5.2 Installation of the DMV-100 Unit in a 19” rack or cabinet
Although it is normally delivered as part of a complete system, already installed and pre-cabled in a new
rack or cabinet, DMV-100 Units can also be ordered separately, as an addition to an existing installation.
5.2.1 Preliminary considerations for installation in a 19” rack or cabinet
The following guidelines will help you plan your equipment rack configuration:
•
Allow sufficient clearance around the rack or cabinet for maintenance.
•
The DMV-100 is designed for a 19” rack installation. A rack space of 2U (3.5”) is required. Enclosed racks
must have adequate ventilation, as each component generates heat. An enclosed rack should have enough
ventilation and air circulation with help of fans and exhaust at adequate locations to keep enclosed rack
pressurized and maintain temperature below 40

C.
•
When mounting a unit in an enclosed rack, make sure that the unit’s frame will not block the intake or
exhaust ports.
•
Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through the unit.
The best placement of the baffles depends on the airflow patterns in the rack.
•
Cabling must be kept away from sources of electrical noise, power lines and fluorescent lighting fixtures.
Keep signal cables apart from power cables.
•
The unit must be kept away from sources of electrically conductive dust, as well as water or moisture.
•
Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the
equipment above. When mounted in an enclosed 19” rack or cabinet, it is suggested to leave at a space of
at least 5 1/4” (3U) above each component for ventilation. Internal fans should also be installed between
units to prevent stagnant air pockets.
•
Side support angles are needed for the installation of the unit.
•
A power source of 85-264V
AC
(47-63 Hz) or 105-370V
DC
must be supplied to the DMV-100 unit.
•
The distance between the DCC-661 conditioner and the DMV-100 unit must not exceed the length of the
power and output cable, which is 30 m (98 ft.).
