ATTENTION!
An independent three-phase circuit breaker must be installed on the AC side of
each inverter. Do not install one circuit breaker for multiple inverters!
ATTENTION!
Install a model B leakage curren protection switch with no less than 600 mA
current. Do not share neutral wire when B leakage current protection switch is
installed or else a power grid trip may occur.

Connection of Protection Ground (PGND) Cables
1. Remove the external isolation of the cable to free wires for a length of 120 mm. Remove
the isolation of the individual wires for the length of the OT terminal as shown in the figure
below.

2. Insert the exposed core wires into the crimp area of the OT terminal and crimp them using
hydraulic pliers.
3. Remove the grond screws from the ground points, secure the PE cable using the ground
bolts and tighten the bolts (torque 3 Nm) as shown in the following figure.
