VFD Wiring
WARNING: Please exercise extreme care when setting up your VFD and Spindle. These are not
toys and can lead to injury or death if not handled correctly. If you have any doubt contact a
suitably qualified electrical technician to assist with your installation. VFD's are complex devices
that MUST be installed by a certified person and treated with respect not only because they
contain High voltages but also because incorrect configuration of a VFD can destroy both the VFD
and the Spindle.
Ensure you power down your VFD before making wiring changes
Plasma Wiring
WARNING: Please exercise extreme care when setting up your plasma. These are not toys and
can lead to injury or death if not handled correctly. If you have any doubt contact a suitably
qualified electrical technician to assist with your installation. Plasma's are complex devices that
MUST be installed by a certified person and treated with respect not only because they contain
High voltages but also because incorrect connection of a plasma can cause damage to your
MASSO.
Earthing is very important to the proper operation of any plasma machine. Correct earthing not only
allows the Arc to work as it should and produce good quality cuts it also reduces noise generated by
the plasma from causing issues with THC and MASSO operation. Please earth your plasma in
accordance with best practices and the manufacturer's instructions.
Control of External mains operated devices
WARNING: The wiring of Mains operated devices MUST be installed by a certified person in
accordance with the electrical regulations of your country.
While the MASSO relay module is rated for 240V 5amp it is recommended that you do not mix low
voltage and mains voltages on the same relay module. A better option is to use the MASSO relay
output to operate a separate relay or relays located elsewhere within your control cabinet. Keep all of
the mains relays together and shielded against accidental contact.
