Warnings
This equipment must be installed by qualified personnel.
Refer to the Operating Handbook for the proper use and maintenance of this
equipment. Failure to observe these instructions may result in safety hazards.
Service work must only be carried out by personnel who are aware of the
potential risks of working on live equipment.
The front panel mains switch must not be relied upon to provide adequate
isolation from the mains supply for servicing or maintenance purposes. If full
isolation is required, remove the mains input cable.
Equipment must be fully earthed to prevent dangerous electrostatic charge
build-up.
The user should be aware of the potentials that may exist on any vacuum
feedthrough connections. Avoid contact with the Thermocouple vacuum
feedthroughs, especially if they are not grounded.
It is the responsibility of the user to consider the safety requirements of
hazardous materials used with this equipment and the consequence of any
leakage, however caused. Consider possible reactions with materials of
construction. Any equipment returned to UHV Design Ltd must have the
correct Declaration of Contamination securely fastened to the outside of the
packaging.
Take great care when changing any of the temperature control loop
parameters; this could have a serious effect on the stability of the control
system.
Do not operate the DC Power Controller unit with any of the covers removed.
Allow adequate ventilation around unit, keep bottom cover rear clear and do
not cover rear panel fan.

The PSU-DC-XXX must be used
•Altitude below 2000 meters.
•Temperature for safe operation: 5 °C to 40 °C.
•Maximum relative humidity: 80% for temperature up to 31 °C
decreasing linearly to 50% at
40 °C.
•Power supply voltage fluctuations not to exceed ±10% of the nominal
voltage.
3.1 Mains Input Power

QuickStart guide and website for full details and downloads.
Eurother iTools
1. iTools WIZARD (free download)
Allows modification of the Eurotherm module configuration settings such as ramp rate and
process time, this can be simpler than using the front panel buttons. These configurations can
be saved and up/downloaded. Note be cautious of changing settings as it can have
unintended consequences. It is recommend that the as supplied configuration is saved as a
back-up, before any changes are made.
