Installation and User Manual

2. strip wires by 7 – 7.5mm at either end;
3. terminate each wire using a suitably rated lug; the lugs must also guarantee the surface distances (see
below);
4. apply a tightening torque of 0.5 Nm to the screws (see Heavy Duty specification). All screws must be fully
tightened, including the unused terminals
: check that the surface distance between adjacent screws, and
adjacent lugs, is greater than 3.2 mm;
5.
connect the shield (P3UP side) to the case of the Heavy Duty connector and to the chassis on the machine
side using suitable terminal blocks or metallic cable clamps. Make sure that the contact surface between the
shields and the machine chassis is ample, free from surface insulation (e.g. paint) and the connections are
kept as short as possible. It is important to guarantee the continuity of the shield even when there are
switches and circuit breakers installed
along the line, making sure that the parts that require shielding in the
vicinity of the switches are kept to an absolute minimum. Make sure that the shield is connected securely to
the Heavy Duty connector case using the dedicated screw (ensure ample contact surface). Do not solder or
weld the shield to the cable clamps or directly to the connector cases;
6. the machine I/O connector must not be inserted/extracted in the presence of voltage/current.
Set-up the Control trip thresholds so that multipl
e commands cannot be tripped simultaneously
during normal working cycles.
