The machine may only be operated under normal temperature and humidity conditions, especially
only in absence of corrosive or inflammable vapours. At temperatures lower than 10 °C or higher
than 30 °C, there may occur the following problems: The spindle might not start running at low
temperatures. The stepping motors might run hot or step losses may occur at more than 30 °C in
the surrounding air.
In order to ensure a sufficient cooling, the equipment feet may not be removed, otherwise not
enough air will pass through the controller – Overheating and destruction of the end phase may be
the result.
The controller is designed to run at normal ambient temperatures (25°C) and should be operated
in an open set up with dry, dust and aggressive steam free environment.
If the controller is used within a closed cabinet or room temperatures higher than 25°C, you have
to supply additional measures for ventilation.
Increased dust load must be prevented by suitable measures.
Operation in an aggressive, dusty, humid, extremely hot or hazardous environment is at the
user's own risk and responsibility.
The user has to care for appropriate precautions and protective devices, Any liability for damages
arising in such an environment by the operation, are hereby expressly excluded.
Noise
With the HF-spindle running at full speed and the vacuum cleaner on, the noise pressure level at
1 m distance is 86 dB(A). Operators have to wear ear protection.
Dust
It is necessary that the standard vacuum cleaner is always being used during operation on printed
circuit boards. The vacuum cleaner must be OFF during and after use of alcohol or other inflam -
mable or explosive liquids (i. e. used for cooling when milling aluminium). Individual operating con-
ditions may require that an extraction unit with higher rating or the optional protective enclosure be
installed.
Power supply
The machine power supply has a wide range AC input. You can run it on any common single
phase mains supply. If the power cord supplied with the machine is not suitable for your country,
please replace it. In this case it is urgently required that you ensure correct grounding to PE.
Attention!
You must disconnect the machine from the main supply and wait until DC voltages
are low prior to opening the control unit or to pulling cards off from it. We deny any liability if al -
terations to any mechanical, electric or electronic components of the machine are made. Prior to
any manipulation to the control unit, check that the machine has been disconnected from the
main supply.
Please make sure to fix the cable connection with screws. Do not pull the cables while the ma-
chine is under power. First switch off controller and wait for potential equalisation.
On the rear of all machines, there is one socket for a 3.5 mm audio plug, to be used with the va -
cuum cleaner switch box (pict.6). This adaptor will turn the vacuum cleaner on and off together
with the spindle. It comes in a black plastic housing with AC inlet and outlet for European mains
sockets and should be used with the vacuum cleaner that we supply, or i. e. with a liquid cooling
pump for aluminium routing. If you connect other devices, power rating must not exceed 1500
Watt.
