ECLIPSE INSTALLATION MANUAL
Function/Requirement Details
Power Supply
Compliance and Loading
The dc power supply must be UL or IEC compliant for a SELV output
(60Vdc maximum).
Check to ensure that connection of an Eclipse system to an existing
dc supply does not overload the supply, circuit protection devices and
wiring.
Where a new dc power supply is to be installed for an Eclipse Node,
the power supply should be rated to supply:
- 12.5A for the INU
- 25A for the INUe
- 15A for the PCC
Cable routing Eclipse tributary, auxiliary and NMS cables are not to be routed with
any AC mains power lines. They are also to be kept away from any
power lines which cross them.
Grounding The INU must be grounded to the station or master ground, which
must be the same ground as used for the dc power supply. Normally
this is achieved by grounding the INU to the ground bar in its
equipment rack or frame. This bar is most often located to one side of
the rack or at rack top or bottom. In turn, the ground bar is grounded
to the station ground.
