Standards Compliance
•
The equipment meets the applicable requirements of these North American product standards: UL62368-21,
UL62368-1, Telcordia GR-3108-CORE, GR-1089-CORE, GR-487-CORE (converter shelf), and GR-063-CORE.
•
Baffle Required at top of each Converter Shelf Stack in CO and customer premise locations for UL compliance
(Baffles not Required in outside plant cabinets, CEVs, or huts).
•
For multi-shelf systems (up to 3), this equipment has been evaluated for continuous use in ambient temperature
from -40°C to 65°C
16
•
The main output voltage (+/-190V) meets UL60950-21RFT-V requirements. DO NOT CONNECT TO RFT-C
CIRCUITS.
Installation Area
Install only in restricted access areas (dedicated equipment rooms, equipment closets, or the like) in
accordance with articles 110-16, 110-17, and 110-18 of the U.S. National Electric Code (NEC), ANSI/NFPA
No. 70, and pursuant to applicable local codes.
Installation Environment
This equipment is to be used in controlled environments (an area where the humidity is maintained at
levels that cannot cause condensation on the equipment, the contaminating dust is controlled, and the
steady-state ambient temperature is within the range specified).
Installation Category
•
Output circuits are suitable for connection to telephone lines that are equipped with primary lightning
protectors consistent with UL 497.
•
Each copper pair must be provided with protection external to this equipment to a level equivalent to a
CommScope 3C*EW Gas tube primary protector [For example: 3C3EW provides the part in a red color]. This
protector has a voltage breakdown range of 265-465 Volts and an impulse spark over range of <265-700 Volts.
Protectors are provided by the telco customer.
•
The 5-Pin protector must be marked as a "special circuit" consistent with the marking protocol in the users
network.
•
Network equipment and components along the powering circuit shall have suitable insulation resistance at 200
V
from each conductor to ground and a total insulation resistance suitable for 400 V
dc
11
Each shelf has 4 feeds: redundant A and B feeds for each side of the shelf (half shelf). Each feed must be sized to fully power the half shelf in the event of failure of
the other redundant feed.
12
-48V feeds must be wired to limit short circuit current - Table 9.
13
These are maximum situations with each circuit loaded to 100W. No actual or engineered application would load every circuit to this level. In the absence of
detailed information about the network we would recommend using the typical dissipation value of 21 W per card for most applications and 30W per card for
highly loaded networks.
14
Airflow across the entire cross section of the warmest converter shelf.
15
Loop Length is the total length of -48V and -48V Return conductors.
16
-40°C to 55°C for 3 converter shelves and 2 Fan Trays when equipped with QS982A Converters.
