6.4. Electrical Connection
The electrical connecon of the delivered machine must be done by an authorized
electrician and in accordance to valid local regulaons.
The wiring made at the factory, and the electrical connecons to be done during
installaon, are shown in the electrical wiring diagram aached to this manual.
The machine’s specic electrical data are given in this manual, secon 3.2
above, as well as on its serial number plate located on its outer cover (in cabinet
assemblies there is also an addional plate inside the cabinet).
6.4.1. Supply Voltage
Check that the supply voltage to be connected corresponds to the specied voltage on the
machine’s serial number plate.
6.4.2. Mains Fuses
Check that the supply voltage for the delivered machine is fused and protected as specied in
secon 3.2 of this manual.
6.4.3. Wall/Bulkhead Mounted Electrical Security Breaker
A separate wall / bulkhead mounted main electrical security breaker (circuit breaker) must be
connected in the incoming power line to the machine. The electrical security breaker is not
included in standard delivery but is available as an opon from Disperator.
6.4.4. Cable Dimension
Use connecon cable having 1.5 mm² wires for machines having a rated current up to 14A. For
machines having a rated current above 14A, use 2.5 mm² wires. The rated voltage and current is
specied on the machine’s serial number plate.
6.4.5. Cable Protection
All electrical cables must be protected against damage by being securely
fastened, for example to kitchen furniture or wall/bulkhead. If there is a risk
that the cables can be damaged, for example by passing trolleys, then the cables
must be protected by a exible sleeve or conduit. The cables must never be kept
on the oor/oor plate.
6.4.6. Earth Wire
a) The earth wire must be longer than the main voltage wires, when connecng to the cable
terminal block. This gives earth protecon in case the voltage wires become unxed in the
cable nipple, allowing them to be pulled from their terminals.
b) The machine must not be connected via residual current device, RCD (also
called earth leakage circuit breaker). The reason is that the currents in all
3-phase motors during start-up are out of balance unl the motor comes
up to speed, why the RCD without intended reason will trip. Note also that
when the machine’s electrical connecon is permanently installed through
a wall / bulkhead mounted electrical security breaker (see item 6.4.3.
above), usually under current rules in most countries no RCD is required.
6.4.7. Direction of Rotation for the Disposer
The disposer operates correctly irrespecve of the motor’s rotaonal direcon. It is therefore
irrelevant in which sequence the electrical phases are connected to the disposer motor.
