■ 24 Amps per phase (minimum) – 13.0kW, 44,382 Btu/hr
■ 768 Amps per phase (maximum) – 416 kW, 1.4 M Btu/hr
■ Three phase configurations
■ 40 Amps per phase (minimum) – 13.0 kW, 44,382 Btu/hr
■ 280 Amps per phase (maximum) – 416 kW, 1.4 M Btu/hr
Note – Power cabling must be done by a licensed electrician.
Power Configurations
Two power configurations are available for the SL8500 library:
1. N+1 base power configuration
2. 2N power configuration
N+1 Base Power Configuration
The base power configuration contains one system power distribution unit (PDU) and
one N+1 PDU.
■ The system PDU, connected directly to the branch circuit, provides AC power to
three DC power grids and the electronics control module.
■ The N+1 PDU supplies added +48 VDC load sharing power to each of the three DC
power grids and an extra AC-to-DC power supply for the electronics control
module.
The base power configuration provides power to the:
■ Tape drive power supplies
■ Robotic rail power supplies
■ Customer Interface Module power supplies
■ Touch screen local operator panel
■ Electronics control module power supplies
Note – The base power configuration does not offer redundant AC power.
