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.

3 INSTALLATION
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
The DC Power Controller operates with mains voltages of 100-230Vac
50/60Hz. Input power requirement is 3.2KVA max. ensure the mains
supply is suitably rated.

The cause of any repetitive fuse blowing must be investigated and
resolved.
3.3 Mains Input
Use the supplied Neutrik connector (32 Amp rating) and connect to local
mains supply via suitable mains cabling. Insert connector and twist,
ensuring lock is at the top of the connector. Minimum 3-core cable size for
230V is 0.75mm2 and for 110V is 1.5mm2. Keep cable lengths as short as
possible.
3.4 Earth Stud
A rear panel Earth Stud is provided for connection to a well bonded earth.
Use copper braid of minimum 4.0mm2.
