Connection Procedures
Figure 4.3.15: Customer connection area with AC terminals
• The current carrying conductors on the AC side must be rated for the current and have a
cross section area of maximum 16 mm
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
• 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.
