Installation and Connection
3.2.4 Grounding Connections
DANGER!
The inverter must be connected to a protection grounding (PE).
„
Use grounding wiring with a gauge at least equal to that indicated in
„
B.1 on page
The maximum tightening torque of the grounding connections is of 1.7 N.m
„
(15 lbf.in).
Connect the grounding points of the inverter to a specific grounding rod, or
„
specific grounding point or to the general grounding point (resistance ≤ 10 Ω).
The neuter conductor that powers up the inverter must be solidly grounded.
„
however, this conductor must not be used to ground the inverter.
Do not share the grounding wiring with other equipment that operate with
„
high currents (e.g. high power motors, soldering machines, etc.).
3.2.5 Control Board
Plug-in modules are connected to control board. S10 DIP-switch are available in control board,
