3.6 Electrical System (1-phase mains)
If you do not operate a 1-phase mains machine, please disregard this section.
Machines powered by 1-phase mains electricity are generally the same as other models, but
are fitted with an electronic Variable Speed Drive (VSD), which operates a 3-phase 2-pole
electric motor driving the hydraulic pump. The control voltage is 24VDC.
The motor only runs when the RAISE button is pressed; the cradle is lowered by gravity alone.
3.6.1 International conformance
The exact specifications of 1-phase machines differ depending on the standard voltage and
frequency of 1-phase mains power in the intended country of use. Both the transformer
(
§3.6.2 ) and VSD ( §3.6.3 ) are specified to suit local norms.
A list of 1-phase power standards used in different countries and territories may be viewed at
this web address:

Connecting the machine to a power supply for which it was not designed may damage
the motor and electronic components. Consult an electrician if you are unsure.
3.6.2 Transformer
1-phase machines are fitted with a transformer which outputs 24VDC current to the control
systems. The input voltage and frequency are specified to suit standard 1-phase mains
power in the intended country of use.
3.6.3 Variable Speed Drive
1-phase machines are fitted with an electronic Variable Speed Drive (VSD), which outputs 3-
h se/ VAC/ Hz c e he ‘s c f g ’. he V D v ge d
frequency are specified to suit standard 1-phase mains power in the intended country of use.
The VSD has many parameters that can be set to suit specific applications. They can be
modified or calibrated by a PC that has the appropriate program and cable drivers loaded.
A joystick controller can be provided with the VSD, allowing progressive control over the
lifting speed.
Residual voltages may be retained in the VSD inverter after it has been disconnected
from the power supply. Use extreme caution when servicing electrical components.
