DCPower Source Requirements
ADVA Optical Networking recommends installing the PDU on the top of a
rack. The PDU must provide power at nominal –48 VDC to each shelf in
the rack.
This document does not include PDU installation instructions. Refer to
the PDU manufacturer's instructions as needed.
ELECTRIC VOLTAGEWARNING
The DC-powered shelf is not intended to be directly connected to a
centralized DC-power system. The equipment must be switched on or off
using appropriately rated double-pole circuit breakers or single-pole fuses,
which have to be implemented in the building wiring.
l If full redundancy is required, provide two separate power sources for each shelf.
These power sources must be independent and controlled by a separate circuit breaker
at the power distribution point and comply with LVD 2014/35/EC. One power source is
used for Power A (primary power supply) and the other for Power B (the backup power
supply).
l Equipment must be switched on or off via 35 to 40 A (SH12) listed double-pole circuit
breakers or single pole fuses, which have to be implemented in the building wiring
between the shelf's PSM input terminals and the DC power source.
l Each shelf PSM must have its own circuit breaker that is IEC/EN 60898 compliant.
l The circuit breakers are considered the disconnect device and should be easily
accessible all the time.
l The circuit must be protected by a dedicated two-pole circuit breaker. The circuit
breaker should be sized according to the PSM-DC input rating.
l The rack and DC PDU must be connected reliably to protective ground.
l For operation in USA and Canada only:
o
A readily accessible disconnecting device must be incorporated in the building's
installation between the shelf's PSM input terminals and the DC power source.
o
The FSP 3000 C shelves are not intended to be directly connected to metallic tip
and ring outside-plant conductors.
o
The DC-powered shelves employ an isolated DC return (DC-I) design. The DC
battery return terminal shall not be connected to the chassis or frame ground.
o
Site electrical wiring must include a protective ground connection to the –48 VDC
power source in accordance with national and local electrical codes.
