Terminating an Indoor PI Power Cable with an EPC4 Connector
Components of an EPC4 connector (EPC is the
abbreviation for easy power connector.)
(1) EPC4 connector
(2) Scale
(3) Sliding block
(4) Holes for conductors
Push back the sliding blocks until
they are in position. Then, check
whether the conductors are secure
by gently pulling them. If the
conductors slide outward or the
wires of the conductors are
exposed outside the holes, remove
the conductors, cut the split wires,
and then strip and install the
conductors again.
Terminating a PGND Cable with an OT Terminal
Strip the PGND cable.
A: OT terminal
B: PGND cable
C: exposed cable conductor
L1: length of the exposed cable
When you are skillful, you can determine L1
based on the length of the OT terminal lug.
When striping off the insulation layer of the
PGND cable, take care not to damage or nick the
metal conductor of the cable.

Use a screwdriver to push the sliding blocks until
the in-position mark is completely exposed.
Wrong:
The conductor is deviated from the
center of the hole.
