8.1 Power Supply Shelf
A Sirius 800 Power Supply Shelf is a separate 2RU assembly which contains up to four
sealed power supply units (PSU’s), see Fig 20. The Power Supply Shelf is rack-mountable
and can be placed above, below or remote from the Sirius frame. The PSU’s are
self-contained and do not contain any serviceable components.
Each PSU requires an individual AC power input connection, i.e. up to four power cables per
2RU shelf.
The current drawn by each PSU is dependent on the:
• Local mains supply voltage.
• Configuration of the router.
• Number of PSU’s installed.
Each individual PSU has auto-sensing inputs.
Each individual PSU is rated:
• 100-240 V AC, 50-60 Hz, 25-15 A.
• Routers powered from 100-120 V AC nominal mains supply
will draw 25 A maximum per PSU.
• Routers powered from 220-240 V AC nominal
will draw 15 A maximum per PSU.
Caution
• Ensure that the power supply shelves are correctly earthed see section 2.7 for
details.
• The power supply units contain dangerous high voltages and are NOT
user-serviceable.
• The DC leads connecting the power supply shelf to the router are capable of
supplying very high electric current. Do not short circuit.
• The power supply shelf has a protective metal mesh cover over the front of the
individual power supply units, this should only be removed by a qualified engineer.
See the Sirius 800 Maintenance & Upgrade manual for details on replacing power
supply units.
• There is one spare DC connector on each power supply shelf and up to two on the
Sirius 830 router frame. Do not remove the covers of the unused connectors.
