DC Power Supply Precautions
The following precautions must be observed when installing the chassis model with an
internal DC power supply.
1.
Check nameplate ratings to ensure there is no overloading of supply circuits that could
effect over current protection and supply wiring.
2.
In addition, the following must be observed:
a.
Connect the equipment to a 35 to 60 VDC power source that is electrically isolated
from the alternating current source.
b.
Route input wiring to terminal block and secure in such a manner that it is protected
from damage and stress. Do not route wiring past sharp edges or moving parts.
c.
Incorporate a readily accessible disconnect device, with a 3mm minimum contact
gap in the fixed wiring.
d.
Install only in Restricted Access Areas (dedicated Equipment Rooms, Equipment
closets or the like) in accordance with Articles 110-18, 110-26, and 110-27 of the
National Electric Code, ANSI/NFPA 70.
e.
Provide a listed circuit breaker suitable for branch circuit protection of the wiring
and rated maximum 1A @ 48 VDC.
f.
For supply connections, use wires suitable for at least 75 ° C.

Installing the 2-Slot Desktop Chassis (DC)
Use the 2-Slot Desktop Chassis (DC) as a table-top chassis, mount it on a rackmount shelf,
or mount it to a wall surface (brackets are not required).
1.
Install the 2-Slot Desktop Chassis (DC) by placing it on a flat surface.
2.
If mounting on a Rackmount shelf, align screw holes and secure with screws.
The rackmount shelf is sold separately. To purchase the rackmount shelf (part number
LMC5238), call Black Box or visit www.blackbox.com
Rackmounting requires a rackmount shelf for mounting up to three units side by side.
3.
If mounting the chassis on a wall, place two #10 panhead screws (not supplied) on
the wall the distance of the holes on the chassis, and then hang the unit on the
screws.
4.
Attach the cables between the chassis and the device that will be interconnected,
and then plug the unit into a reliable, filtered power source.
