10.3 ELECTRICAL INSTALLATION.
The electrical installation of the mixer must conform to the local electricity board
regulations. When installed in the United Kingdom the installation must be in accordance
with the current edition of the IEE Regulations for electrical equipment in buildings and
the Electricity at work act.
A competent person must carry out the electrical installation.
The technical data shown in Table 1, page 30 details the electrical requirements for the
various mixer options.
The HL600 mixers are "class I" appliances where the protection against electric shock
does not rely solely on basic insulation. An external electrical isolator and MCB/fuses
(both items supplied by others) must be fitted to the incoming electrical supply to the
mixer. In addition a 30mA residual current device is strongly recommended to provide
extra protection.
Check that the impedance of the earth circuit is safe and operating at the
correct value.
The machine must be equipotentially bonded. The earthing screw is situated at
the rear of the machine and is identified by the symbol shown on the right.
Check the earth bonding resistance is less than 0.1Ω and the insulation resistance is
greater than 2 MΩ.
10.4 ELECTRICAL CONNECTION.
Refer to the wiring diagram supplied with the mixer and enclosed in the document
envelope. Note: Incoming power wires must be looped thru ferrite core before
connecting to terminal block TB1.
10.5 OPERATOR TRAINING.
Take time to explain the correct operation and cleaning of the Legacy mixer to the users
referring to this manual. Leave this manual with the operator and explain that it is
important to use it for further reference.
