1. AC terminal block:
• GND: Ground terminal
• N: Neutral terminal (TN/TT) or Phase terminal (IT)
• L: Phase terminal
2. Cable gland
• Use copper wire with a maximum cross-section area of 16 mm
2
/ 6 AWG. Ensure
compliance with the relevant national electrical regulations!
• The AC conductor resistance should be minimized.
• 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 terminal screws is 1.5 Nm
• Double check if the connection is correctly carried out.
• Hand-tighten the gland locknuts to seal the cable gland.
