Chapter 2 Installing
Getting Started
The DC version of the TimeProvider 2300/2700 is to be installed into a rack with
permanent connection to the -48VDC mains. This connection is to be made to a
branch over-current, short-circuit protection device with replaceable fusing of 1.5
amps, maximum. For permanently connected equipment, a readily accessible
disconnect device shall be incorporated in the building installation wiring.
The AC version of the TimeProvider 2300/2700 is to be installed into a rack. The AC
power connection is to be made to a 120 or 240 VAC power receptacle following
local codes and requirements. An external Surge Protective Device is required to be
used with the AC version of the TimeProvider 2300/2700.
Environmental Requirements
To prevent the unit from malfunctioning or interfering with other equipment, install
and operate the unit according to the following guidelines:
Operating temperature: –40Fto 149F (–20 C to 65C) for TP 2300/2700 with
quartz oscillator (OCXO); 23Fto 131F (–5 C to 55C) for TP 2300/2700 with
Rubidium oscillator. Startup temperature > -20C (-4F) for TP 2300/2700 with
OCXO.
Operating Humidity: 5% to 95% RH, maximum, w/condensation
Use only shielded cable for all signal wiring, including I/O, clocks and Ethernet.
Ground appropriately at both ends, or as required by local standards.
Secure all cable screws to their corresponding connectors.
Installation Tools and Equipment
You will need the following tools and equipment to install the TimeProvider
2300/2700:
Standard tool kit
Warning: The intra-building ports of the equipment is suitable for
connection to intra-building or unexposed wiring or cabling only. The
intra-building ports of the equipment MUST NOT be metallically
connected to interfaces that connect to the OSP or its wiring. These
interfaces are designed for use as intra-building interfaces only (Type
2 or Type 4 ports as described in GR-1089-CORE) and require
isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect these
interfaces metallically to OSP wiring.
Caution: To avoid interference, you must consider the
electromagnetic compatibility (EMC) of nearby equipment when you
install the TP 2300/2700.
Electromagnetic interference can adversely affect the operation of
nearby equipment.
