Installing the ONS 15454 M6 Shelf
rating value for AC power ranges between 100 VAC to 240 VAC depending on the standards in various
countries. This product is intended for use on the TN and TT power systems.
For redundant DC power feeds, install both the DC power modules and use four power cables and one ground
cable. For a single power feed, only two power cables (#8 AWG or larger, copper conductor, 194 degrees F
[90 degrees C] minimum) and one ground cable (#6 AWG or larger) are required. Use a conductor with low
impedance to ensure circuit overcurrent protection. However, the conductor must have the capability to safely
conduct any faulty current that might be imposed. For a a DC power supply, the fuse rating must not exceed
40A. For operating voltages, see
The DC power modules have –48 VDC or –60 VDC #8 dual-hole lug power terminals for ANSI. The terminals
are labeled RET and –48 V or –60 V on the DC power modules.
Note
When the ONS 15454 M6 shelf is powered at –60 VDC (nominal), only the TNC, OPT-AMP-C,
OPT-AMP-17-C, OPT-EDFA-17, and OPT-EDFA-24 cards, and the 15454-M6-ECU-60 can be installed.
We recommend the following wiring conventions, but customer conventions prevail:
• Red wire for battery connections (–48 VDC or –60 VDC).
• Black wire for battery return connections (RET).
• The battery return connection is treated as DC-I, as defined in Telcordia GR-1089-CORE, Issue 3.
The ground lug must be a dual-hole type, UL Listed, CSA certified and rated to accept the #6 AWG cable.
Two ground posts with two M5 nuts are provided on the ONS 15454 M6 to accommodate the dual-hole lug.
Note Only use the power cables shipped with the ONS 15454 M6 shelf.
ETSI Power and Ground
The ONS 15454 M6 for ETSI has –48 VDC or –60 VDC power connectors (DSUB for DC power module)
on the DC power module. For redundant DC power feeds, install both the DC power modules and use the two
power cables shipped with the ONS 15454 M6 and one ground cable. For a DC power supply, the fuse rating
must not exceed 40A. For operating voltages, see
For redundant AC power feeds, install both the AC power modules and use the two power cables (right and
left cables) shipped with the ONS 15454 M6 and one ground cable. For an AC power supply, the fuse rating
must not exceed 10A, 15A, or 20A. For North America, the branch circuit protection must be rated 20A. The
overcurrent/short circuit protection must be in accordance with local and national electrical codes. The voltage
rating value for AC power ranges between 100 VAC to 240 VAC depending on the standards in various
countries. This product is intended for use on the TN and TT power systems.
Caution
Only use the power cables shipped with the ONS 15454 M6 shelf.
