Attaching The Dc Power Cable; Tightening The Screws; Feeding Dc Power - UfiSpace S9705-48D Hardware Installation Manual

9.3.2 Attaching the DC Power Cable
Locate the DC power screw-type terminal block located on the PSU. Remove the plastic cover
that is protecting the terminal block by pushing from the top or bottom of the cover and
flipping open the cover outwards (Top picture). Secure the two-hole lug (with the DC power
cable attached) to the terminal block (Middle picture). Put plastic cover back on terminal
block to guard against contact with terminals (Bottom picture).
9.3.3 Tightening the Screws
Tighten the screws to a torque value of 14.0+/-0.5kgf.cm. If the torque is not enough, the
lug will not be secure and may cause malfunctions. If the torque is too much, the terminal
block or lug may be damaged. The previous picture depicts how it should look once the lug is
attached and the protective plastic cover reinstalled.
9.3.4 8.3.4. Feeding DC Power
The PSU will immediately output 12V and 5VSB to the system with a -48V DC power source.
The PSU has a built in 80 amperes, fast acting fuse based on the PSU maximum capacity,
which will act as a second tier system protection in case the power distribution unit's fuse is
not functioning.
