A) Strip the end of AC cable outer insulating jacket about 90mm then strip the end of each
wire about 15mm. (as shown in figure 5.17)
Figure 5.17 Strip AC cable
The steps to assemble the AC grid terminals are listed as follows:
Additional explanation:
If the diameter of the protective jacket of the AC cable is less than recommended
(
20K models: 17-25mm; 30K models: 21-30mm) spiral wound tape should be
used to increase the cable diameter to the recommended size.
The
adhesive
tape
is
provided
in
the
accessories.

Please make sure the resistance of cable is lower than 1.5 ohm. If the wire is longer than
100m, it's recommended to use 16-35mm cable. Refer to local electrical codes for wire sizing.

B) Remove the 4 screws on the AC terminal cover and remove the cover. Remove
the screw under the terminal slide and pull out the terminal. (as shown in figure 5.19)
C) Insert the cable through cup nut, water proof sleeve and AC terminal cover into the AC
terminal and use a 4mm Hex wrench to tighten the screws. The torque is 3Nm.( as
shown in
figure 5.20)

If the wire is over 10mm , the L1 and PE can be 5mm longer than the L2, L3, and N. In this
2
way the L1 and PE can be easier connected to the
termina
