4. Telecom Rectifier Working Principles

(1) Figure Conceptual Diagram shows the conceptual diagram. DC power enters solar module through the DC power distribution unit (PDU).

The solar module converts high-voltage into -48VDC. AC power enters rectifiers through the AC PDU.The rectifiers convert the AC power

input into -48VDC power output, which is directed by the DC PDU to DC loads along different routes.

(2) During normal operation, the solar module priority to the DC load and charging batteries. When the solar power is low, the AC power , rectifiers power DC loads and charge batteries. When both the AC and solar are absent, rectifiers and solar modules stop working and

batteries start to power loads. After the AC or solar power power resumes, rectifiers or solar module power DC loads and charge batteries again.

(3) The monitoring unit monitors the running state of each component of the telecom power supply system in real time, and carries out the corresponding intelligent control. When detecting a fault, the monitoring module generates an alarm.

9. Install Subrack

Install the subrack to the 19-inch rack, as shown in Figure below.

Ø Step 1,Remove the plug from the package.

Ø Step 2,Push the plug into the 19-inch rack

Ø Step 3,Install the fixed screw (if the mounting hole of the plug frame ear does not correspond to the position of the floating nut of the frame,

it needs to be adjusted according to the actual installation).

Install Rectifier/Solar module

Ø Step 1, Take out the module from the package.

Ø Step 2, Hold the module handle on the front panel and put the module onto the slot.

Ø Step 3, Push the module slowly to the front panel of the module and flush with the power

distribution panel.

Ø Step 4, Tighten the fixing screw on the module panel so that the module does not come off.

10. Packing and Shipping

Package use free fumigation woodcase which is suitable for export. This package is anti moisture, anti impact and srong to ensure safe transportation.
