(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 connector PC4/6-STF-7.62-CRWH or PC4/3-STF-7.62-CRWH is
shown as follows.
Before inserting the cable into the opening, make sure that the screw of the terminal is fully loose. Insert the
core of the cable into the opening and tighten the screw with a flat-blade screwdriver. When the cable is not
tightened enough to the connector, the cable or connector may generate heat because of the poor contact.
(When using a cable of 1.5mm2 or less, two cables 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 screwdriver: Phoenix Contact SZS 0.6
3.5). Apply 0.5 to 0.6
N
m torque to screw.
