Danger to life due to electric arc
The connecting terminal plate must be firmly screwed to the slot with two screws. If the
connecting terminal plate is not correctly mounted and comes out of the slot, an electric arc
can form. An electric arc can cause life-threatening burns and can cause fire.
• Tighten the screws of the connecting
terminal plate using a flat-blade
screwdriver (blade width:3.5mm
(0.14in)) (torque: 0.3Nm(2.65in-lb)).
• Ensure that the connecting terminal plate is securely in place and the screws are
tightened.
9. Strip off the conductor insulation by 18mm (0.71in).
10. In the case of finely stranded wire, provide each conductor with a bootlace ferrule.
11. Connect the conductors to the connecting
terminal plate in accordance with the labeling.
Here, always connect the positive terminal and
the negative terminal of one string to the same
input.
Useful hint: To connect conductors made of
finely stranded wire, each terminal must be
opened. For this purpose, insert the connector
into the terminal all the way to the lock. Open
the terminal lock then with a flat-blade
screwdriver (blade: 3.5mm (0.14in)) and guide
the conductor as far as it can go in to the
terminal.
12. Ensure that all terminals are allocated to the correct conductors.
13. Ensure that the conductors are plugged completely into the terminals up to their insulation.
Useful hint: To release the conductors from the terminals, the terminals must be opened. To do
this, stick a flat-blade screwdriver (blade width: 3.5 mm (0.14in)) as far as it can go into the
rectangular opening above the terminal.
