DC Output
There are 3 different load connection options with the 48-300W Modular Switched Mode Rectifier System:
1. Output terminal block of the distribution unit (only for stand-alone systems) (Figure 19)
2. DC bus at rear of the shelf (Figure 20)
3. Auxiliary DC output (300W max.) on the front of each rectifier (Figure 21)
1. Terminal block with four protected DC outputs:
The rectifiers are connected in parallel:
• If the fuse box is empty, insert a alarm-indicating fuse (2A or 5A or 10A) in the fuse holder of the
distribution unit.
• Insert wires (stripping length 10mm) in the associated position in the spring cage terminal block. A flat
screwdriver can be used to assist in the insertion or removal of these wires.

2. DC Bus at rear side:
A load can be connected directly to the DC bus by making connections to the screw-type connector (M5
inserts), as shown in Figure 20.
