Bend radius requirements for hoses, cables, and leads
The following hoses, cables, and leads cannot bend beyond a
minimum bend radius of 15.25 cm (6 inches):

Pilot arc lead

Coolant hose set

Power cable

CAN cable

3-gas hose bundle for the Core gas connect console

5-gas hose bundle for the VWI or OptiMix gas connect
console

Gas supply hoses
Distance requirements between high-frequency leads and control cables
Interference and electrical noise 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.
