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.
