1. Ensure there is enough power to supply the system.
The maximum system power consumption is 54 watts. The minimum power distribution unit
fuse requirement is 4 amperes based on the lowest voltage of 36 volts.
2. Attach the power cable.
Locate the DC power screw-type terminal block on the DC PSU. Attach the UL 1015, 14 AWG DC
power cable (not provided within the package contents) to the DC inlet connector on the PSU.

3. Tighten the screws to the specified torque.
Tighten the screws to a torque value of 6.94lbf.in (+/-10%). 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.

4. Feed DC power into the system.
The PSU will immediately output 12V and 5VSB to the system when a -48V DC power source is
applied. The PSU has a built in 6 amperes, fast acting fuse based on the PSU maximum capacity,
