Installation Manual

• Thread the screw through the spring lock
washer, the clamping bracket and the
washer.
• Guide the equipment grounding conductor between the washer and clamping bracket
and tighten the screw with a Torx screwdriver (TX 25) (torque: 6Nm ± 0.3Nm
(53.10in-lb ± 2.65in-lb)).
7. Plug the connecting terminal plate for connecting
the outlet for secure power supply operation into
the SPS slot in the inverter and tighten it with a
flat-blade screwdriver (blade width: 3.5 mm
(0.14 in)).
8. Ensure that the connecting terminal plate is securely in place.
9. Strip off the conductor insulation by max. 15mm (0.59in).
10. In the case of finely stranded wire, provide the conductors L and N with a bootlace ferrule.
11. Connect the conductors L and N to the
connecting terminal plate in accordance with the
labeling.
Useful hint: To connect conductors made of
finely stranded wire, the terminals must be
opened. To do this, stick a flat-blade screwdriver
(blade width: 3.5 mm (0.14in)) as far as it can
go into the rectangular opening above 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 (0.14in)) as far as it can go into the
rectangular opening above the terminal.
Connect the switch for secure power supply operation
