Regulations and Directives
Danger
Incorrectly executed electrical
installations can lead to injury
from electrical current and result
in equipment damage.
Connect the power supply and
implement all safety measures
(e.g. RCD circuit) in accordance
with the following regulations:
■ IEC 60364-4-41
■ VDE regulations
■ Connection requirements
specified by your local power
supply utility
Install an isolator in the power supply line
that simultaneously isolates all non-
earthed conductors from the mains with
at least 3 mm contact separation.
We additionally recommend installing an
AC/DC-sensitive RCD (RCD class B
) for DC (fault) currents that can
occur with energy efficient equipment.
Protect the power cable with an external
fuse/MCB 3 A to BS 1362.
Danger
Incorrect core allocation can
result in serious injury and dam-
age to the appliance.
Take care not to interchange
wires "L1" and "N".
Danger
The absence of component
earthing in the system can lead to
serious injury from electrical cur-
rent if an electrical fault occurs.
Connect the appliance and pipe-
work to the equipotential bonding
of the building in question.
