2-4 MX2800 User Manual 61200290L1-1
The following UL requirements must be met during installation of
the MX2800 DC version:
1. The unit must be connected to a reliably grounded -48 VDC
source which is electrically isolated from the AC source.
2. The branch circuit overcurrent protection should be a fuse or
circuit breaker rated -48 V, 15 A.
3. The unit should be installed in accordance with the
requirements of NEC NFPA 70.
4. A readily-accessible disconnect device that is suitably
approved and rated should be incorporated in the fixed wiring.
RACKMOUNT INSTALLATION
The MX2800 can be mounted into a standard 19- or 23-inch
equipment rack. (See Establishing Terminal Connection on page 2-10
for information on terminal configuration.) Follow these steps to
mount your unit into a rack:
1. Prepare the MX2800 mounting ears by scraping the paint away
from the mounting ears’ portion that makes contact with the
rack and the portion where the screw mounts into the side of
the MX2800.
Use copper conductors only.
To ensure proper grounding in 23-inch rack configurations, prepare the
MX2800’s mounting ears for installation by scraping away the
paint.Scraping away the paint exposes the bare metal, allowing the
MX2800 to make proper contact with the rack.
