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: –40
F
to 149
F (–20
C to 65
C) for TP 2300/2700 with
quartz oscillator (OCXO); 23
F
to 131
F (–5
C to 55
C) for TP 2300/2700 with
Rubidium oscillator. Startup temperature > -20
C (-4
F) 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.

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.
