(5) 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 connector PC 4/6-STF-7.62-CRWH or PC4/3-STF-7.62-CRWH is
shown as follows.
Before inserting the cable into the opening, make s ure that the screw of the terminal is fully loose. Insert the
core of the cable into the opening and tighten th e screw with a flat-blade screwdriver. When the cabl e 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 cabl es may be inserted into one opening.)
Secure the connector to the servo amplifier by tightening the connector screw.
For securing the cable and the connector, use 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.
