Rack Mounting Installation (PortServer TS 16 Rack and DC Rack)
• 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.
• 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. Disconnect and protective devices to be rated 2A Amps
maximum.
