Distance requirements between high-frequency leads and control cables
Electromagnetic interference (EMI) can occur if high-frequency leads (such as the pilot arc and
negative leads) are too close to control cables (such as the 120 VAC power, CAN, and EtherCAT
®
cables).
If possible, use a separate track to isolate each lead and cable.
If separate tracks are not possible, Hypertherm recommends a minimum separation distance
150 mm (6 inches) between the high-frequency leads and control cables. Separate the pilot arc
lead, negative lead, or any power cables that have a voltage higher than 120 VAC from the
following:
 CAN cable
 Power cable (120 VAC)
 CNC lead (EtherCAT, serial RS-422, or discrete lead)
Distance requirements for ventilation and access
 Ventilation
 Do not block the ventilation louvers on the corners or bottom panels of the front and
back of the plasma power supply. A separation distance of least 1 m (3.3 feet) is
required for ventilation.
 Do not block the ventilation louvers on the gas connect console. A separation distance
of least 1.27 cm (0.50 inch) is required for ventilation.
 Do not block the ventilation louvers on the torch connect console. You must use the
mounting brackets to allow space between the console and mounting surface.
 Service and maintenance access – Hypertherm recommends a minimum distance of
1 meter (3.3 feet) between the plasma power supply and other system components, or
between the plasma power supply and an obstacle.
