Gas and electrical supply requirement
Gas supply requirements
The Bugbox workstation requires 2 gas supplies;
Anoxic mixed gas (up to 5.5% hydrogen, up to 10% carbon dioxide, remainder nitrogen)
Oxygen free nitrogen.
The maximum permissible concentration of hydrogen in the anoxic mixed gas is 5.5%. The use of
any other gas(ses) will invalidate the warranty and may cause serious injury.
Gas regulator requirements
Gas regulators must be used with all gas supplies to the workstation. A 2 stage regulator must be used
for each bottled gas supply. Regulators should be available from your local gas supplier. Ruskinn
Technology Limited does not supply gas regulators.
The gas regulator should provide a minimum supply pressure of 3 Bar Gauge (42psi). The maximum
supply pressure permissible is 4 bar gauge. A supply pressure greater than this will damage internal
components of the workstation and will invalidate the warranty.
Electrical supply requirements
The workstation must be connected to a mains power supply. A power cord is supplied to connect the
workstation to the mains supply. Only the power cord supplied should be used to connect the
workstation to the mains supply. It is advised that the workstation be located no greater than 1 metre
from the plug socket. The plug socket should not be obstructed by the Bugbox workstation. The
workstation must be connected to a protective earth.
Voltage and frequency requirements
To ensure safe operation of the workstation, it must be connected to a supply of the correct voltage
and frequency as shown in the rating label (item 3 Figure 8). The mains supply voltage fluctuations
must not /- 10% of the nominal mains voltage.
Power consumption
Figure 3 shows the power consumption ratings;

Power consumption
240V AC, 50Hz
150 W
110V AC, 60Hz
200 W
Note: The power consumption is for normal operating conditions with no equipment connected to
the internal power supply. Power consumption will vary dependent upon the conditions inside the
workstation chamber and the conditions inside the room the workstation is located in.
Powering the workstation
To switch the workstation on, press the power switch (item 2 in Figure 13). To switch the workstation
off, press the power switch (item 2 in Figure 13). Note: A glove port should be left open when the
workstation is switched off, as the pressure inside the workstation will decrease as the workstation
cools. The open glove port will allow the pressure inside the workstation chamber to equalise with the
external pressure.
