Operation
3.1 Installation
Installation consists of mounting the equipment, making the required electrical connections, and entering
the desired set points.
CAUTION
Remove all power prior to installing the UDR.
UDR Mounting
The UDR is a self-contained unit that can be mounted in four different ways.
CAUTION
When Installing the UDR in enclosed panels or cabinets,
ensure that the maximum operating temperature (122°
F) is not exceeded. The total heat load should be
calculated to determine whether cooling by natural
convection or forced ventilation (i.e. fans) is required.
The heat load for a single UDR Is approximately 96
BTU/hr.
NOTE
Where more than four units are to be mounted in a
cabinet, it is recommended that the center position in
each chassis be left blank to facilitate the flow of cooling
air through the cabinet.
NOTE
For seismic applications, the rear of the chassis must be
supported, or the sides of the chassis must be fastened
together. For further Information, contact Fluke
Biomedical.
1. The first mounting utilizes a 19-inch rack chassis adapter, Victoreen Model 948-1 or 948A-1. This
configuration requires 3.5 inches of rack height and can be used to mount up to three UDRs side by
side. The 948A-1 will accommodate both 84X series analog readouts and 94X series digital
readouts. The 948-1 will accommodate the 94X series digital readouts only. A blank filler panel,
Victoreen Model 948A-2, is available to cover unused mounting positions. Refer to drawing GEL-
948-1 or GEL-948A-1 for mounting dimensions.
2. The second mounting consists of a single channel tabletop enclosure, Victoreen Model 948-3.
Dimensions for the enclosure are 4.5 inches high by 6.8 inches wide by 14.9 inches deep. Refer to
drawing 948-3-5 for mounting dimensions.
3. The third mounting consists of a panel mount enclosure, Victoreen Model 948-9. Cutout dimensions
for this enclosure are 3.75 inches high by 6.45 inches wide; the outside dimensions for the
enclosure are 4.0 inches high by 6.7 inches wide by 13.7 inches deep. Refer to drawing 948-9-5 for
mounting dimensions.
