DESCRIPTION
The WM-10GMT-48 is a Wall Mount 60 Amp 48 VDC power distribution panel that provides up to 10 load circuits protected by
individual GMT series fuses (fuses not included). Each circuit can be fused up to 15 Amps, with a total 10-circuit load of 60 Amps
maximum. Heavy duty DC input connectors provide strong ¼ inch studs to accept up to 60 amps at 48 VDC from a single power
supply. All inputs and outputs are isolated from the frame for use in positive ground, negative ground, or floating applications. Fuses
and LED status indicators, input, output, and alarm connections are all on the front of the unit. One green LED is provided to indicate
power supply status for a bank of ten load circuits. When any fuse fails, a red LED is turned on to indicate the condition, and allow
technicians to quickly find the WM-10GMT with the failed fuse. Form C relay contacts, which are isolated from the frame and power
circuits, indicate when there is a fuse failure by providing normally open and normally closed contacts to activate remote alarm or
monitoring systems. These contacts are available via a barrier strip. Additional DuraComm services are available to customize the WM-
10GMT series distribution panels to your specifications.

INSTALLATION WARNING
The individual user should take care to determine, prior to use or installation, whether this device is suitable, adequate or safe for the
use intended. Since individual applications are subject to great variation, DuraComm makes no representation or warranty as to the
merchantability, suitability or fitness of these units for any specific application.
DO NOT block any of the cooling vents on the sides and always allow adequate ventilation by not installing the unit inside tightly closed
spaces. Physical mounting position is not critical but the cooling vents must not be blocked.
Connect the Power Supply Positive to the red terminal labeled, “Input Positive (+)”.
Connect the Power Supply Negative to the black terminal labeled, “Input Negative (-)”.
Connect your Load to the Screw Terminals (1~ 10), Positive (+) on Upper Terminals, Negative (-) to Lower Terminals.
This completes the installation. Failures require investigation as to cause and/or repair of the unit.
THERE ARE NO USER SERVICEABLE PARTS INSIDE. SERVICE AND REPAIR MUST BE REFERRED TO QUALIFIED
FACTORY PERSONNEL

APPLICATIONS
•Inputs and
outputs are isolated from frame for use in + or
•
Has isolated remote relay contacts for fuse alarms (form C)
•Green LED for DC power on indication
•Red LED for fuse alarm indication

Ferrules can be used as a protection when wiring stranded conductors. Copper ferrules prevent the current transfer from be
