Connection Procedures

Figure 4.3.15: Customer connection area with AC terminals

1. AC terminal block:

GND: Ground terminal

N: Neutral terminal (TN/TT)

or Phase terminal (IT)

L: Phase terminal

2. Cable gland

• The current carrying conductors on the AC side must be rated for the current and have a

cross section area of maximum 16 mm

/ 6 AWG. Ensure compliance with the relevant local

and national electrical regulations!

• The AC conductor resistance should be minimized by selecting as large a size of cable

cross-section area as possible, up to 16 mm

/ 6 AWG.

• Unscrew the cable gland locknut.

• Guide the AC cable through the opening, and connect the conductors to the corresponding

terminals in the connection area:

• Phase conductor (L1 or L2 or L3) to L

• Neutral conductor (TN/TT) or Phase conductor (IT) to N

• Grounded conductor to GND

• Tightening torque of the terminals is 1.5 Nm / 1.11 ft-lbf.

• Double check if the connection is correctly carried out.

• Hand-tighten the gland locknuts to seal the cable gland.

4.3.6. Network Connections

The inverter is equipped with two network interfaces; Ethernet and CAN. Ethernet provides

communication between the integrated web server and a computer, either directly connected

or via a router/switch. CAN allows communication between several inverters.
