The installation should be carried out by a qualified installer and in accordance with the regulations of the local distribution system operator.
The images below are for the 3 Pol. version (61-033); the installation for the 3 Pol.+N (61-034) is similar.
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 1,5 – 35 mm2
Strip the wires. Use ferrules for flexible wires.
Step 3
Feed the wires at the top or at the bottom of the fuse. Secure with 3 Nm, using a PZ2 screw driver.
Use the wiring diagram to connect the wires correctly.
Step 4
Remove the placeholder and insert the fuse link. Depending on the chosen fuse link, use the appropriate spacers:
Step 5
Switch ON.
Step 6
Check the fuse within 24 hours after switching ON:
-
The average operation temperature must be less or equal to 35 °C.
-
The terminals must remain secured at 3 Nm.
