-48 VDC Local Power

If local DC power is desired, -48 VDC from an external power
source (battery) can be applied to the enclosure through the
