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.
Check equipment nameplate ratings before connecting to the supply circuit
to avoid overloads which may damage over-current protection devices and
supply wiring.
Maintain reliable earthing for rack-mounting equipment, especially for
supply connections.
Install equipment in Restricted Access Areas only (dedicated equipment
rooms/closets) in accordance with Articles 110-16, 110-17, and 110-18 of
the National Electrical Code, ANSI/NFPA 70.
Connect equipment to a DC supply source (reliably earthed) that is
electrically isolated from the AC source.
Directly connect the equipment chassis to the DC supply system-grounding
electrode conductor or a bonding jumper from a grounding terminal bar (or
bus) that is connected to the DC supply system grounding electrode
conductor.
Contain equipment that has a connection between the grounded conductor
of the same DC supply circuit, the grounding conductor, and also the point
of grounding of the DC system in the same immediate area. Do not ground
the equipment elsewhere.
Rack shown in illustration is
not included with Digi CM.
