Ring-type or fork-type cable lugs can be used. The cable lugs must be insulated in order to
achieve sufficient insulating clearance. Alternatively, the bare zone must be provided with
other insulation means, e.g. shrinking tubes.
The following data must be met:
For voltage connectors
Cable lugs for bolt diameter 4 mm;
max. major diameter 10 mm;
for cross-section 1.0 mm
Use copper conductors only!
Recommended cable lugs series PIDG of Messrs. Tyco Electronics AMP, e.g.
ring-type cable lug
fork-type cable lug
Direct connection with solid bare wire or flexible wire with end sleeves;
for cross-section 0.5 mm
When using one single conductor, the conductor end must be inserted such that it will be
drawn into the contact cavity while tightening the screw.
Use copper conductors only!
Wire strip length solid bare wire 9 mm to 10 mm or 0.354 in to 0.394 in.
max. torque value 1.8 Nm or 16 in-lb.
