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.
To ensure proper ventilation and air flow for units, provide at least 12 inches (30
centimeters) of clearance on all sides for each unit.
Distribute weight evenly in the rack to avoid overloading.
Elevated operating ambient temperature: If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater
than room ambient temperature. Install rack-mounted equipment in an environment
compatible with the manufacturer's maximum rated ambient temperature (Tmra).
For a rack setup with forced air, the device can run 0-55° C with no extra space above or
below the device (default design of the ConnectPort TS 16 Rack provides 1/16" = 2mm
between devices).
For a rack setup with no forced air, make sure the air in-between devices does not get
warmer than 55°C by providing space between the devices, controlling the ambient
temperature on the rack, distributing weight evenly in the rack to avoid overloading,
checking equipment nameplate ratings before connecting to the supply circuit, and
maintaining reliable earthing of the rack-mounted equipment.
This equipment is for indoor use and all the communication wirings are limited to inside
of the building.
Locate the AC supply source within the same premises as the equipment is to be used.
Check equipment nameplate ratings before connecting to the supply circuit to avoid
overloads that may damage over-current protection devices and supply wiring.
As needed maintain reliable earthing of rack-mounted equipment.
