Installation
The machine should be sited on a level concrete floor. Dusty or draughty areas will compromise
machine performance but it is important to allow enough space (750mm) around the machine to
allow access into the various panels and to ensure a good airflow to prevent overheating. During all
of the following installation ensure that the power supply is properly isolated.
Electrical connection
An electric supply of correct voltage, current & frequency is required.
An isolating switch with facility to be locked in ‘OFF’ position and capable of handling full current
should be wall mounted, within easy reach of the operator.
380-415V Three phase supply
Using 3 phases, Neutral and Earth connections STAR configuration. 3P, N & E
The major current consuming devices within this machine are 230V single phase. For 3 phase
machines each phase of a standard three phase supply should be connected to the L1 L2 & L3 of
the machine isolation switch. A neutral wire of full load capacity is required in this case. An Earth
stud is provided.
220-240 V Single phase supply
Using 1 phase, Neutral and earth connection – 1P, N & E
The major current consuming devices are 230V single phase. Machines are fitted with a 3 Pole
Isolator switch. Connect both Live & Neutral field feeder wires to the Switch terminations L1 ( Live),
L2 ( Neutral). An Earth stud is provided.
208-230 V Twin phase supply (North America)
Using 2 phases and earth connection – 2P & E
The major current consuming devices are 230V. Machines are fitted with a 3 Pole Isolator switch.
Connect both Live phases of the field feeder wires to the Switch terminations L1 & L2. An Earth stud
is provided.
Important notice on 3 phase & neutral connections
To prevent damage of components it is highly important to check that the three phase and neutral
connections are correct. The machine colors for wiring are as follows:
Brown L1 - Phase 1 Blue Neutral
Black L2 - Phase 2 Green/Yellow Earth or Ground
Grey L3 - Phase 3
After making connections to the isolator switch in the rear cabinet it is essential to verify that the
phases and neutral connections are terminated correctly. The three phases must be connected
to the connections L1, L2 & L3. The Blue neutral connections must be connected to the terminal
labelled N.
Verify these connections using a volt-meter / multi-meter by measuring the voltage potential
between the Neutral and each phase in turn. The voltage between each phase and the neutral
should measure 220 – 240V ac. Once this is confirmed the Electrical box cover may be fitted and the
isolator switch turned on.
