Recommended: a copper cable that can withstand 90
°
C (194
°
F) or 105
°
C (221
°
F) and has a
cross-sectional area of 4 AWG for each core wire.
If you connect a ground cable to the PE point on the chassis shell in the scenario with no
neutral wire, you are advised to use a three-core (L1, L2, and L3) outdoor copper cable
(common connection) or three (L1, L2, and L3) single-core outdoor copper cables (connected
through a pipe).
If you connect a ground cable to the PE point in the maintenance compartment in the scenario
with no neutral wire, you are advised to use a four-core (L1, L2, L3, and PE) outdoor copper
cable (common connection) or four (L1, L2, L3, and PE) single-core outdoor copper cables
(connected through a pipe).
If you connect a ground cable to the PE point on the chassis shell in the scenario with a neutral wire,
you are advised to use a four-core (L1, L2, L3, and N) outdoor copper cable (common connection) or
four (L1, L2, L3, and N) single-core outdoor copper cables (connected through a pipe).
If you connect a ground cable to the PE point in the maintenance compartment in the scenario
with a neutral wire, you are advised to use a five-core (L1, L2, L3, N, and PE) outdoor copper
cable (common connection) or five (L1, L2, L3, N, and PE) single-core outdoor copper cables
(connected through a pipe).
OT terminal: M8 (L1, L2, L3, and N) and M6 (PE)
Copper-core cables with copper wiring terminals are recommended. For the requirements on
the cables and terminals made of other materials as well as more detailed cable specifications,
see the
SUN2000-(33KTL, 36KTL, 40KTL)-US User Manual
.
1. Remove an appropriate length of the jacket and insulation layer from the AC output power cable
using a wire stripper. (Ensure that the jacket is in the maintenance compartment.)

cable and neutral wire)
c. Four-core cable (excluding the ground
cable but including the neutral wire)
