Attach the 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. Secure the one-holed lugs (with the DC power cable
attached) to the terminal block as depicted in the following figure.
Figure 25.
4.
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.

5.
Feed DC power into the system.
The PSU will immediately output 12V and 5VSB to the system with a -40V to -75V DC power
source. The PSU has a built in 60A, 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.
