Electrical Connections And Equipotential Bonding - GEM KMG Series Installation And Maintenance Manual

6 • ELECTRICAL CONNECTIONS AND EQUIPOTENTIAL BONDING
6.1 • As this oven is a type X appliance (oven
without power cable and plug), the cable
and other hardware needed to make the
connection to the electrical power supply
must be provided by the installer. The cable
must satisfy the requirements indicated in
table 1 "General data". As already mentioned,
the oven must be connected to the power
supply by way of a multiple pole main isolating
switch ensuring a gap between open contacts
of at least 3 mm on each pole.
6.2 • To gain access to the AC mains connection
terminal board, the right hand panel of the
casing must be removed by undoing the fixing
screws (all models).
6.3 • The cable must be fed in from beneath the
clamp. The individual wires are then fastened
to the corresponding terminals of the terminal
board. The earth wire must be longer than the
other wires, so that in the event of the cable
being jerked or the clamp broken, the live
wires will disconnect first.
Check the efficiency of the isolating switch.
6.4 • The oven must be kept in an equipotential
system. This connection is made by wiring a
conductor of nominal cross section 10 mm
the corresponding terminal at the back of the
oven, which is marked with the internationally
recognized symbol.
All appliances in the room are bonded in this
way and connected to the earth system of the
building.
6.5 • The electrical safety of this appliance can
be guaranteed only when it is connected
correctly to an efficient earth system, in
compliance with current standards.
