Tighten the screws to the specified torque.
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. Secure the plastic cover back onto the terminal block. The figure below
depicts how it should look once the lug is attached and the protective plastic cover reinstalled.

Feed DC power into the system.
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.
6.
Verify that the power supply is operating.
If connected correctly, when turned on, the LED on the PSU will light up with a Green color
designating normal operation.
AC Version
1.
Ensure there is enough power to supply the system.
The maximum system power consumption is 1466 watts. It is recommended to ensure that
enough power is reserved from the power distribution system before installation. Also, please
ensure that both PSUs have been properly installed before powering up the equipment, as the
S9705-48D is designed to support 1 + 1 power redundancy.
2.
Attach the power cable.
Locate the AC inlet connector on the PSU and plug the AC power cable (250VAC 15A, IEC60320
C19) into the AC inlet connector.
