    Rack Mounting Installation 1. Attach enclosed bracket ears to rack as shown in illustration. 2. Follow safety precautions when placing Digi CM on rack. Rack Mounting Safety Precautions • Distribute weight evenly in the rack to avoid overloading. • Ensure proper ventilation with at least 12 inches (30 centimeters) of clearance on all sides.
  • Page 150 Rack Mounting Installation • Locate the DC supply source within the same premises as the equipment. • Route away and secure all DC input wiring from sharp edges to prevent chaffing as well as provide strain relief. • Provide a readily accessible disconnect device and protective device a fixed wiring for a DC power supply suitable for the specified rated voltage and current.
