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 and
implement all safety measures
(e.g. RCD circuit) in accordance
with the following regulations:
■ IEC 60364-4-41
■ VDE regulations
■ Connection conditions of the
local power supply utility
■ Protect the power cable 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.
