■ Connection requirements
specified by the local power
supply utility
■ Protect the power cable with a
fuse/MCB of up to 16 A.
Danger
The absence of component
earthing for the system can lead
to serious injury from electric
current if an electrical fault
occurs.
The appliance and pipework
must be connected to the equi-
potential bonding of the building.
■ 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.
■ In addition, we recommend installing
an AC/DC-sensitive RCD (RCD class
B ) for DC (fault) currents that
can occur with energy efficient equip-
ment.
