3.7.4 AC Output Installation Procedures
Note:
Prior to connecting to the grid, please install an AC circuit breaker
between the converter and the grid.
AC output installation procedures are the following:
Step 1: Confirm the grid voltage and grid frequency are within the
specifications of the converter.
Step 2: Prior to wiring the AC output of the converter, switch the DC input
switch to 0 , switch the grid connection circuit breaker to open
circuit, and install an AC varistor at the AC terminal. The grid
connection circuit breaker can only be closed after the converter
has been electrically installed.
Step 3: Loosen the thread locknuts of the AC output and the system PE,
select the suitable water-proof plugs (4-hole_R, S, T, N and
single-hole PE) from the AC accessories based on the
recommended wire diameters, push the wires through the
water-proof plugs as shown in Figures 4 and 5 (do not damage the
water-proof plug structure to avoid humidity seeping into the
converter’s interior), and wire the AC output according to the
terminal indications of Figure 6. When wiring the AC terminal, 8.0
Nm torque must be applied for proper tightening.
