Connecting Cables

5.2
Connection Method
NOTICE
1. Ensure that all circuit breakers, including upstream output circuit breakers, are switched to OFF
before connecting cables.
2. DT and OT terminals must be coated with a heat shrink tubing.
3. The figure uses routing cables into the cabinet from the top as an example.
4. After cables are connected, seal the cable inlet and outlet holes using firestop putty.
1. Determine the specifications of each
cable based on the Schematic Diagram
delivered with the product and
Appendix A.
2. Route a cable into the cabinet and bind
it to a nearby beam, as shown by (1) in
the figure.
3. Pull the cable to the copper bar to
which the cable will be connected,
determine the cable length, and label
the cable, as shown by (2) in the figure.
a. Mark a line where the cable is to be
cut.
b. Mark a line where the cable is to be
stripped.
4. Pull the labeled cable outside of the
cabinet, and cut off the extra part at the
marked line, as shown by (3) in the
figure.
5. Strip the cable at the marked line,
and prepare terminals.
6. Connect the input cables based on the
Schematic Diagram delivered with the
product, as shown by (4) in the figure.
a. Route the input phase cables, N
cable, and PE cable into the PDC.
b. Connect the input N cable and PE
cable to the corresponding N bar and
PE bar.
c. Connect the phase cables to the
corresponding input terminals of
phases L1, L2, and L3.
7. Connect the output cables based on the Schematic Diagram delivered with the product, as
shown by (4) in the figure.
a. Connect one PE cable and one N cable from the PE bar and N bar inside the PDC to each
load.
b. Connect the output power cable from the wiring terminal of the PDC output terminal block to
the corresponding load.
8. Connect the signal cables based on the Schematic Diagram delivered with the product.
9. Clear foreign matter inside the cabinet.
