Installation
3. Connect the 5-pin DIN plug from the Power Supply Unit DC output to the DC POWER
connector on the rear panel of the DMG1000.
CAUTION
Be sure to connect the DC cable from the Power Supply Unit to the DMG1000 before
connecting the AC Power Cord to the AC power source.
4. Connect the AC Power Cord from the Power Supply Unit to an AC power source. This will

1. Mount the unit in a standard 19” rack. The DMG2000 occupies 1 rack unit (RU).
Rack Mounting Warnings
:
• If installed in a closed or multi-unit rack assembly, the operating ambient temperature of
the rack environment may be greater than room ambient. Therefore, consideration should
be given to installing the equipment in an environment compatible with the maximum
ambient temperature of 40°C.
• Installation of the equipment in a rack should be such that the amount of air flow required
for safe operation of the equipment is not compromised.
• Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
• Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on over current protection and
supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
• 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).
