Note 2: The cavity formed after crimping the conductor crimp strip shall wrap the core wires
completely. The core wires shall contact the terminal closely.
Step 3 Install the crimped OT terminal, flat washer, and spring washer on the M6 welded stud, and
tighten the nut to a torque of 5 N.m using a socket wrench.
To enhance the anti-corrosion performance of the ground terminals, apply silica gel on them after
connecting the ground cable.

6. Connecting AC Output Power Cables
Step 1 Remove the cable gland and the adapter from the AC output connector.
Step 2 Remove the insulation layer of the AC output cable of an appropriate length using a wire
stripper.
The three-phase AC input power cables, neutral cable, and PGND cable must be properly
connected. (No neutral cable connections are involved for the SUN2000-28KTL.)
1. Strip the outer jacket of AC output cable by 55 mm.
2. Cut the core wires of the cables excluding the PGND cable by 2.5 mm.
That is, the core wire of the PGND cable should be 2.5 mm longer than that of other four
cables. For the SUN2000-28KTL, the neutral cable does not connect to the AC output
terminal. Align the neutral cable with the protective jacket and cut it off to facilitate the
stripping of the other four core wires.
3. Strip the insulation layer of each core wires by 12 mm.
Figure 1-18 Connecting an AC output power cable (1) (unit: mm)
The preceding figure shows only how to strip cables for the SUN2000-8KTL to SUN2000-23KTL. For
the SUN2000-28KTL, align the neutral cable with the protective jacket and cut off the neutral cable.
Step 3 Insert AC output cable (L1, L2, L3, N, and PE) into the cable gland and the adapter, as shown
in Figure 1-19 and Figure 1-20.
