2.3 Power Requirements
The equipment is supplied with either an AC international auto-ranging internal power supply which allows it to be powered
from any 100 to 240 VAC; 50 to 60 Hz source, or a DC supply capable of operating from –36 to –60 VDC.
Check the total current consumption of all equipment on the same line before applying power to the MA4367 system.
Avoid sharing a power source that feeds heavy motors or other equipment, which require large current drains.
2.4 Rack Mounting
The MA4367 system is designed for standard rack mounting in a 19” equipment rack. It requires 4U (7.00”) of vertical rack
space. It should be installed in a rack allowing access to the back of the unit. The upconverter should be isolated from
strong RF radiation emanating from local equipment in the rack. Power line transients that may cause damage to the unit
should be avoided. For adequate ventilation, a space of 1U (1.75”) should be left in the rack, directly above the MA4367
chassis for warm air exhaust.
2.5 Module Installation/Replacement
1. Power off the chassis using the rear panel power switch
2. Disconnect the RF cables from the rear of the corresponding module
3. Using a screwdriver, loosen the corresponding front panel captive screws until the module is free to pull forward
4. Insert the replacement module and retighten the front panel captive screws
5. Turn on the power switch
6. Configure the output frequency and IF/RF levels. Note that after power cycle, the frequency of the MA4061B needs to be re-entered
in order for the power detectors on the MA4070C to lock on properly.
7. Reconnect the rear panel RF cables
