Step 1
Click onto the DIN rail.
Pay attention to the rated diversity factor (RDF) according to IEC/EN 61439-1.
Step 2
Only use suitable wires:
-
Copper
-
Rigid, stranded or flexible
-
Cross section 1,5 – 35 mm2
Strip the wires. Use ferrules for flexible wires.
Step 3
Optionally, connect the main protection relay and up to 12 fuse switch disconnectors, using TYTAN® HC bus cables (961-9620300).
Feed the main wires at the bottom of the fuse switch disconnector and the consumption at the top. Secure with 3 Nm, using a PZ2 screw driver.
Use the wiring diagram to connect the wires correctly. For the maximum number of wires that can be connected, refer to the table below.
Step 4
Remove the placeholder and insert the fuse link.
4.1 Remove the placeholder.
