Danger
Incorrect electrical installations
can lead to serious injury from
electrical current and result in
appliance 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
■ TAR medium voltage VDE-
AR-N-4110
■ Connection conditions of the
local grid operator
Danger
The absence of system compo-
nent earthing can lead to seri-
ous injury from electric current if
an electrical fault occurs.
The appliance and pipework
must be connected to the equi-
potential bonding of the building.
Isolators for non-earthed conductors
■ The mains isolator (if installed) must
simultaneously isolate from the mains
all non-earthed conductors with a
minimum contact separation of 3 mm.
■ If no mains isolator is installed, iso-
late all non-earthed conductors from
the power supply by the upstream cir-
cuit breaker with a minimum contact
separation of 3 mm.
