The installation should be carried out by a qualified installer and in accordance with the regulations of the local distribution system operator.
Step 1
Click onto the DIN rail, according to IEC/EN 60715.
-
Pay attention to the rated diversity factor (RDF) according to IEC/EN 61439-1.
-
It is recommended to mount a box with fuse plugs on the DIN rail next to the fuse(s), to make spare fuse plugs readily available. Replacing a blown fuse plug with a spare one avoids touching the hot fuse.
Step 2
Only use suitable wires:
-
Copper
-
Rigid, stranded or flexible
-
Cross section 1.5an – 35 mm2
Strip the wires. Use ferrules for flexible wires.
Step 3
Feed the main wires at the bottom of the fuse switch disconnector and the consumption at the opposite side. Secure with 3 Nm, using a PZ2 screwdriver.
Use the wiring diagram to connect the wires correctly. For the maximum number of wires that can be connected, refer to the table below.
Make sure to correctly connect the fuses. The load side is the side where the fuses are connected to the installation. The feed side is the side where the power is connected. Reversing the connection poses a an electrocution risk. Always feed at the bottom.
