3. Unscrew the nut of the strain relief (component 5).
4. Remove the cap of the strain relief (component 4).
5. Strip off the insulation of all three conductors of the power cable (phase, neutral
conductor and earth conductor) over a length of 8 mm. The connection terminals are
designed for solid or stranded conductors (18 – 16 AWG).
6. Feed the cables through the strain relief or cable guide. If strain relief is used, feed
the power cable through the strain relief nut (component 5), the cap (component 4)
and the cable gland (component 3).
7. If strain relief is used, insert the cap (component 4) into the cable gland (component
3) and screw the nut (component 5) onto the cable gland. Do not tighten the nut.
8. Open the fuse holder of terminal 1 — to do this, push the fuse holder down (refer to
Figure 7, page 9 ).
9. Connect the phase to terminal 1 (refer to Figure 8, page 10 ) and tighten the screw.
10. Insert the fuse holder again.
11. Open the fuse holder of terminal 4.
12. Connect the neutral conductor to terminal 4 and tighten the screw.
13. Insert the fuse holder again.
14. Connect the front ground cable to terminal 5 and tighten the top screw.
15. For wire connections with a power cable, tighten the nut of the cable gland
(component 3 in Figure 6, page 9 ), so that the cable sits firmly in the strain relief. Do
not tighten the inner conductors of the power cable too tightly under tension (instead
leave a small loop for service work).
16. Position the socket lid again and tighten the four screws.
N O T I C E
Leave the bridges between the terminals 1 and 2 as well as 3 and 4. Both the conductors of the
power cable and the bridges must be connected to the corresponding terminals.
D A N G E R
Risk of electric shock.
A good ground connection to this product is required to make sure that this and all other
connected devices fulfill the safety standards and safety provisions.
N O T I C E
The terminal block for the ground connection has several terminals. The outer screws (top and
bottom screw) are intended for the front terminals.
