Distance requirements between high-frequency cables and
control cables
To prevent noise issues, do not put high-frequency cables and control cables too near each other.
EMI can occur if high-frequency cables (such as the pilot-arc and negative cables) 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 cable.
If separate tracks are not possible, Hypertherm recommends a minimum separation distance 150 mm (6
inches) between the high-frequency cables and control cables. Separate the pilot-arc and negative cables,
or any power cables that have a voltage more than 120 VAC from the following:
■
CAN cables
■
Power cables (120 VAC and 220 VAC)
■
CNC lead (EtherCAT, serial RS-422, or discrete lead)
Distance requirements for ventilation and access
Make sure that all system components have sufficient open space around them for ventilation and service
access.
Requirements for ventilation
■
Do not cause blockages near ventilation louvers on the corners or bottom panels of the front and rear
of the plasma power supply. A separation distance of least 1 m (3.3 feet) is required for ventilation.
■
Do not cause blockages near the fan inlet grates on the front of the cooler or the rear ventilation
louvers on the rear of the cooler. A separation distance of least 1 m (3.3 feet) is required for ventilation.
■
Do not cause blockages near 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 cause blockages near the ventilation louvers on the TorchConnect console. You must use the
mounting brackets to allow space between the console and mounting surface.
