(4) How to insert the cable into Phoenix Contact connector
POINT
Do not use a precision driver because the cable cannot be tightened with
enough torque.
Insertion of cables into Phoenix Contact connec tor PC4/6-STF-7.62-CRWH or PC4/3-STF-7.62-CRWH is
shown as follows.
Before inserting the cable into the open ing, make sure that the screw of the termina l is fully loose. Insert the
core of the cable into the opening and tighten the scre w with a flat-blade screwdriver. When the cable is not
tightened enough to the connector, the cable or c onnector may generate heat because of the poor c ontact.
(When using a cable of 1.5mm2 or less, two ca bles may be inserted into one opening.)
Secure the connector to the servo amplifier b y tightening the connector screw.
For securing the cable and the connector, us e a flat-blade driver with 0.6mm blade edge thickness and
3.5mm diameter (Recommended flat-blade scre wdriver: Phoenix Contact SZS 0.6 3.5). Apply 0.5 to 0.6
Nm torque to screw.
