MD808 Mounting Dimensions and Installation Guidelines
Mounting
The SLO-SYN Drive is mounted by fastening its mount ing brackets to a flat surface as shown in Figure 3.1. If the Heat Sink Assembly, part number 221576-001, is mounted against a bulkhead, be sure to apply a thin coating of thermal compound between the heat sink and the mounting surface before fastening the unit in place. Do not use too much thermal compound. It is better to use too little than too much.
NOTE: Case temperature should not exceed +70¡ ¡ C (+158°F). A heat sink, such as Superior Electric Heat Sink Assembly 221576-001, must be used when the drive is operated at a current setting of 4 amperes or more. In this case the unit should be mounted upright (with the cooling fins vertical) , or proper cooling will not occur. Air flow should not be obstructed. Forced air cooling may be required to maintain temperature within the stated limits.
When selecting a mounting location, it is important to leave at least two inches (51mm) of space around the top, bottom and sides of the unit to allow proper airflow for cooling.
It is also important to keep the drive away from obvi ous sources of electrical noise. If possible, locate the drive in its own metal enclosure to shield it and its wiring from electrical noise sources. If this cannot be done, keep the drive at least three feet from any noise sources.
