DRAKE RMM4 Instruction Manual

The RMM4 is a 1RU rack mount carriage with a built-in power
supply. The assembly accepts up to four mini modules, such
as Video Modulators, Video or Audio Switching Modules, etc.
SPECIFICATIONS:
GENERAL
Power Requirements: ------------------------------ 100 VAC to 240 VAC
Frequency: ---------------------------------------------------------- 50/60 Hz.

0
C.
Output Voltages: ---------------------- +12 VDC @ 1.5A (WHITE wire),
INSTALLATION
Secure modules to the RMM4 using the supplied #4-40 x 1/2"
PAN PHL screws (R. L. Drake part # 3320351) at the four cor-
ners of each module as shown.
Standoffs (16 total), located at the
four corners of each module.
MODULE INSTALLATION
All mini modules install through one of the four openings in the
front panel of the RMM4. Each module is installed with the
handle toward the right-hand side of the RMM4 unit. Each
module should be secured with #4-40 x 1/2" screws via
mounting tabs/holes at the four corners of each module. DC
power cable connections, and any other module-to-module
interconnections, should be made to each module prior to
mounting the RMM4 system into the rack. Observe proper
polarity of cable connectors.

RACK MOUNTING
Adequate ventilation is very important in multi-channel installa-
tions. Units should be spaced apart by at least one panel height
wherever possible, and some air movement is advisable in en-
closed rack cabinets. Excessive heat will shorten component
life and system performance will be degraded without proper cool-
ing.
