Power supply
Direct power supply
Danger
Incorrectly executed electrical
installations can result in injuries
from electrical current and dam-
age to the appliance.
Connect the power supply (see
page 5) and implement all earth-
ing 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
■ Protect the power cable on
site with a fuse/MCB of
up to 16 A.
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 all non-
earthed conductors from the mains
with a minimum contact separation
of 3 mm.
■ If no mains isolator is installed, all
non-earthed conductors must be iso-
lated from the power supply by the
upstream circuit breaker with a mini-
mum contact separation of 3 mm.
