6.4. Electrical Connection
The electrical connection of the delivered machine must be done by an authorized electrician and in
accordance to valid local regulations.
The wiring made at the factory, and the electrical connections to be done during
installation, are shown in the electrical diagram attached to this manual.
The
machine’s specific electrical data is given in this manual, section 3.2, page 16 above,
as well as on its serial number plate located on its outer cover (in cabinet assemblies
there is also an additional plate inside the cabinet).
Also note that the electrical connection of level sensors at the tank, as well as their connection to the
GTS-processor in the kitchen, as shown in the enclosed electrical diagram, applies to the level sensors
of Disperator´s manufacture according to section 7
below. For other makes and solutions of level
sensors, please contact Disperator or your dealer.
6.4.1. Supply Voltage
Check that the supply voltage to be connected corresponds to the specified 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 specified in
section 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 option from Disperator.
6.4.4. Cable Dimension
Use connection 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
specified 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 flexible sleeve or conduit. The cables must never be kept
on the floor/floor plate.
6.4.6. Earth Wire
a) The earth wire must be longer than the main voltage wires, when connecting to the cable
terminal block. This gives earth protection in case the voltage wires become unfixed 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 until the motor comes
up to speed, why the RCD without intended reason will trip. Note also that
when the machine’s electrical connection 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.
