Electrical connections
■ Route LV leads < 42 V and
cables > 42 V/230 V~/400 V~
separately.
■ Strip the insulation from the
cables as close to the terminals
as possible, and bundle tightly
to the corresponding terminals.
■ Secure cables with cable ties.
This ensures that, should there
be an error, for example when
detaching a wire, the wires can-
not drift into the adjacent voltage
area.
