Machines with frequency-controlled motors
can be incompatible with certain types of
earth leakage circuit breaker. It is important
to know that the machines are designed
to provide a high level of personal safety,
which is why items of external equipment
such as earth leakage circuit breakers
are not necessary. If you still want to con-
nect your machine across an earth leakage
circuit breaker, please remember the follo-
wing:
• contact a skilled, authorised installation
company to ensure that the appropriate
type of breaker is chosen and that the
dimensioning is correct
• for maximum reliability, connect only one
machine per earth leakage circuit breaker
• it is important that the earth wire is
properly connected, including to the earth
leakage circuit breaker.
In instances where the machine is not equipped
with an omni-polar switch, one must be installed
beforehand.
Mount a multi-pole switch prior to the machine
to facilitate installa tion and service opera tions.
The connecting cable should hang in a gentle
curve.
Fuse size, see table.
When connecting to a terminal block, the con-
nection cable shell must be stripped 10-11 mm.
The cable area must be at least 0.5 mm2 and no
more than 4 mm2 (AWG12/AWG20). The termi-
nal block used is a spring loaded cage clamp.
Single-phase connection:
Connect the earth and other two wires as shown
in example in the figure.
